Sorry, I should have been more clear.
The three SCSI drives are in a raid 5 and raid 1 for the /boot.
The USB drive is a 250GB drive thats sole purpose is for samba sharing
that doesn't require backups (for example, freely distributable programs
from the net)

My concern isn't about removal and insertion of the disk on the running
OS, its that sometimes it may be present on bootup, and other times it may
not. So therefore the SCSI drives will be assigned different letters if
the usb drive is not present, which would degrade the array, as they would
now be sda, b and c, and not sdb, c and d.
On looking at your udev rules, could I apply this to both udev on the OS,
and udev on initrd, and instead of the USB drive being assigned /dev/sda,
it will be assigned /dev/usbdisk, and the other SCSI disks would be
assigned /dev/sda, b and c?
Thanks again.
Scott
