"No mountable file systems" error upon attempt to mount backup dmg

I upgraded Tiger to Leopard recently. I then decided to make a backup image using Disk Utility to an external drive, before wiping my drive and reinstalling Leopard from scratch.

Now I'm unable to mount the backup image, and the error "no mountable file systems" appears when I attempt to do so. I've tried booting up with the Leopard disk and restoring the image to the drive, but that doesn't work. I've tried mounting the dmg using MacDrive in XP, but that didn't work. I've also tried using hdiutil to convert the dmg to an iso to mount in XP, and no luck there either. I've tried verifying and repairing the image file in Disk Utility, and neither worked.

I know the data's there in some form or another - because the image file is 90 GB... I just can't access it.

Is there anything I can do, or have I lost all that data?

Macbook Pro 2.4 GHz, Mac OS X (10.5.1)

I am trying to do exactly what has been written here using disk warrior to access the .DMG and disk warrior is not finding the unknown drive.

I used disk utility to create an image of my MBP, then i reinstalled 10.5.6 and boot camp. I try to load the macintosh HD.dmg file back (which is 51.9GB) and i get the no mountable file system error. I have tried opening it in finder, using Carbon Copy Cloner, Disk Warrior 4.1.1.

I see the additional "disk3" come up in disk utility when the error message comes up but i can do nothing to access my information. Can someone please help.

drag the disk image into the disk utility and open it from there. It should present the same error, but a unmounted volume should appear below the image. that's what we're after. DiskWarrior should see that unmounted drive. Repair/preview as able. remember read only or compressed images can't be written to, so preview may be your only option. Hope this helps!

Tried it... No help.

This is so frustrating.
