can't mount /media/cdrom0


i burned a data DVD in windows (still trying to figure out a way to back up my bloody DVD for my wife) and the data is there, but under linux i can not mount it.

Code:
cdrom: This disc doesn't have any tracks I recognize!
attempt to access beyond end of device
hda: rw=0, want=68, limit=4
isofs_fill_super: bread failed, dev=hda, iso_blknum=16, block=16
attempt to access beyond end of device
hda: rw=0, want=68, limit=4
isofs_fill_super: bread failed, dev=hda, iso_blknum=16, block=16
attempt to access beyond end of device
hda: rw=0, want=68, limit=4
isofs_fill_super: bread failed, dev=hda, iso_blknum=16, block=16
cdrom: This disc doesn't have any tracks I recognize!
attempt to access beyond end of device
hda: rw=0, want=68, limit=4
isofs_fill_super: bread failed, dev=hda, iso_blknum=16, block=16
does not matter if i try to mount it as user or with sudo. still same error in dmesg:
Code:
cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

/dev/sda5       none            swap    sw              0       0
/dev/hda        /media/cdrom0   udf,iso9660 user,noauto     0       0
/dev/scd0       /media/cdrom1   udf,iso9660 user,noauto     0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0

yup, no problem there.

the reason i burned the raw data out to the DVDs was in hopes of putting them on my Linux HDD so i could mkisofs (or what ever the exact command is, was going to google for that next) so i could hope to burn the ISO out to a dual layer DVD in hopes of it working on the set top.

Heeey...stop. So you just want to move this iso to DL DVD? You don't need to access individual files then (if it's DL DVD+-RW). Linux kernel threats it as a rewritable medium with random access so you can (first) copy entire DVD data to HD and (second) copy it back to DL DVD+-RW. The first may be done with 'dd if=/dev/your-dvd-drive of=some-temporary-file,say,-/tmp/dvd0'. If there are read errors (in the middle of DVD, not in the end), add 'conv=noerror' to the command. For second do the same, just reverse if= and of= filenames.

Btw, I'm sure there is a mkisofs 4 winblows on the Internet. Cause it's OS-independent

only with cgwyn or what ever that program is called.

still does not resolve my issue with being unable to mount a standard data DVD created in nero:

Code:
sudo mount /media/cdrom0
Password:
mount: block device /dev/hda is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hda,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

ray@debian64:~$ dmesg | tail

WTF is this junk? it is NOT a CD, it is a DVD, and yes if i put in a movie DVD it plays and even auto mounts with zero problems.
