About a month ago I purchased a Western Digital Caviar 640GB OEM (WD6400AAKS) from newegg to serve as a "backup drive" for my PC at home. I have it hooked up to my PC via USB (using a BlacX eSATA/USB HD Dock). WindowsXP detects the drive just fine and I formatted it, ran chkdsk (no errors), and everything appears normal. I copied some zip files to the harddrive but when I tried to open the zips, I got CRC errors. I ran a binary compare of the original file with the backup on the new drive and sure enough, they weren't identical (date/time/size were identical though).
At this point I thought maybe SATA2 drives aren't compatible with USB so I installed the drive in my newer PC in my office which has free SATA ports. Windows again detected the drive just fine. I ran chkdsk to detect any bad sectors, everything looks fine. Repartitioned/reformatted the drive again to be safe. Ran WD Diagnostic Tools which detected NO problems with the drive.
I copy over some files to the new drive and ran a binary compare.. *some* of the files were identical, the rest weren't (again all the files had same date/time/size). The weird thing is I'd run the binary compare over and over again and each time it would report different files were identical and others were not. So I've determined there is some kind of "read error" with this drive. Anyone know if this is a common problem that can be easily fixed or should I RMA this?
