Data Recovery - Hard Drive Crash? How to Recover Your Lost Data, Quickly!

noreply@blogger.com (Admin) — Sat, 02 Aug 2008 20:42:39 PDT

Due to the advancements in technology, computers have become an essential tool used both for business and personal purposes. It is quite difficult to keep up with the times without a computer with an Internet connection which will keep you updated. With the onslaught of the Internet, it has become an even more essential tool.

If you have a computer set and you have been using it for some time to store data, one of the most dreaded problems that you might - and you will encounter – is a hard drive crash.

At one time or another, you would have accidentally deleted a file and if you are not very computer-savvy, you might think that there is no way for you to recover your data.

When this happens, all you have to do is look into your ‘Recycle Bin’ or Trash folder if the file is still there and restore the file by dragging it onto the desktop. You can also use a file-recovery system which can scan your disk for recoverable data.

However, it is a different case once your hard disk crashes. You may lose all of the important data stored on your hard drive and without a dependable back-up system, you might not think it possible to restore the lost files.

Do not lose hope because there is still a number of solutions available out there to recover your lost data in case your hard drive crashes. First, take a look at the symptoms of a hard drive crash, which would mean that all the important data stored on your computer may be lost:

1. You hear a ’clicking’ sound on your hard drive. This basically means that you may have a corrupted ROM or read-only memory chip, or it could also be caused by an electrical problem.

2. You see a blue screen while booting up your computer. This may mean that your computer’s OS or operating system is corrupted or damaged.

3. Your computer often re-boots, restarts, hangs, or freezes. This may be caused by a virus on your PC, that is why it continually restarts or re-boots even in the middle of an operation. A bad sector causes your computer to freeze or hang while processing data.

4. You keep on receiving error messages while in the middle of an operation. You may receive a “Drive not formatted” error which means that the partition of your hard drive is damaged.

Another error message that you may receive is “Operating system not found”. This error appears when your OS is or the files on your hard drive are damaged.

Should you encounter any of these hard drive crash symptoms, here are some “first-aid solutions”:

- Turn your PC off if you hear a clicking sound on your hard drive, and if you are technologically challenged, get professional help – quick! – before losing your precious data.

- Take note of what happened, how your PC behaved, and remember any error messages to make it easier for a technician to troubleshoot.

- Use a data recovery software in the event of a hard drive crash. Such software which recovers data includes tools to restore deleted files from your Recycle Bin folder. It can also restore damaged and lost files caused by a virus, or power outage, or bad disk sectors.

-Windows and MAC users should also be aware of the basic file recovery capabilities offered by the system of these computers.

Finally, it is always a good practice to take preventive measures even before your hard drive crashes. Make it a habit to back up and even double back-up your most important files.

Flash Data Recovery

noreply@blogger.com (Admin) — Mon, 28 Jul 2008 08:27:43 PDT

Flash data recovery in most ways is like recovery from any other media using FAT. ... In case of lost data, flash data recovery is just like ...

Flash disks have become ubiquitous media for everything from computer data, mp3 players and digital cameras. It has replaced the floppy disk as means to carry data around. Flash disks are solid-state devices and, therefore, have no moving parts. Plugging it into the USB drive, the flash drive is automatically recognized by the computer without any need of installing additional software. With expected lifetime measured in hundreds of thousands of write-erase cycles, flash drives are expected to last up to 10 years. That's more than twice that of a hard disk.

Flash disk portability however leads to a higher probability of damage due to environmental factors. Aside from the regular causes of drive failure, flash drives could get wet in the rain, the casing could shatter when it is accidentally dropped, or it could be damaged while inside the camera.

The difference in data storage between a flash drive and a regular hard drive or a floppy is due to the data residing on a chip. This allows for a truly random access across the whole media. In fact, the disk access algorithm makes sure that the data is spread evenly among data sectors with the use of "wear leveling algorithm." The flash disk has a finite number of write or erase cycles. If it were to keep on writing to a particular sector, that sector would literally wear out from use much earlier than the other sectors. The wear leveling algorithm ensures that the sectors wear out evenly. And also because of the wear leveling algorithm, when a data sector wears out, the rest of the disk is sure to quickly follow.

In some instances, the camera cannot distinguish between the file system on the flash disk and force a format. Early flash disks used FAT12 or FAT16. FAT32 is used by current generation large capacity flash disks. If the digital camera fails to detect the flash drive's capacity it might wrap around data while writing the photo and over-write system areas.

