I have the Western Digital VelociRaptor 10k drive SATA. Itís about 9 months old now. On three occasions I have noticed quite large chunks of data just disappear off my hard drive. Just now I noticed 200 consecutive pictures disappeared out of one of my folders. I tried to use a data recovery program to get them back but there was no trace of them. Does anyone have any idea what might be going on? I have never received any type of operational error related to my hard drive and I donít have any random unexplained crashes. Is there a program that can test the drive for data retention? If it matters at all, my hard drive is often fragmented for I use a download accelerator that breaks files up into pieces and I often upload large amounts of data to my drive at once. I highly doubt thatís relevant though.

I don't know of any program that can test for data retention...but I would run the appropriate WD diagnostic (long test) on that drive.

What Diagnostic? That program you provided is just some cheasy freeware program that helps noobs install a hard drive, view drive info, or partition the drive. It does not appear to have any other function and there is no listing of any diagnostic program in the 5 page long user manual for the program.
