eewwe..

ok .. no prob. If you have been working fine with this HD up until now .. I would first run some general maintenance on the drives (specially that big one)

before you start taking things apart or replacing drives.

Run scandisk / disk clean up / defrag / etc. on the drive first ... (PLEASE ONE APPLICATION AT A TIME) cant tell you how many times students come up here and have crashed drives.

Also might want to restructure the media HD into different partitions .. its a bit cleaner and easier to maintain
