After chkdsk on ext. drive : corrupted .exe files, jpegs, pdf's etc...
So here is the history of the problem,
I am on Windows 7 pro running on a Sandisk Extreme 240go. I just had a RAID 5 failure (one disk
failed, that was a 4x 4TB internal sata setup). After the fail, my data was still accessible, so I
decided to back it up on seperate disks (2TB flavor). I rebuildt the RAID array differently cause
RAID 5 option via Intel Rapid Storage kept failing, so I made 2x brand new RAID 1 to get 2x 4TB
backup storage. Well, the build process went well, no issues so far.
But when I plugged my backups (2TB ones) via external docking, these drives went suddenly
corrupted and inaccessible... I ran chkdsk on the 2TB's backups and somehow it fixed quite alot of
« problems ». So far so good... Drives can be accessible again. I navigate inside the disk to check
the integrity and I realize this : all my jpegs, pdf, software .exe, and Premiere Pro projects showed
up corrupted, impossible to open them, everything corrupted... except my video files (which
fortunally represents 90% of my backup). But impossible to open my «very important » Premiere
Pro projects, my jpegs and my pdf's. This only happened in my backup drives. Other drives are
simply fine with such files.
I decided to run a virus scan on the backup drives, and Norton found this : « W32 changeup »
associated with buebud.exe. It said it fixed the problem, but I still can't access my files !
I now just wonder if chkdsk did not totally messed up the backup drives. And I also wonder why
my video files are not affected by this problem.
I am quite desperate.... Can someone help me, please ?
