How to recover data from crashed hard drive

dblacharski

Yes, it's true that everyone should know better, and should be backing up data to an off-site facility on a regular basis. But, in reality, it doesn't always happen, and a crashed hard drive can still be disastrous. When that does happen (and eventually, it will), after steps 1 and 2 (cursing and pulling out one's hair), what comes next? What is involved in data recovery, and how do I know whether my data is lost forever? Or, can I try to recover it?

If you did not put anything new after you lose your files, you chances of data recovery is still there. Why?

When a file is deleted, it seems you just lose the file forever. Actually, the file content still exists on the hard disk, Mac system simply marks the hard drive space as being available for use so that you can write new files. If you manage to start an undelete process before Windows uses that part of the hard drive to write a new file, all you have to do is set that flag back to “on” and you get the file.

Obviously, the sooner you try to recover a deleted file, the more successful you’ll be. But stop a moment and think about the other things that could cause this part of the hard drive to be overwritten. If your hard drive is pretty full, the odds are much greater that Windows will grab your precious unallocated space for its next write. Or, if you defrag the hard drive, you run the risk of unused parts of the drive being overwritten! (This also means that if you are running silent background defrags services like Diskeeper, or if you have defragged utilities scheduled to defrag automatically, you might get blindsided-lose your chance at data recovery-if you don’t halt them until you have your deleted file recovered.

The lesson every computer user learns the hard way is to back up their data. It is not a matter of whether a hard drive will fail, but when.  20 years ago, there were several tools that were quite helpful in recovering lost data from Windows and Macintosh-formatted hard drives, but as the drives have gotten larger and our operating systems have become more complex, the number of available data recovery tools and the quality of those tools has decreased considerably.

 

The first step to take if your hard drive fails is to shut down your machine and try not to panic. Keeping your emotions in check is important to not making mistakes throughout the recovery process.

Commercial programs like Iolo Search and Recover, PC Inspector, and HigherGround Hard Drive Mechanic can help you to recover your hard drive, provided you can mount the failed drive in another computer. This usually requires removing the failed hard drive from your computer and attaching it to a USB-based external drive kit (available for desktop and notebook drives with either ATA or SATA connectors). You’ll want to insure that the external drive kit is USB 2.0 compatible, or it can take a large amount of time to recover your data, because USB 1.0 is much slower. You do not need to be an expert to run these tools, but it doesn’t hurt to employ an IT professional for jobs such as these because they’re often able to breeze through the data recovery process without spending a great deal of emotional energy.

Hi dblacharski,

Popular Mechanics has a helpful article about how to recover data from a dead hard disk:

Don't Panic! How to Recover Data From a Dead Hard Drive
http://www.popularmechanics.com/technology/how-to/tips/4294038

Snippet:

"Let's dispense with the I-told-you-sos. If you find yourself facing a data recovery job, then you have probably forgotten the cardinal rule of computing: All hard drives eventually fail. And you didn't back up your data, did you? We've been there—hey, everybody has to learn this lesson once. Now what?

Panic!

Just kidding. Actually, the first thing to do is determine if it really is a hard-drive failure you're confronting, and not one of the countless other equipment glitches that can cause a boot failure.

Even if the hard drive was crashed, it is possible to recover data from it. As long as the data is nor overwritten. Generally speaking,  crash in a hard dirve or a storage device result from partition error, you may can fix them by formatting, but you will lost all the data. Thus, you have to recover the data first. I has a similar experience before, my gf' s laptop had a hard drive error and counld not boot normally, and I have to  formate the hard drive to reinstall the system, but it was at the price of data loss. After system reinstalling, I googled a software to recover data from the laptop's hard drive, you can get the  version without paying to see whether you data are still there, know more here: http://memory-card-data-reovery.blogspot.com/2013/03/hard-drive-data-rec...

Firstly, if you want to recover data from crashed hard drive, you have to stop using hard drive after crashing.

 

Secondly, crashed data in the hard drive may still be in the memory sectors,crash happens when some sectors suffer from error or other wrongs, and some rescue solutions can fix the bad sectors.

 

Thirdly, when crash happensto hard drive and data is lost from hard drive, you can try to use recovery tool to recover data from crashed hard drive.

If you have a backup disk, then ok, otherwise you need a data recovery software/tool or take assistance from an expert, give advice you which data was lost and retrieve the lost data.
