    If I understand correctly, the TouchPad's 'USB drive' (/dev/mapper/store-media) starts out as a regular FAT32
    partition, but then the partition table gets zeroed-out (maybe by LVM2?).

    Could you point me to a copy of the original 512-byte boot-record, or the partition table, or give the C:H:S
    values?

    I'm trying to undelete a folder on the USB drive using <testdisk>, and as you can imagine, it's flummoxed by the missing partition info; maybe the original values will work. Incidentally, why is this info removed?

    Thanks,

    Here you go. Rename the file without the .txt.

    Well, that's another 'neutered' MBR, with a zeroed-out partition table; I assume
    that at some point during development, /dev/mapper/store-media had an intact MBR with
    partition info (something besides null characters in the 1be thru 1fd positions), could
    you point me to that?

    Or, does /dev/mapper/store-media possibly have other MBRs stored on the TP? I've
    noticed that /dev/mmcblk0, /dev/mmcblk0p1 and /dev/mmcblk0p4 have intact MBRs (the first
    two are bootable), while none of the other 12 mmcblk0 partitions have anything resembling
    a MBR - could /dev/mapper/store-media be related to one of those three, or is that an
    unrelated subsystem?

    Thanks,
