I've got the same drive.  Attached to a 1542B it works fine.  Attached 
to a 2940U the filesystem is corrupted within minutes.  Reducing the 
bus speed to 5 MB/S and turning off tagged queueing fixes the problem.  
W/O the patch, it claims to be capable of 254 device openings -- I 
would think that's a bit high for an old drive.

Anyhow, I replaced the CFP1080S, which itself replaced a dead Quantum 
drive, with a brand new 4 GB Seagate -- replacing a 2 GB drive with a 1 
GB drive caused a host of other problems not related to problem 
discussed here.   :)
