wierd boot message about cdrom...

[rich <rehartma@artsci.wustl.edu>]

Howdy all,

I was just browsing through my boot messages when I noticed this string
of text that I'm not sure I've seen before (right at the end of the boot
messages)...

.

.
VFS: Disk change detected on device ide1(22,0)
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
end_request: I/O error, dev 16:00 (hdc), sector 64
ATAPI device hdc:
  Error: Illegal request -- (Sense key=0x05)

ascq=0x00)
isofs_read_super: bread failed, dev=16:00, iso_blknum=16, block=32

Does anyone know if this is bad, what it means, and/or how to fix it?

Thanks in advance,

Rich
