Post install Fedora 15 - cannot mount DVD backup


I just upgraded from Fedora F11 to F15. Before making this transition, I backed up my system using my Mac's DVD burn hardware and tested the disk on my F11 system. Ok.

After F15 install, the DVD backup won't mount. I've tested a generic DVD from a tech book and this will mount. Ok.

For my backup I tried to mount manually with, Command:
Code:
# mount -t hfsplus /dev/dvd /media
This results in generic error which instructs me to check
Code:
# dmsg | tail
hfs: unable to find HFS+ superblock
What else can I do? hfs-tools is installed. I don't know how to go about troubleshooting this.

Hi there,

When you insert normal DVD you said it works OK. Did you use the same command to mount the normal DVD or it got automounted.

Code:
hfs: unable to find HFS+ superblock
Is this the message that you get when you type the command
Code:
mount -t hfsplus /dev/dvd /media
Did you try running:
Code:
 mount -t hfsplus /dev/cdrom /media
or just
Code:
 mount /dev/cdrom /media

The actual output is:
Code:
 # mount -t hfsplus /dev/dvd /media

> 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

Did you try using the command without mentioning the partition type as suggested in my previous post?

Code:
 mount /dev/cdrom /media
Paste the output of ls -l /dev

T3RM1NVT0R: I didn't read it as a suggestion, but as a question (did you try A or B?). hhaha.

Code:
# mount /dev/cdrom /media
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: you must specify the filesystem type
Code:
[... dev]# ls -al

for a normal everyday dvd it should not be in apples hard drive format HFS

what happens if you do not use the type command
Code:
su -
mkdir /media/dvd
mount /dev/dvd /media/dvd

# mount /dev/cdrom /media
mount: block device /dev/sr0 is write-protected, mounting read-only (This message appears to be normal)
mount: you must specify the filesystem type (Not sure why this message is coming up)
From the output it appears that it got mounted. Are you able to see the contents of the DVD?

@John VV: I am able to make a directory in /media; however, the same error messages repeat. The disk is not mounted.

I understand the philosophy of using native formats and open formats. Truly the data is not lost. Im more concerned that this disk mounted correctly on my F11 install. I am in that phase, after a new install, when I have yet to discover if it was successful.
