The enclosure I was hoping to use is an OWC Neptune.
I now have a variety of bare drives in storage. I buy a complete backup drive and when it's full, I replace it with a bare drive. The Neptune came with a 40 gig originally, and since then it's had 4 different drives in it, the largest of which is the 160 gig. These larger drives just might hit the limit, and if they do I'll buy a large external drive and start again.
Hey Kris, do you still have that large steel SCSI box that we both bought way back when? Did you ever alter it somehow? I like the idea of using it, seeing it had accommodations for 2 drives. Maybe a scsi to firewire adaptor would work, if there is such a thing?
