Blank install and I cannot mounting cds/dvds

After installing and patching up to Duke, I am consistently unable to mount DVD's or audio CD's.

The message I get from the mount command is always:

# 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

a dmesg | tail yields:

end_request: I/O error, dev sr0, sector 64
isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

I can mount data CD's, for instance it will easily/quickly mount the arch cd with a mount /dev/cdrom
However, it will not mount anything that is ISO9660 or UFS.

What am I forgetting to do?

Re: Blank install and I cannot mounting cds/dvds

perhaps try explicitly telling mount where you want the drive mounted to:

example:

mount /dev/cdrom /media/cdrom

just to see if taht works

Re: Blank install and I cannot mounting cds/dvds

You could try "ls -l /dev/cdrom" or "ls -l /dev/dvd to get some on valid dev's

Also you might need two different entries in fstab, one for cd's and one for dvd's, for example...

/dev/cdrom      /mnt/cd         iso9660   ro,user,noauto,unhide   0      0
/dev/dvd        /mnt/dvd        udf       ro,user,noauto,unhide   0      0

I like to mount under /mnt instead of /media and I think I had to create the dirs cd and dvd under /mnt

Re: Blank install and I cannot mounting cds/dvds

I have tried explicitly telling mount where to mount it to, no luck.

Also, I am certain my fstab has both of those entries.

I haven't tried an "ls -l /dev/cdrom" However, I'm pretty sure I have the correct dev as a "mount /dev/cdrom" works perfectly on the Arch iso.

edit: I should mention that the directories in mount do exist, i.e., a blank /mnt/cdrom and a /mnt/dvd both exist to mount to.

You don't mount audio CD's


I made it long
as I lacked the time to make it short...

Re: Blank install and I cannot mounting cds/dvds

Audio CDs don't have a file system that can be read conventionally, they like contain a bunch of sound samples that can be converted into a readable format, hence ripping the cd to disk. Your media player should be able to play audio cd's if it's set up to look for the correct cdrom device. I would experiment with some data discs to verify that your cdrom drive/drives are set up correctly, and can be mounted and unmounted.

Re: Blank install and I cannot mounting cds/dvds

I solved that problem changing my /etc/fstab lines from this:

/dev/cdrom             /mnt/cd   iso9660   ro,user,noauto,unhide   0      0
/dev/dvd               /mnt/dvd  udf       ro,user,noauto,unhide   0      0

to this:

/dev/cdrom             /mnt/cd   auto   ro,user,noauto,unhide   0      0
/dev/dvd               /mnt/dvd  auto       ro,user,noauto,unhide   0      0

Maybe this can help you too.
