Apologies, I should have included some of that output. I'm kinda past the
"installation" stage just now (the disk in question wasn't critical to the
OS install, and in fact the machine was installed and running for a few
days before I actually noticed it was 'missing'). Here's some dmesg
output:
sym0: <875> port 0x2000-0x20ff mem
0xc6fff000-0xc6ffffff,0xc6ffdf00-0xc6ffdfff irq 10 at device 9.0 on pci1

As you can see, there's nothing on sym0 bus 0 target 3, where the disk
physically is. I've never noted any errors at all regarding these disks,
which is why it's only now when I've gone to partition the 2 18 Gigs I've
only just noticed one missing! The controller is the on-board
Symbios-based one.
Is there any significance to the order the disks are detected and
displayed in dmesg, above?
I have another identical machine (running Linux) with two more 18.2Gs,
unfortunately it is in production so I can't play around with that and see
how it compares.
Jethro.
