I have a Quantum XP2160 and a Seagate 1050 in my 3000. Both function, but have significant bearing whine, and I have no idea how many hours are on each. So, I know my scsi subsystem and termination are fine. I’m going to pull a scsi2sd v5.2 from a Quadra 700 and try that, to see if I get the same errors. I used the RZ40 as the inquiry string, and matched the sector count, to make SRM happy. I have real RZ25s and RZ26es, but they are quite small. Most of my modern scsi disks are 10 and 15k U320s, and not a good choice for heat constrained enclosures like the 3000. Not to mention that 300gb is just silly for Digital UNIX. - Alex
