I bought a Jaz drive two months ago, at which point I was running Linux
2.0.25 on Redhat 4.0. I'd had tremendous trouble because my Adaptec
2940UW didn't like my SCSI cables, but after replacing them, everything
ran fine. Processes accessing a sleeping Jaz drive would hang, but once
the bugger was up to speed, things ran fine. The only program that has
had trouble with a sleeping Jaz drive has been e2fsck, which would give me
the "Are you REALLY sure there's something on that device" error message
once the drive has spun up, but the e2fs programs on my machine -- and the
kernel (I'm still running 2.0.25) -- need to be upgraded.
