>Description:
I could mount an iso9660 file system from a CD.
Any access to the data failed. Appearently the CD is damaged.
That happens... but I wasn't able to unmount it:
# mount /dev/cd0a /mnt
# $ ls -l /mnt
ls: /mnt: Input/output error
$ su
[...]
# umount /mnt
umount: /mnt: Input/output error
# umount -f /mnt
umount: /mnt: Input/output error
# dmesg
[...]
cd0(piixide0:1:0): Check Condition on CDB: 0x28 00 00 00 00 1c 00 00 01 00
SENSE KEY: Media Error
ASC/ASCQ: L-EC Uncorrectable Error
>How-To-Repeat:
See above. Might be hard to get that specific read error from a CD.
Would be good to have some way of error injection in the disk drivers.
