Dust Storm

Chkdsk showed nothing wrong with the Harddrive. It's an internal 2Tb Western Digital that's only about 3 months old. I wouldn't think Defraggler would do something like this either, but the last modified time and date corresponds directly with the last time I ran Defraggler on the drive.

All the files that got defragmented that were an MP4 are now corrupt on a harddrive I use to store recorded gameplay footage. Anything that was simply moved is still ok, but if it was defragged, it's gone. Thankfully, most of them are up on YouTube, but there are some I can't get back and have lost. Doubt that there's anything I can do, but this is pretty bad for a defrag program to corrupt files.
