Missing files aftrer driver power state failure.

[IcyEyes]

I recently quick formatted a Western Digital Blue WD6400AAKS 640GB hard drive and installed Windows 8.1 64x on it. I then remove the drive from it's PC and placed inside another PC so I could transfer some backed up files to it more quickly. After transferring the files over the drive had about 10 GB of free space left. I then placed the drive back into the original PC again and power it on. When I opened file explorer it showed the drive still having the same amount of free space that it had before the transfer, but a progress bar at the top of Explorer told me that Windows was currently updating the file index to reflect the newly transferred files.

However, right before it finished updating the file index, the system suffered a driver power state failure. When I booted it up again after the failure I was stupid enough to not check the drive immediately and instead went and uninstalled some Windows features first and moved some files around. After this I went to open another folder I was notified that it was inaccessible due to corruption, and when I looked at the drive more closely I realized a folder was missing and the stated amount of free space was less, but still inaccurate. I ran windows disc error checking and it told me the drive needed to be repaired. So I restarted the computer, however, Windows features were scheduled to be uninstalled before the disk repair program had a chance to run. The disc repair process did restore some of the files and fix the folder corruption, but the most important folder was still missing and the stated free space was still inaccurate.

I placed the drive back in my other computer and ran Recuva set to deep scan, it found quite a few recoverable files on the drive with unknown original locations, but the most important files are still nowhere to be seen. Any ideas on what else I might try to fix the corrupted file index or recover the particular files I'm looking for?

Thanks!

did you find the solution?

you should of pulled it out of your computer and tried to fix it or recover files before windows made changes to the disk overwriting the data, I would guess it is gone.

Something like zero assumption recovery or testdisk might work if they are not overwriten?