There are times the flash disk could not be read by the computer. Though attributed to the computer, this is an error caused by the camera or MP3 player OS. Unplugging the drive while it's writing data may also cause a corrupted flash drive.

Flash data recovery in most ways is like recovery from any other media using FAT. The only difference is the location of the media files. The data can be recovered by using data recovery tools capable of reading FAT. Typically for cameras, the file structure is fixed. The camera's limited operating system will write to a specific folder on the directory. The same goes with MP3 players. The mp3 files have to be located in a specific directory for the mp3 player to locate and play them. Some specialized tools look for the specific folder where the media files should be.

Treating all the data on the disks as data files, disk recovery programs or other utilities are capable of correcting any errors. The Windows CHKDSK utility treats the disk like any other drive.

In case of lost data, flash data recovery is just like recovering data from any other medium but, again, with slight differences. Because the data is stored differently, there are more tools available for flash data recovery. Available tools and utilities include flash data recovery specializing in picture files or mp3 music files. Other specialized utilities which can be used for flash data recovery are those which specifically recover data from FAT drives. In case the pictures were accidentally erased from the camera, these utilities are also able to recover them and recover the picture.

In some cases, data recovery can be even simpler. A flash disk recovered from a lake or which got wet from the rain may still be usable after making sure that the circuitry is completely dry. And a flash disk with a broken case might even be usable. In both instances, it would be good to test first by plugging it in. If the drive is still readable, just copy the files before deciding what to do with the flash drive.

Free Data Recovery

noreply@blogger.com (Admin) — Mon, 28 Jul 2008 08:25:48 PDT

Free data recovery refers to freeware or free software applications ... Most specialist would say that the best free data recovery system is ...

Data recovery is the process of reviving data that have been lost due to physical damages like hard drive head crash, scratched, water-damaged or broken disks and tapes, and defective mechanism. Free data recovery refers to freeware or free software applications or utilities that anybody can download from the Internet for personal use.

Aside from physical causes, data could get lost when the file system is formatted; when the operating system running the machine is reinstalled; when files get deleted accidentally; when there is a virus attack; and when the system gets corrupted. These damages can happen to anyone and any computer anytime.

Most specialist would say that the best free data recovery system is to be pro-active in file management. There should always be a backup system especially for very important data. The backup will definitely make things easier and less frustrating when the unfortunate happens.

It's a good thing that there are ways to recover your lost or damaged files. If the data loss has a large impact on your business or it's a matter of national security or something, the wisest move is to go straight to the data recovery companies who have experts that can work on your problem.

But, if you think you know what you're doing and you have a technical background in computers and storage devices, then there are two options for you: purchase a data recovery software package or download a free data recovery utility online.

Obviously, there is a huge difference on the cost for each of these two. Software packages could be expensive but they could really offer a lot to the user. The freeware mostly downloadable on the Internet entails no cost although some authors ask for donations for their efforts to keep on going.

Now, let's say you accidentally formatted your drive and you have no backup. The freeware can help you recover them but you have to bear in mind a few things:

Stand up and leave that computer which uses the drive that needs the recovery system. You can't afford disk-swap activities that could damage the data even more.

Never install or download the free data recovery software from the same machine you want to recover data from. Go to another computer and save the program on a flash drive and run it directly from there.

Never save the recovered files on the same hard drive you recovered them from.

If the machine is making strange noises or is returning error messages, stop the installation. This could be a sign of hardware malfunction.

Follow the tips if you're planning to download free recovery software to address your data loss predicament. Remember to be cautious when getting freeware to avoid getting any more problems.

Be warned also about these websites that claim to give free data recovery programs, some could be deceiving. They would say the program is free but you'll soon find out that these are just demo versions and soon you will have to purchase the real thing to get the benefits or more features. The freeware that is genuinely free are those utilities you can download and really pay nothing for.

The Basics of Laptop Data Recovery

noreply@blogger.com (Admin) — Mon, 28 Jul 2008 08:23:56 PDT

For a laptop data recovery, a full restore from existing backup can ... For laptop data recovery the hard disk is isolated and an image of ...

With the rise of a mobile lifestyle and telecommuting, laptops have proliferated and become almost as common as the home computer. In some instances the laptop has become the home computer. The reason for the popularity is the portability it affords the computer user. And with the ability to take the laptop anywhere, this leads to unexpected damage from the elements and to heavy wear and tear.

