hi,

does the above message mean that the cdrom (the disk, not the drive)
is defective ?
I get a lot of this messages after dd if=/dev/scd0 of=/dev/null:

scsi0 channel 0 : resetting for second half of retries.
SCSI bus is being reset for host 0 channel 0.
SCSI CD error : host 0 id 4 lun 0 return code = 18000002
Current error sr0b:00: sense key Medium Error
Additional sense indicates Random positioning error
CD-ROM I/O error: dev 0b:00, sector 843136

the bad thing is that I cannot ^C the process doing dd nor kill -9 it,
so it's stuck somewhere in the kernel. or do you have to wait for
some minutes ? (sync, df will hang from now on...)
