CD/DVD-ROM drives stopped working?

A very strange thing has just happened, and I can't think what I might have changed to make this happen.

Mandriva has stopped mounting conventional CDs. It doesn't automatically mount them when they are inserted, and throws up the following error when I tell it to do this:

Quote:

[Error - kio_media_mountehelper]
mount: wrong fs type, bad option, bad superblock on /dev/hdb,

missing codepage or other error

In some cases useful info is found in syslog - try

dmesg|tail or so

Please check that the disk is inserted correctly.

This seems to happen with my Mandriva installation CDs and my Knoppix CD if I try to mount it. I first noticed it just now when I tried to install some new software packages and it wouldn't recognise CD 2. I have rebooted, nothing changed. This is not a hardware fault, as I can boot into Knoppix and the Mandriva installer fine.
Also, I can play DVDs with Kaffeine with no problem.

I have two CD drives, one is a DVD/CD-ROM, the other is a CD-RW.

Here's the result of the dmesg|tail command:

Code:

Those last two appear to be to do with the error, though I don't understand what they mean.

I have tried "upgrading" Mandriva, with no luck at all. I don't have any idea where to go from here