Because the laptop was designed for mobility, this makes it more prone to damage. Aside from the regular wear and tear from lugging around the computer, there are greater risks for accidents. Accidentally pouring coffee over the laptop, or dropping it, running the car over the case, or even sitting on the laptop can damage the unit. Physical damage to the laptop case can make it unbootable.

In most instances, the laptop is a secondary computer or is wired to an office LAN, it is prudent to regularly save data to a desktop or a server. In case of loss, a copy of important data is stored at the office or at home. Backup utilities take advantage of this connectivity and can schedule an automatic backup of files to the desktop computer or the office file server.

Frequently, laptops come with a recovery disk CD. The laptop recovery disk CD contains the compressed hard disk contents prior to the laptop use. In case the hard disk fails, or the user wants a full re-write, or re-install of the laptop, the laptop is booted up from the laptop recovery CD and a full reinstall is done. For a laptop data recovery, a full restore from existing backup can be done after the system has been re-installed.

The laptop recovery disk CD is not to be confused with the Windows recovery disk. This is also different from recovery disks from data recovery programs. The Windows recovery disk is used when trying to boot a computer with a corrupted hard disk, or a computer which fails to boot. It repairs the Windows system files. Recovery disks from backup and recovery software vendors allow the user to boot up the disk and do a laptop data recovery by restoring the hard disk data from a backup.

Some laptops have intelligent hard disks that help avert data loss. The Self-Monitoring Analysis and Reporting Technology (SMART) for hard disks informs the user of probability of a hard disk failure. A laptop with SMART hard disks would inform the user if a hard disk crash is inevitable. This gives the user enough time to back up important hard disk data. It also allows the user the luxury of going to a service center to diagnose the computer before the hard disk fails.

In case of accidental damage, there are laptop data recovery services, which the owner can avail of. These laptop data recovery services are full service repair bureaus which check the computer parts and not just the hard disk. The owner sends the unit to the service center for laptop data recovery, laptop checkup and diagnostics and repair. For laptop data recovery the hard disk is isolated and an image of the hard disk data is created prior to repairing it.

With these service bureaus the laptop data recovery can be done even if the hard disk is completely damaged or is not working. Laptop data recovery can be done for inaccessible drives or partitions, corrupted files or disks, virus attacks, overwrites, accidental file deletion, laptop hardware component failure, hard disk crashes, fire, flood and water damage, media contamination or damage, and accidental formatting or partitioning.

Laptop data recovery may be a longer process than data recovery for a desktop computer. There are more reasons for a hard disk failure or laptop damage to happen. However, for different scenarios of hard disk failure, boot up failure or data loss, there are different laptop data recovery solutions available to the laptop user.

Which Data Recovery Software? Restoring Deleted Data

noreply@blogger.com (Admin) — Mon, 28 Jul 2008 08:22:14 PDT

Which data recovery software will fit your needs? And do they really work, and work well? Well, first let's examine that last question here. ...

Which data recovery software will fit your needs? And do they really work, and work well? Well, first let's examine that last question here. We all know how various government agencies like the CIA, FBI and IRS can easily take whatever data they are searching for from any computer, regardless of whether or not the system was "purged of all data".

Why is this so? It is because files and data are never really completely removed from our computer systems! Anything "lost" is never truly lost, and is just sitting there somewhere in your computer, waiting to be retrieved. You just need to know which data recovery software to use to get to it all.

Which data recovery software is the best? If you've accidentally deleted a file, and only found out about it after the recycle bin was emptied, then most retrieval software programs can handle this. If your computer crashed and you had to reboot the system and lose any and all unsaved data, then most data retrieval software programs can take care of this too.

But what if your computer had caught a terrible virus, and you had to "wipe the slate clean" and begin a fresh start anew, reformat your entire hard drive, and reinstall Windows or any other operating system your computer uses? Surely everything is lost and gone forever for certain by now, right? Not so in the least! The information that you thought was lost is STILL on somewhere your computer system!

There are a few data retrieval software packages out there that can handle this as well, and with a minimum of fuss. When you search for which data recovery software to use, find one that can handle such a task and you're pretty much set for any situation. All your data retrieval needs will be met just a mere few mouse clicks away!

Backup Your Computer Data Or Lose it Forever

noreply@blogger.com (Admin) — Mon, 28 Jul 2008 03:54:51 PDT

When was the last time you backed up your computer data? How many files and folders do you have on your computer? A rough guess will do. Personally I have over 85GB of data, music, Photoshop files and emails that I desperately would not want to lose.

