 Posted: Sun May 08, 2005 4:45 pm Post subject: Can't mount cdrom |
 |
|
My cdrom drive, for some reason, is unmountable.
| Code: | # mount /dev/cdroms/cdrom0 /mnt/cdrom/
mount: /dev/cdroms/cdrom0 is not a valid block device
|
This has been happening since I first installed the system a few weeks ago and is quite an inconvenience. I have found that the drive is also not mentioned in the dmesg output. Another drive (a 160GB HD) on the same IDE bus works just fine and the cd drive works perfectly fine in other operating system (windows, linux livecd's, openBSD). I don't really know where to start with addressing this problem. I've played with the BIOS settings for the controller and have reconfigured the kernel in enough ways to kill a man but with no luck. Any ideas? The drive is an NEC-2500A and the kernel is 2.6.11-r6. Thanks. |

this is more likely to be the order that you have put the disks in has messed things up. Do a few things, firstly, have a look in your BIOS and see if the CDROM is mentioned and where.
then give us the output of and the output of

cdrom exists as the seconday master in the BIOS.
ls /dev/cdroms gives:
| Code: | # ls /dev/cdroms
cdrom0
|
and cat /etc/fstab gives
| Code: | # /etc/fstab: static file system information.

# noatime turns off atimes for increased performance (atimes normally aren't

# switch between notail and tail freely.
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hda1 /boot ext2 noauto,noatime 1 1
/dev/hda3 / xfs noatime 0 0
/dev/hda2 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
/dev/hdd1 /mnt/200 ntfs noatime 0 0
/dev/hdb1 /mnt/160 ntfs noatime 0 0
/dev/hde1 /mnt/80 ntfs noatime 0 0
/dev/hdf1 /mnt/81 ntfs noatime 0 0
# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs defaults 0 0

Nothing appears out of the ordinary (except all of those damn NTFS partitions) in either. |
