[HLUG] HD problem

[Graham Cole]

thanks Andrew for the several ideas below. In the first place the
warning was given during the boot process and said:
SMART failure predicted on Primary Master:
Warning:Immediately back-up your data and replace your hard disk drive.
A failure may be imminent.

I guess I could have booted in recovery mode and saved all of my home
folder contents to disk. I've never done a save to disk because I had no
disk writer before now, so I decided to install a new disk with a new
system, Ubuntu 7.04, Feisty Fawn.

Now I can't find access to the second, suspect disc which shows up as
second master in the BIOS although I set the jumper to slave position.
In /var/log/messages I don't see the disk, presumably because it's not
part of the booted system. Here's an extract from that file:

It's odd that hdc appears as the CD drive! The only mention of hdb is
"hdb:pio" which I don't understand.

Any ideas welcome....
