I have two drives, a dvd+rw and a cd-rom, and neither will mount a cd. If I try to just open the icon on the desktop for either device when a cd is in either one, I get the following:

/dev/hdd: Input/output error
mount: /dev/hdd: can't read superblock

(and hdc for the other)

This also happens when I try to mount either in the command line. I've tried rebooting a few times and it's still doing this. I'm running Mandrake 10.1.

Thanks in advance.

**edit** here's what I got from a dmesg|tail:

hdd: command error: status=0x51 { DriveReady SeekComplete Error }
hdd: command error: error=0x54
end_request: I/O error, dev hdd, sector 68
Buffer I/O error on device hdd, logical block 17
cdrom: hdd: mmc-3 profile capable, current profile: 8h
hdd: command error: status=0x51 { DriveReady SeekComplete Error }
hdd: command error: error=0x54
end_request: I/O error, dev hdd, sector 0
FAT: unable to read boot sector

And to make it even stranger, it'll play in KsCD and find the names of the songs, the band name, and the CD.
