This disc was a huge pain in the butt. I already have one ATA drive in
the machine (Ubuntu root, Windows partition) and two SATA drives. My
motherboard (ASUS A8V delux) has two SATA controlers, each with two
ports. The existing drives were plugged into different controllers.
Sometime in the past I think I had a couple SATA drives plugged into
the same controller - no reason for the change. I bought a new Western
Digital 500 GB SATA and plugged it into one of the remaining ports
(top controller - whatever that is). When I restarted Ubuntu it wasn't
recognised. I tried it with a live CD of Ubuntu, Windows XP and
Partition Magic - nothing worked. I then disconnected the other two
SATA drives - plugged it into the other port on the same controller
(ie where an old disc has been) and tried it all again. Still no luck.
Then I plugged it into a port on the other controller (bottom). If I
remember correctly it didn't show up in Ubuntu, but it DID in
Partition Magic CD (Windows program). So THAT is how I formatted it
(for ext3). After that I plugged the old SATA drives back where they
were before, kept the new on on the bottom controller and everything
showed up just fine in Ubuntu.

I have never had any problems like this with setting up a new hard
drive before. I don't know what or why it happened like this. I
suspect that maybe the top controller can only be set up as RAID or
something like that.

Now that you point that stuff out I guess so. I will use use cfdisc to
re-create the filesystem and see if I get a UUID out of that.

Thanks for your feedback
