Trouble Mounting DVD/CD Drives

**jbarnes8** · 12-05-2007

Im having trouble mounting my dvd and cd-rw drives.

First of all I'm using:
Debian 2.6.23 (was using 2.6.8 before and had same problems)
CD-Writer is the master /dev/hdc
DVD is the slave /dev/hdd

EDIT: I forgot to type "-t iso9660" in this post. when i actually did try to run the commands I did include a type. I even tried using auto as a type.

Trying to mount manually i get:

Code:

mount /dev/hdd /mnt/cdrom //cdrom, cdrom0,cdrom1 - it doesn't matter
mount: block device /dev/hdd is write-protected, mounting read-only
mount: /dev/hdd: can't read superblock

Trying to mount via /etc/fstab i get

Code:

vic:/home/jeremy# mount /media/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/hdd,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

This is the same for hdc and hdd.

I have recompiled my kernel using the option "use multi mode by default" under the ATAPI/ATA/IDE sections because if you look at the help in make menuconfig it says that if i get:

Code:

hdd: command error: status=0x51 { DriveReady SeekComplete Error }
hdd: command error: error=0x50 { LastFailedSense=0x05 }

...to select that option.

As you can see, I still get that in dmesg (after recompiling):

This is dmesg after trying to mount manually:

Code:

dmesg | tail
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x50 { 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 00 00 00 01 00 00 00 00 00 00 00 "
end_request: I/O error, dev hdc, sector 0
FAT: unable to read boot sector

This is dmesg after trying to mount via fstab:

Code:

dmesg | tail hdd: command error: status=0x51 { DriveReady SeekComplete Error }
hdd: command error: error=0x50 { LastFailedSense=0x05 }
ide: failed opcode was: unknown
ATAPI device hdd:
  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 hdd, sector 64
isofs_fill_super: bread failed, dev=hdd, iso_blknum=16, block=16

Here is my /etc/fstab:

Code:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/hdb1       /               ext2    defaults,errors=remount-ro 0       1
/dev/hdb5       /home           ext2    noatime         0       2
/dev/hdb6       /usr            ext3    defaults        0       2
/dev/hda2       none            swap    sw              0       0
/dev/hdb3       none            swap    sw              0       0
/dev/hdd        /media/cdrom0   iso9660 ro,user,noauto  0       0
/dev/hdc        /media/cdrom1   iso9660 ro,user,noauto  0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0

And here is lsmod just in case:

ls /dev lists cdrom,hdc,hdd
uname -a says my new kernel is being used and there are cd's in both drives.

I can hear the drives spinning when I try to mount manually but not when I use fstab. I have tried all this under root and regular user.

Can anyone help me figure this out?

Also fdisk

Code:

fdisk /dev/hdd //or /dev/hdc
You will not be able to write the partition table.

Unable to read /dev/hdd
