Missing files aftrer driver power state failure

#1 Post by iNoU » 18 Nov 2014, 20:48

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 powered 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 system suffered a driver power state failure and shutdown.

When I booted it up again I was stupid enough to not check the drive immediately and instead went and uninstalled some Windows features 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. It says I have 226 GB of free instead of the 10 GB it actually has. Before the transfer it was something like 380 GB free. So a lot of data is missing.

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 advice on how to fix this would be greatly appreciated. Thanks!

The drive passed both the SMART status quick test and extended test in the WD Data Lifeguard Diagnostic tool. Windows disc Error checking tool says no errors found, but Test Disk gave me "Filesystem seems damaged" message. Here's the log file below.

Please refer to the documentation found here
http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step

If that does not work, then you can try to recover the files that you need from the disk and then reformat the disk and repartition.
