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.
