From that info i can see you have a 2gb micro SD and you are running the original sprint 2.08 rom version.
I have used pdocread to dump roms, you have to use special syntax for the sector size and use the windows read method. You can take a look at the info i posted on the FTP here:

The problem is that you still can't write data to the mogul with pdocwrite (obvious next step) with any of the syntax variations i have tried. Even if you could it would be quite dangerous as there is currently no way to repair bad NAND blocks on this device.
Oh and Xtreme, as for the bricking it was just to say the offer to test to that extreme was appreciated there really isn't a need for that now though, we still need lots more research.
