I know that you said it's not termination BUT - check the
termination ;-) Check every drive in the chain has the terminators
disabled on it - modern drives are sneaky and it is very easy to leave
the terminator enable link on. I had this happen to me once - a disk
was terminated in the middle of the chain, everything worked fine
until I added another tape drive.
The other thing to check is that the drive spin up on power up. If
the drives have a delayed spin up then they may not be up & ready when
the probe comes along. Normally the amount of delay is dependent on
the scsi id so the higher numbered disks are more likely to not be ready.
