[Solved] Can't mount /dev/cdrom

[amightywind]

I went to rip a cd today and found that my cd wouldn't mount. I have a Sony CDRW/DVD combo drive. It has recently stopped working. I don't know if some kernel config variables changed. My kernel version is 2.6.18-gentoo-r4. /dev/cdrom exists:

# ls cdrom
lrwxrwxrwx 1 root root 3 Dec 14 18:53 cdrom -> hdc
# ls hdc
brw-rw---- 1 root cdrom 22, 0 Dec 14 18:53 hdc

I am using linux-2.6.18-gentoo-r4. Here is the failed mount:

# mount -t iso9660 /dev/cdrom /mnt/cdrom
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Here is my fstab
/dev/cdrom /mnt/cdrom iso9660 user,noauto,ro 0 0

Here is the end of my dmesg:

hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
ATAPI device hdc:
Error: Illegal request -- (Sense key=0x05)
Illegal mode for this track or incompatible medium -- (asc=0x64, ascq=0x00)
The failed "Read 10" packet command was:
"28 00 00 00 00 10 00 00 01 00 00 00 00 00 00 00 "
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16

Here are the config settings:

#

#
# CONFIG_BLK_DEV_IDE_SATA is not set
# CONFIG_BLK_DEV_HD_IDE is not set
CONFIG_BLK_DEV_IDEDISK=y

what does ls -la /dev/cdrom say? permissions wise?

[amightywind]

The listings of the permissions are at the top of the first message. Thanks.

Did you test a different CD first?

What is the output of:

[amightywind]

I did try another cd. My first thought was that the new one was DRM'ed. What does *CODEPAGE* control?

$ cd /usr/src/linux
$ grep CODEPAGE .config

The error could indicate, that you try to mount an audio cd, which isn't possible. Did you ?

This got me looking elsewhere. My problem is gnome configuration. I am using new gnome programs in an older environment [xfce] that doesn't work well with them yet. Thanks.
