By the way, I'm also wondering about the weird characters in the line
that identifies my second hard disk, an 80G Maxtor, but I don't think
they do any harm in themselves.

Things you can try:

-if there is a BIOS CHS setting for that drive, or it's set to "AUTO" turn it off (no drive present). Linux will still find the drive. Conversely if the BIOS is already set to "no drive present," set it to the correct CHS setting for that drive.

-Try a different kernel

-Test the Maxtor on a different motherboard.

-If you are ambitious, recompile the kernel and printk the drive ID string to 
see
how or why it's being corrupted, then submit a bug report or patch to the IDE guy (especially if the bug is still in the latest kernel).
