Help with mSD card format/mount on OS X 10.8

I picked up the KickStarter Nifty MiniDrive for my MBA (2012).  I also have a new Sandisk Ultra 64G microSD card for it. I popped it in, it mounted and worked great!  That is, until I wanted to format the drive using disk utility.

The mSD card arrived (from Amazon) in the usual FAT32 format.  I wanted to write as OS X journaled like I do all of my drives that are used for storage on the Mac. Note, this card will not be used in any cameras. The format seemed to freeze about 50% done, then it finished with errors and would not mount.

I've tried everything I can think of from within disk util and no change. I went through terminal to see if the card was mounted, nothing.  Here is the log file of my last attempt to erase/format the card on the Mac, I have tried with it in the MiniDrive, in the SanDisk provided adapter directly in the MBA and via a USB card reader.  The results are the same.
