I don't know if anybody is interested, but I pulled the HD out of the MyGIG, connected it to a laptop and booted with Knoppix Linux. I looked at the partition structure with fdisk and got the filesystem info below. I knew they were using the QNX operating system, but was hoping they were using an ext2 or ext3 filesystem. This appears to not be the case. I took a snapshot of the image on the drive, and am going to build a linux live CD that will read the qnx filesystem type so I can look around at the structure of it. I will post more info when I do.
