"hdb: driver not present"

[Jonathan Melhuish <lists@netacclaim.co.uk>]

After having recently installed Debian 3.0 over Mandrake, I'm trying to 
get all my hardware working again :-(

Although the boot messages initially correctly identify all 4 drives 
(two hard drives, CD-RW, CD-ROM), it seems only the primary hard disk is 
usable.  During boot, I noticed it say "mod-probe: can't locate module 
ide-disk" followed by "hdb: driver not present".  The primary disk is a 
Maxtor, the secondary a Seagate, if that's relevant.  Both were working 
fine under Mandrake with no further configuration.

I've tried a bit of googling (unsuccesfully) but, having never come 
across such a problem before, haven't really got any ideas :-(

Can anybody help?

Cheers,

Jon
