Hmm. I will have to investigate this drive further, are there many reports
of UniDisk 3.5's just...dying? You know, like common problems (like the
cap blowing on a Disk ][, etc).

Yeah, I knew about the different sizing but I never can remember which
letter goes where. But then, that was someone else saying that. How
exactly does the size coordinate with the letter?

Hmm. I guess I'll have to keep my eye out for one then.

Oh, and thanks
