Software :: DMG Of Linux RAID Will Not Mount

I had a 1 TB Western Digital MyBook World (first edition with the blue rings) that failed. I was able to take apart the drive and get it spinning again by placing it in the freezer. Unfortunately, it would not mount using a USB adapter or the NAS enclosure it came with. I was finally able to get Data Rescue 3 to see it using the USB adapter. At that point, I used the software to make a clone to a DMG on a new drive. Apparently, the drive was originally a Linux RAID (without mirrors), and that's what the DMG is.

So, there are four volumes under the one DMG. I think I need only the fourth one though. Unfortunately, I cannot get the DMG to mount. I've tried DiskImageMouter, Disk Utilities, Burn, and Springy. Every single one of them tells me that there's no mountable system. Disk Utilities can see the DMG and its four volumes. I have also tried to mount it in Linux (Ubuntu) via Parallels Desktop. Is there anything I can do to salvage my files, preferably with the same folder structure. So far, I can still access the drive itself through the USB adapter, if that helps any.
