I just tried an 18Gb IBM 18ES LVD/SE disk in my SS20 but it did not work out
very well. At bootup the drive is identified correctly but it never spins up,
it merely makes a very faint chirping sound. I also checked in an Ultra-1 with
the same result. The drive was shipped with the "SE mode" jumper installed so
I did not need to change anything, the "Disable auto spin" jumper was not in-
stalled either so I had expected it to start up all by itself.

There is not anything connected to the external SCSI port at the moment, not
even a terminator, but I do not think that the terminator would make the drive
spin any more willingly. 

Sounds like I got a rotten egg, even if it was delivered in an untampered
foil wrapping without any visual signs of abuse.
