Software for recovering files after format



First and foremost, do not power on the system with the (accidentally) formatted drive installed. Each time you boot, files may be read and re-written to the drive, over-writing what at this point could be recoverable data.

Next step is to determine what happened. If you accidentally did a "Quick Format" on a disk much of your data is probably safe, as a "quick" format merely overwrites/erases the disk's File Allocation Table or "index" of where the files are actually written, but stops short of actually writing over the files themselves. If a "full" format was executed or if dedicated disk "wiping" software was run, you're in a whole lot more trouble and you're not likely to be able to recover the data yourself.

Let's hope you just did a "quick" format of the wrong drive...

I have had good luck with recovery software software from DiskInternals. I've also used SpinRite from Gibson Research with the added benefit of bringing a failing disk back to life. Neither is free, and there are probably reputable free utilities that can reliably recover your data, but these are the ones I've used, and whether there's any merit to it or not I feel like I trust a "paid for" app over a free one. Try (UnEraser or Partition Recovery) or (SpinRite), and I'm confident you'll get your data back.

Recuva and testdisk can both do this for free.

There is no danger booting to recover your Data as long as you don't have the OS set to store files there and you don't write Data to it. It's no different than connecting it to another computer.

The only difference between a quick format and full format is that's full format does a surface scan for bad sectors. again that wouldn't really have any impact on your Data recovery chances. You have to intentionally overwrite the drive with software designed to wipe the data or write,Data after the format to cause problems