Backing up your data files on Windows is a simple and straight forward process that you should complete on a regular basis. I should know as a while back I didn't follow my own advice and lost all my files when one of my hard disks became corrupted.

I had to re-install Windows XP and re-download all the programs I could remember having. I also had to buy a couple of software programs again as the drive that failed had all my emails on it, so I couldn't prove I had purchased the software.

Windows has a built in back up facility that is adequate. It's not exactly the best program out there, however it will allow you to back up your data for free. To access it Click Start, highlight All Programs, highlight Accessories, highlight System Tools, and then click Backup to start the wizard.

Within the wizard you will be asked exactly what files you wish to back up and to where. What files you back up will help you make a decision on where you wish to back up.

If you wish to back up only really critical files that are not that huge you may be able to back up onto a flash drive or memory stick. These are getting cheaper and cheaper and 8GB or 16GB versions are very cost effective these days.

If you wish to back up more files, or even all of your files then you may be best using a portable hard drive. Portable hard drives offer offline storage and as long as you store it away from your computer [no point storing it in the same room or building really], offer a good worthwhile solution.

Portable hard drives are very similar to flash drives in that the price is very reasonable and if you are serious about keeping the data on your computer redundant, then it is cost effective, especially if you do have a computer or hard drive failure.

There are quite a few alternative free backup software options available, that for a home user will be more than sufficient. There are paid for back up programs also that are available, they maybe would be better suited to businesses that require more powerful and scalable

Another option is for online storage. There are many free online storage options available as well as paid. If you can afford it, paid for online storage is best as you should be given guarantees by the online storage merchant.

However you back up your data and what medium you keep it backed up on, having a regular back up schedule and keeping to it will give you piece of mind and will safe you hassle further down the line when one of your computer components fail.

Data Recovery - Secrets Behind The Technology of Data Recovery

noreply@blogger.com (Admin) — Mon, 28 Jul 2008 04:21:37 PDT

..If you're looking learn more about the process of data recovery, then you will ... Another way to achieve data recovery, is through the disk ...

If you're looking learn more about the process of data recovery, then you will want to read this article. Specifically I will give you different definitions of data recovery, as they relate to specific situations. Also I will offer some tips on data recovery software, and how to apply them to get the objective achieved that you desire.

To put it simply, data recovery is recovering information that is either been corrupted, damage, failed or in other ways not accessible. Sometimes, you might need to recover data from your hard drive, that your computer is telling you is currently corrupt. Other times, it might be data from CDs and DVDs, or other storage media formats, that you are unable to access.

Damage to your information can occur through physical failure, such as your CD-ROM getting scratched, or your hard disk drive simply malfunctioning due to a mechanical failure. In general, all physical damage across some data loss. For physical damage, data recovery generally won't be able to be something you can fix your self. It requires that you fix your hard drive in an environment that is sterile, so no more dust can damage your disk further. Also, it usually requires certain technical expertise and specialized hardware to make these repair.

Sometimes, the only hope is to boot up the bad drive long enough to quickly grab the information, and save it to a backup.

Another way to achieve data recovery, is through the disk imaging file on your computer. This is usually the trick for when there's been corrupted file information, rendering your files inaccessible. You can extract the raw data captured on your disk image, to recover the data that is missing or incomplete. There are a lot of free tools out there that can recover all the damage, in most cases.

Whenever you use data recovery software, there can never be a guarantee that no data loss will occur. Sometimes certain files share the same data, and not losing data for one of the files is essentially impossible to get around. However, the result is it that recovery software often restores a lot of data that users have otherwise written off as hopeless.

In conclusion, I have given you a definition of data recovery, and also have examined some points that consider for those in need of recovery. I have given you some options to look into for data recovery software, depending upon your needs.

Data Recovery - The Solution For Data Loss

noreply@blogger.com (Admin) — Mon, 28 Jul 2008 04:24:41 PDT

data recovery is the word of law for people who use computer in ... There are mainly two categories of data recovery: Common Recoveries and ...

Is there something more annoying than losing a paper you saved in your computer, on which you worked for weeks? I guess not. For this reason, data recovery is the word of law for people who use computer in their jobs or for school or college.

Many things can cause data loss, such as accidentally deleting files, having your system invaded and corrupted by hackers, power failure when you hadn’t saved what you had been writing and other hundreds of possibilities. The truth is: everybody that uses a computer will experience data loss at some point in their lives.

