My apologies; Outlook Express (/gasp) isn't the most condusive to mailing list replies.

Well, you didn't mention that it's disappeared from the system
(as opposed to the raid array only).  And no, I for one don't
know how to re-add it - there are numerous reasons why it may
had disappeared, and it may be of different kinds of drive too
(like, SCSI or SATA).  Some cases can be handled (like, sending
"bus reset" and "start unit" commands followed by bus rescan
sometimes helps).  But it's safer to just reboot anyway (cold
reboot, with power off).

It's a SCSI drive; in's a Dell 220F enclosure connected via a QLA2200 adapter. I've pulled the bad disk (tho not 'yellow' at the hardware level; and re-inserted it -- but to no avail. It did cause a reset; but the device remains 'disabled'.
