Thx for the info, I may just give it a shot. If it doesn't work, I'll just have another extra internal drive.
I actually intend to use this very infrequently for backing up my stuff and then putting it back on a shelf, so I'm not worried about heat. I'm done with using optical disks for storage/backup. I can't count the number of times I've had files on a backup CD/DVD become corrupt after a few years of storage. It's to the point that I have to create 2 copies of every backup disc for redundancy. Plus an HD will be much easier since just about everything will be on the same drive. Who knows how long the drive will last, but I'm betting it will be better (and easier) than using DVDs.