Well, if we are not safe from experiencing data loss, what can help us recover the data we’ve lost. If we lose something personal, in our homes, it's not as serious as if we lose some important paper from work.

There are mainly two categories of data recovery: Common Recoveries and Complex Recoveries. The first one consists of recovering the data of a single user, either from a floppy disk or hard disk. Complex Recoveries consists of recovering data from a computer with multiple users.

Using data recovery

Many people think that just because they can't find the file in the folder it was saved to means that they have lost the data and they need data recovery. It's not always like this. We may have accidentally changed the location where the file is saved or even renamed it. Before using data recovery, we have to be sure the data is lost. In general, people can use data recovery either if:

- they deleted the file by accident

- they deleted the file, but regretted it later

- the power failed and they haven't saved the information

- they had their data corrupted, usually caused by intruders

- they found some drives or partitions simplly are not accessible.

Recovering data

Experiencing data loss for any reason is really a nuisance. However, recovering the data may not be that difficult.

We in general forget - or simply are not aware - that all the files we lose, especially if we accidentally deleted them, remain in our computer, hidden somewhere where we can no longer see them. In order to recover the data, we just have to find where it is hidden and save it all again.

The best way to recover data without suffering for days and nights in order to accomplish this task has to do with creating backups of important data. You can save your data on CDs or floppy disks in order to always have a second copy of the file in case you lose it. It's important to keep it as up to date as the original saved in the computer because if you don't do that, the files will be different and you lose information in the same way.

Creating backups of data

One of the biggest problems people have is choosing the data to backup. It is a difficult task, we have to admit it. So, here is a simple list of things considered important enough for people create backups of:

- Financial information, including bank records

- E-mail address book

- Important correspondence

- Business information, especially if we are talking about companies and offices that deal with clients

- Papers from school or college

- Personal projects

- Important documents

People can create backups on the computer, however if they experience a theft, fire or flood it will be lost. That's why it's advisable to backup and save files in different places. In order to get the most of your backups, try to follow some guidelines:

- Always backup! If you are a home user, creating backups once a month is a good idea, however, if we are talking about companies and offices, the best option would be to create backups once a week.

- Avoid volatile data, which is data that is not saved in your computer because you are creating it and haven't saved it yet.

- We are humans and we forget things, for this reason configure your computer to create automatic backups.

Safe data recovery

Data recovery is not that simple do to, but it's not impossible either. In order to do data recovery in the right way, the best thing is to observe some rules:

- Don't try to continue doing data recovery if your computer starts making weird noises

- Running the scan disk is not the best option since it puts more pressure onto the system

- Running utilities that you don't know how to deal with can cause even more damage

- Formatting or reinstalling systems is not the solution either.

A last word: the best thing to do is to create backups and keep them up to date in order to avoid the problem of data recovery..

Hard Disc Data Recovery Software

noreply@blogger.com (Admin) — Mon, 28 Jul 2008 04:26:21 PDT

... Hard disc data recovery is essential considering the way in ... This article basically treats the recovery of hard disc data resulting from ...

A hard disc drive (HDD) unit is a device used in storing digital data/ information most especially in a computer system (desktop, laptop, palmtop).

However, with breakthroughs in technology in the 21st century, other uses of hard disc drive for the storage of digital data/ information needs now include Mobile Phones, digital Video recorders, digital Cameras and Camcorders, Video game consoles, Personal digital assistants (PDA's), digital Audio players, Microvaults, iPods, to mention a few.

Hard disc data recovery is essential considering the way in which blunders and mistakes occur as we utilise our systems and units under various conditions and environment.

You may be held to ransom in the event a problem occurs involving your hard disc drive or main memory.

Such problems which may be caused by different factors include:

1. Mistake on PC owner/ user's part- accidental deletions of files and folders, formatting of hard disc drive

2. Machine error- bad sector, lost chains, cross linked files, power surge/fluctuation

3. Virus infection and spyware attack- deletion of files and data and corruption of the master boot record/ operational system program

...and a host of others.

To have your hard disc crash or become infected with a virus is never a welcome event. At best, it destabilises you because of the great possibility of completely losing your important and precious information stored on it.

When your hard disc fails or develops a problem no matter the degree, you are helpless and at the mercy of any would-be solution (few available tools and the much you know to do) to get your files and data restored or recovered seeing it becomes trapped on the hard drive.

