I hate to grave dig an old thread, but I just got my Wii U... and tested out a USB flash drive. Interestingly enough, after it gets formatted by the Wii U, it shows as completely unallocated space in GParted, which is usually able to detect all kinds of fancy filesystems.
In fact, GParted would probably let me make a partition on the drive (that's different than formatting the drive, as you aren't rewriting the MBR at all)... but that would obviously wipe out the Wii U portion of it.
Does anyone know how exactly it formats drives? I know for example, the Xbox 360 uses FATX which is just a bunch of files stored on an ordinary FAT32 partition so you CAN only allocate part of the space and use the rest normally. I don't think the PS3 supports external drives for storage so I'm not sure on that one.
