    0x21 original uDrive FAT
    0x22 uSD-HC support
    0x23 quicker init without uSD card, quicker init (No delays), ReadCSD command

    So no clues there... and there's no known issues.

    The status command is so FAT Controller can work out what's in the uDrive, notyhing special really

    0x80 uSD_PRESENT
    0x40 uSD has FAT partition
    0x20 uSD has RAW partition
    0x10 FAT PRotection on

    So, in this case, it's odd that the Fuji Film disk doesn't have the FAT partition being detected, but it's consistent with everything else you are seeing.

    I Don't have a disk of that brand to try, don't think I can get one from my regular supplier(s), did you buy it over the net?

    MicroDrive PmmC firmware V23 fails when V21 works?

    I have a completely repeatable problem with 2 Gb FAT micro-SD cards working fine with V21 firmware, but not with V23. My Fuji disks won't work with V23, Sandisk work with both versions. This is 100% consistent across several disks and logger modules.

    I notice that the "Get Status" command [7A] return is D0 vs 80, but can see no definition of this command in the documentation (http://www.4dsystems.com.au/downloads/microDRIVE/uDRIVE-uSD-G1/Docs/uDRIVE-COMMANDS-SET-REV4.1.pdf)

    The "list directory" function returns (multiple) NAKs with the V23 firmware.
    1. Is this a known issue?
    2. Do I have the correct latest firmware? (not easy to find on your website)
    3. Where can I find documentation for the "Get Status [7A] command?
    4. Is there a summary of the firmware changes made from V21 to V23?

    FAT controller logs included below (The Sandisk card has files on it, the Fuji one is blank). Note the 15 15 15 "Three NAK" response from the V23 module with the Fuji disk compared with the response from the V21 module (same disk in both cases).


    Thanks in advance,

    Ian
