I have the same problem mounting recorded dvds without names. I burned them in Toast 10 in Leopard without a name & they mounted fine as a "untitled UDF volume". In Snow Leopard they will not mount. Toast still sees them & will do a disc copy, they just won't mount automatically or using disk utility.

I hope someone can find a way round this, I have nearly 400 such dvds.

All other discs mount ok.
 
cropduster,

I figured out how to mount it. You'll have to mount it manually from the command line. You'll have to first figure out which device your superdrive is under the /dev directory.

First put in a DVD that is actually mountable into the superdrive. Once it's mounted, go to terminal and type the df command and it'll show you which /dev/device it is. For me, it's /dev/disk2. Eject the DVD in the superdrive.

Now, put in the DVD that is not mountable (because it's missing a label).

Open up terminal, and type:

sudo mount_cd9660 /dev/disk2 /Volumes/CD

If the directory /Volumes/CD doesn't create, you have to create it first.


I think this was a minor oversight by the programmers. It should most likely be fixed in the next update/patch.

Hi, thanks very much, I managed to mount the DVD ok.
Only thing is I cannot unmount it however I try. I tried:

disktool -u diskXYZ
disktool -e diskXYZ
hdiutil eject /dev/diskXYZ

The disc is always busy (it shouldn't be).
Tried force eject & via disk utility, still won't eject. I'll reboot in a mo then eject it, but do you know how I can force eject discs, otherwise I will have to read them in my Linux machine or restore the time machine backup I made before installing SL until they fix this.

Thanks again for the help.
 
I am able to eject without any issues. I am doing the following:

sudo umount /Volumes/CD
sudo drutil eject

Where /Volumes/CD is the directory you mounted it to.

I hope this helps

Hi, it did help, all works ok now, thanks very much for your time.
 
Easy solution found finally

I had the same prob after upgrading to SL on my MacBook Pro 15" 2.2 Core2D.

I had already fresh reinstalled SL to no avail.

This has fixed it for me;

Goto System preferences > CDs & DVDs > When you insert a video DVD > IGNORE

good luck

Disk Utility

I've found a DVD will mount as soon as I launch disk utility.
