That's the one that came with my Indy.

Yeah, google finds numerous problem reports - maybe ARCS knows  
something we don't (yet).
Umm, after reading your comment - I had a similar problem on macppc  
when mesh(4) didn't support synchronous transfers properly. Some IBM  
drives would start negotiating sync on their own and screw up. Many  
have jumpers labeled something like 'TIS' for 'Target Initiated Sync  
negotiation'. Mine doesn't have one but one's labeled 'reserved'.

That doesn't really sound like the problem I have right now though, we  
hang after probing the 1st drive, no matter which one it is.

have fun
Michael
