I've replaced the cable, no joy. I've changed the jumpers to give it
ID 1, connected it to an Adaptec 7899 scsi controller in another box
and it shows up with ID 1. I formatted it, put it back on the Adaptec
2100S - it shows up as 'Missing component'.

The failed drive shows up fine - as Failed. As far as I can see
there's nothing wrong with the drive itself, I've verified it twice
and formatted it.

The Adaptec knowledge base has:
"   	Replacing failed drive - Array includes a missing member and
cannot rebuild"
"Ensure that the new drive inserted in the system has a unique SCSI ID
and thus does not conflict with any of the present drives or the RAID
controller (SCSI ID 7). Even if the new drive does not appear as a
member of the array, ensure that it is detected as a single
independent drive."

In this case the new drive isn't being detected at all.

Any ideas?
