Windows 7: BitLocker Has Damaged Some Files

BitLocker Has Damaged Some Files

So here is what happened, in steps:

1) Started BitLocker encryption on drive E:
2) Power failure interrupts the process around %17
3) Could neither access drive E: nor continue BitLocker encryption
4) After some search, found out that BitLocker Repair Tool can recover a drive to "an empty output volume of equal or larger size than the BitLocker-protected drive"
https://technet.microsoft.com/en-us/...=ws.10%29.aspx
5) Did that. After the decryption process, used "chkdsk /f", to check for and fix errors.
6) After that, formatted drive E: and re-copied its content back in
7) Found out the next day that some files are not working. Text documents have scrambled symbols in them, for example. Rar, pdf, iso, jpg, doc.. All kinds of files are affected.


Interestingly, the same files in multiple folders within the drive do not work in any of the locations.

I did a loooooong search, but all I could find was thousands of posts everywhere on "How To Recover A File From A Damaged Drive".
But I do have the files. They are already "recovered".
Still, tried a bunch of recovery tools, even though I already knew that it was futile, since:

a) I had already copied the content of the drive in question back in it.
b) It is not that the files are missing. They somehow remained "scrambled", I believe. They don't need to be recovered. They need to be "repaired", maybe, don't know how, but with the "BitLocker Recovery Key" file that I still have?

Any suggestions?

Bitlocker can not be interrupted, but more importantly, there`s no reason to use it.

First of all, thanks for taking the time to read my post. Any and all help is welcome.

You can see above that I never said "Bitlocker was interrupted".

"1) Started BitLocker encryption on drive E:
2) Power failure interrupts the process around %17"

The ENCRYPTION PROCESS was interrupted due to a power failure in the electricity grid of the whole darn neighborhood.

As to the more important part: you're right, perhaps there really isn't any reason to use it.

However, since I DID use it, and encountered this problem, and couldn't find a solution myself; I find it most sensible to ask Win7 GURUs like yourself for their opinion.

I do not believe there is a way to repair the corrupted files, unfortunately.

The best recovery for a situation like yours is to replace the file from your backup.
I have always used an uninterruptable power supply (UPS) for my system to prevent power problems from effecting my system.
