 Posted: Sun Aug 13, 2006 10:29 am Post subject: CD Drive wont mount: bad superblock on /dev/cdrom |
 |
|
I have just finished installing my freevo box but the CD rom drive isnt working.
When i try to mount the cdrom from the console the following is printed:
| Code: |
media ~ # mount /dev/cdrom
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
|
Nothing seems to work, I have tried data dvd's etc...
My fstab has:
| Code: |
/dev/hda1 /boot ext2 noauto,noatime 1 2
/dev/hda3 / ext3 noatime 0 1
/dev/hda2 none swap sw 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,ro 0 0
/dev/hdd2 /media ext3 noatime 0 0
|
dmesg | tail gives:
| Code: |
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x50 { LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
|
My /dev/cdrom symlink shows:
| Code: |
media ~ # ls -l /dev/cdrom
lrwxrwxrwx 1 root root 3 Aug 13 09:24 /dev/cdrom -> hdc
|
Any help would be great, I know its probably something simple but I'm stuck!
Thanks
Paul |

what type of disc are you trying to mount...have you tried another disc to see if that one may be damaged?

Well it works if I mount a data cd but not a data dvd.
I have tried the data dvd on another gentoo box and that works.
Any ideas? |

UDF filesystem support in the kernel? That's assuming it is a dvd-rom, and not a cdrom as the thread title indicates.

Yup :
| Code: | #
# CD-ROM/DVD Filesystems
#
CONFIG_ISO9660_FS=y
CONFIG_JOLIET=y
# CONFIG_ZISOFS is not set
CONFIG_UDF_FS=y
CONFIG_UDF_NLS=y
|
and I have tried:
| Code: | media boot # mount -t udf /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
|
Thanks |

Same as in my first post! 
| Code: |
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x50 { LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64

sorry -- I missed that one 
according to kernel source the drive returned an error and it is described as:
| Code: |
sense_key : Sense key of the last failed packet command
|
Whatever that means. To me it looks like a problem with talking to drive. Have you tried playing with hdparm? Maybe disable/enable DMA for the mentioned drive and see what happens... What tells ?

I have the same error. I also have udf built into my kernel. When I run:
(/dev/hdb is my dvdrw drive) I get:
| Code: |
localhost mnt # hdparm /dev/hdb
/dev/hdb:
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Inappropriate ioctl for device

Well, ya. I upgraded my entire computer 
I ended up getting a new pc (upgrade to amd64). The drive used to work without any of these kinds of errors (that I had noticed, at least) so I'm pretty sure it is in good physical shape at least and that it is only a setup issue somewhere.

Did you ever solve this? I have apparently the same issue.
Thanks. |

Howdy.
I think I have the same problem 
When I burn a DVD with K3B [3.5.5], sometimes it doesn't mount at all, but works properly under Windows.
I have UDF and ISO9660 support compiled in my kernel [2.6.16-gentoo-r13].
When I'm trying to mount [with -t auto, udf or iso9660, whatever], I'm getting error messages:
| Code: | mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so |
and on dmesg:
| Code: | attempt to access beyond end of device
hdc: rw=0, want=68, limit=4
attempt to access beyond end of device
hdc: rw=0, want=1252, limit=4
attempt to access beyond end of device
hdc: rw=0, want=1028, limit=4
UDF-fs: No partition found (1) |
I'm bothered by this strange output from hdparm also:
| Code: | /dev/hdc:
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Inappropriate ioctl for device |
What's wrong?

I still don't know how to fix whatever may be wrong with the drive, although I did figure out how to burn a dvd that is readable. Have you tried the stuff I posted in this other thread?
As for the drive, I have been learning more about hdparm in an effort to have more control over its settings. The Gentoo wiki has a good hdparm guide here.
That's about all the progress I've made so far. |

Same is happening to me, too. On amd64 (if it matters). I can't read some dvd's that I've burned before on the same drive, but I can read them on a gentoo laptop without problems.
I noticed, that using dvd-r or dvd+r makes a difference. Most of the problems happen with dvd-r. And I also cant't read dvd video discs.
Here is the data about my dvd device (here are two lines for the same device from /var/log/messages):
| Code: | NEC DVD_RW ND-4550A, ATAPI CD/DVD-ROM drive
ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache, UDMA(33) |

Hey there
I am getting exactly the same error messages as described above. Has anyone found a solution?
I am running Kernel 2.6.16-suspend2-r8 on an HP dv1000 laptop (~x86)

I too am having the exact same problem. Have tried recomiling my kernel with UDF support as a module, then loading it with insmod. Didn't help. Get the same error messages as reported above. The DVD burner (Sony NEC 7170A-0B) works fine with iso9660. The DVD disk works fine on an XP box.
I really want to get this fixed so I can run X-plane on this machine. As it stands, X-plane requires that its DVD program disk be mounted as UDF.
