I have a SCSI castlewood ORB drive connected internally to an adaptec 2940
UW. It works fine under windows as a Removeable SCSI device, but under
linux it only works as a fixed drive. If the system is started with out a
disk in the drive, the boot sequence gives:
(scsi0:0:6:0) Synchronous at 10.0 Mbyte/sec, offset 8.

Probably an unrecoverable SCSI bus or device hang.

and then the machine hangs. If a disk is present on boot up the disk is
detected correctly:
(scsi0:0:6:0) Synchronous at 10.0 Mbyte/sec, offset 8.

and the disk sdc5 works fine as a fixed drive. When the disk is ejected,
the machine starts hitting the SCSI bus real hard and grinds the system to
a halt.
The device is an Ultra Wide scsi device connected to an adaptec 2940UW,
internally. The linux kernel version is 2.2.16. There is a bit in the
orb's firmware that toggels between fixed mode and removeable mode. I
set the bit to removeable, and windows accepts it as a removeable
drive, but linux does not. Does anyone have any ideas as to why the scsi
drivers get upset over having an empty removeable Orb drive?
thanks
