I recently bought a new PC case and transferred all of my PC hardware into it. The only hardware modification was the addition of two identical ram modules.

The entire process went smoothly, and everything worked and booted as before. The only side-effect I found when accessing one my of file-based hidden truecrypt volumes shortly there after. Some of the files in the volume - NOT all - seemed to be entirely corrupted. The directory and file names are garbled characters, but a few of the directories in the same volume appear and function normally. Also, all files in the non-hidden tc volume were still intact.

Is this not weird? The only other real change I could think of would be that the hard drives were connected to different SATA ports on the mobo. I really don't know how the truecrypt encryption works well enough to know what could cause this...and the fact that not all the files were corrupted makes it more bizarre still.

So, first off (and I'm not too hopeful on this point), would it be possible to restore these files? I had a backup of most, but not all of the files involved.

Other than that I'm just curious how this happened and how I can prevent it next time.

Thanks!
