Still trying to solve that problem on my SB1000. Still working fine using 
the external 73 GB SCSI drive though. The internal 73 GB FCAL drive 
doesn't show up at all when I run 'format'. Bizarre. ATM I don't have any 
other FCAL drives to try for comparison so it might just be a drive 
firmware issue since the OBP sees it.

Depending what brand they are... If the drives happen to be Seagate's then 
some of those tend to re-calibrate every so often and that action results 
in a noticable sound a bit like a clunk. Seems to be specific to the 
Cheetah series drives based on my experience.
