Question Mounting a DVD RW in Ubuntu 11.04


Okay, just FYI. I've been googling this issue for two hours now with no success so I'm going to post a question and hope I don't get flamed.

This is going to sound a little ridiculous. I burned a few DVDRW on my mac machine at work. They're data dvds containing .avi files.

I get home only to discover my Vista machine doesn't like the discs. No problem, I boot up my Linux partition only to discover that I can't seem to mount these DVDs under linux either.

I quickly determine that I need to use hmount, instead of mount, so I use these commands:
$ sudo hmount /dev/sr0 /mnt
/dev/sr0: contains 1 HFS partition
hmount: /dev/sr0: not a Macintosh HFS volume (Invalid argument)

$ dmesg
[ 7182.485003] hfs: can't find a HFS filesystem on dev sr0.
I know I'm missing something easy here. Can anyone help?

Is isn't for sure that the filesystems on the disks are HFS, maybe it is UDF although it isn't going right with the windows try you have done

So try with mount -t udf /youDrive /mnt.
Or try to sustitude the udf with hfs.

So I did try that earlier, but here's the output:
$ sudo mount -t udf /dev/sr0 /mnt

mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

$ dmesg | tail
[12312.328478] UDF-fs: No anchor found
[12312.328489] UDF-fs: No partition found (1)
[12338.027617] UDF-fs: No anchor found
[12338.027624] UDF-fs: No partition found (1)


$ sudo mount -t hfs /dev/sr0 /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error

dmesg | tail or so

$ dmesg | tail

This is kinda a stab in the dark, but you might try using dd to get a copy of the disk in iso format, then use mount to mount it with the loop option.

Though you may have to mount it before you can use dd. I don't know, just a thought.

i think it is a great idea, what you need to do is :

Code:
dd if=/dev/sr0 of=/whatever.iso
then mount that image with the

Code:
mount -o loop
look in the man page of dd in case you need more options.
