i got this from some small shop a while back and when i was at macworld recently i saw the company that made the unit
but i don't know the name of the company and i no longer have the mac drivers that came with the unit (the drivers were on a floppy!)
i thought that the drive would be automactically seen by os x but that is not the case
here is a link to a picture from newegg:
it looks like this
the hdd that i have in it is a 9.5 mm ibm