The thought of losing your priced information stored on the hard disc weighs heavily on your mind and even moreso, the time and effort required to reproduce another backup copy...(provided you can access the information/ data at all again).

Work becomes stalled and eventually grinds to a halt until a solution or remedy is sought to salvage at least some of the information stored on the hard disc or system memory.

At best, and in practise, we hardly make backup copies of our files, data and folders containing our information, which even makes hard disc problem or failure quite frustrating whenever such occurs.

Several good and efficient hard disc data recovery software products are now available, and for different applications too.

These hard disc data recovery softwares are specially designed to meet different user needs in the recovery of lost files and data irrespective of the original cause leading to the loss of data and information on your hard disc.

Such interesting and appealing features of these Third Party Software products include:

1. Total recovery of formatted hard disc data

2. Access to unrecognised/not acknowledged/unseen "lost" partitions (FAT, NTFS)

3. Repair of data volumes damaged by virus attacks

4. Recovery of deleted files no longer seen or available in the recycle bin

5. Ability to Undelete missing and deleted files and data

6. Ability to unformat a partition to recover data due to accidental format

7. Ability to relate and function with an unbootable system/unit

Data Recovery Tools For Hard Disk Failure

noreply@blogger.com (Admin) — Mon, 28 Jul 2008 04:29:31 PDT

Data recovery tools make sure that the backup is restored and the user can go back to using the computer in as little a downtime as possible.

From a user viewpoint, the computer is only as good as the data it contains. If the computer can't boot up, it's practically useless. If it can boot up but the files are corrupted and cannot be opened for reading or writing, the file is useless. This happens often enough that data backup and recovery tools are a must with computer users. In fact, it's a good idea to have two copies of important data, just in case the first backup fails. Data recovery tools make sure that the backup is restored and the user can go back to using the computer in as little a downtime as possible.

You might say that the root cause of data corruption is the hard disk. And of all the various parts of a computer, the hard disk is most prone to failure. There are only so many moving parts to a computer. These are usually either fans or the disk drives. And a hard disk spins much faster than a cooling fan. A slowest hard disk spins at 5,400 RPM, and some expensive high performance hard disks spin almost three times faster at 15,000 RPM.

Aside from the processor, the hard disk generates a large amount of heat. The faster it spins, the hotter the disk. Although the expected life span of a hard disk is five years, with the continuous spinning and the generated heat, disks start to fail after three years of use. Within the first three years of use, hard disk failure in one form or another is expected to occur.

Data corruption can occur due to any of a number of reasons. An electrical outage or a spike can cause data corruption. An improper shut down can also cause data corruption. In most instances the data corruption might not go unnoticed. Unless the file is hit and the computer does not work properly, only then will the problem show itself.

Worst case would be when the hard disk's master boot record (MBR) is corrupted or a boot sector develops a bad sector. In which case the computer would not be able to boot up and the user is forced to do a data recovery as well as a hard disk recovery.

Any hard disk recovery effort would also be useless if it does not recover the latest data. Part of any data recovery tool kit would be a backup program and procedure. For data backup, the simplest tool is a file copy on a separate disk. This is especially useful for important files. Recovering from corrupted files on the computer is as easy as copying from the remote computer or hard disk.

It would be better however to have a data backup or a data recovery software. A data recovery software can schedule file backups to a tape backup device or a another drive. Windows has a backup software included called Backup.

Data recovery for corrupted files or folders should not be a problem if the data backup is up-to-date. Windows Backup also has the facility to restore data from backed up files.

When the computer fails to boot up, it might be because the master boot record or the operating system is corrupted, or the partition might be lost. For lost partitions or lost boot records, a simple file backup will not suffice. The computer has to boot up first before it can start any file backup.

Some data recovery tools have the facility to recover hard disk partition information. As with regular file backup, the recovery tool needs a backup. To recover a hard disk, either a hard disk as a whole is backed up (called a mirror) or just the partition. Commercial data recovery packages such as DriveClone and Ghost can backup a partition or a hard drive and recreate it to repair the failed hard drive, or to write it to another hard disk or computer altogether. These programs can boot from a recovery CD and proceed to do a hard disk and data recovery.

For larger installations, there are data recovery software from vendors like Acronis and Veritas which can backup multi-volume disks and RAIDs using disk backups and tape drives.

Hard disk failure and data corruption is a serious concern. In cases like these when the computer fails to boot up, or the data could not be read, it helps a lot if data recovery tools are ready, in use and allows easy recovery of data.
