- | machine. They did a surface test and printed the physical and logical disk
- | information. This test didn't return a failure.

- | on) when I had the drive connected to it. That meant that sometimes the
- | system didn't boot at all. Sometimes it did boot, but then the SCSI bus
- | locked when trying to write to the drive. I want to emphasize again that
- | the other identical drive I bought did work (and that I double checked all
- | jumpers half a dozen times to make sure they were set correctly). In the
- | mean time, I have bought a third identical drive (at a different shop) and
- | this one works without problems too.
- |
- | The problem is that the shop now claims that the drive works. They want to
- | charge me for the test.
-
- Don't pay them for it. A surface test won't tell you anything about
- firmware or hardware timing problems that might show up on a different
- type of system. I'd say that they aren't very aware of scsi issues,
- if you described the problems to them this way, and they performed
- a surface test.
-
- It would help to know *exactly* what messages were being printed
- on the console, and/or put in SYSLOG, when this happened.
