Currently we have 2 SATA hard drives housed in removable enclosures (NTFS partitions). Each week the drive is swapped out with the other one after the backup job has completed. The files that are copied are large virtual machine files ranging from 20-100 gigs in size. We use a utility called Hotswap! to re-initialize the drive after it's physically swapped out, to ensure that Windows is aware of the current drive.
The problem i'm having is that we end up with file system corruption on these drives. The error states that "the file or directory is corrupted and unreadable". Running chkdsk seems to correct the problem, but i'd like to avoid any corruption in the first place.
My main question is how can I achieve my goal of having a hot-swappable drive backup solution without corruption (what setup worked for you i.e. controller card etc)? Also is there a way to determine what is causing this corruption?
