    Hey there,

    I recently found a cheap Dreamcast to install my USB GDROM board (I didn't want to gut my main DC). The installation went great and I am able to get to the user interface, but my games won't load. I've dumped all of my games using Dreamshell and a Dreamcast SD Adapter., are these dumps compatible with the USB GDROM board?

    Thank you

    There is a thread for all things USBGDrom. As far as your issue there are a couple things to check; Is the drive formated fat32 with 64k clusters, have you updated to the most recent firmware. Can your GDI files be loaded from dreamshell?

    The games that are compatible with Dreamshell, yes, they will load. I formatted a small 8GB SD card with Windows to be on Fat32, will that give me 64k clusters or should I try formatting with guiformat ?

    http://3do-renovation.ru/fat32format.rar this is the tool that Dr. MNEMO suggests to use. Guiformat might also work. Give this a go, sometime SD card adaptors have issues as well, if you have a USB thumb drive that might work better.

    You were spot on, it was my nice Sandisk card reader that was the issue. I plugged in a cheap generic card reader that I got for free and that one works just fine. Thanks

    Can someone please assist???

    My USB GD-ROM arrived and I'm able to play CDI and GDI's just fine from *USB STICK*.

    However, when I plug in my USB drive (FAT32, 64K clusters), I keep getting a "no FAT32 partition found" error. I have tried the Fat32formatter on this thread and even used the newer version (guiformat). I have tried the following hard drive combinations but still keep getting the "no FAT32 partition found".
    1. 2TB Western Digital My Passport drive (FAT32/64K clusters).
    2. WD 1 TB Drive in a generic enclosure (FAT32/64K clusters).
    3. Inateck enclosure (recommended by someone in this thread and got his to work) with 500 GB Samsung drive (FAT32/64K clusters). Here is the link to the enclosure... https://www.amazon.com/gp/product/B00JQTO8TU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

    I DON'T think my board is defective, since I'm able to use with USB stick.
    NOTE: I *DID* have problems at first with the default 2016-12-04 firmware. I would format USB sticks on my PC but then *after* inserting into the USB-GDROM, the USB stick would NO LONGER BE READABLE on the PC. I tried with 5 different sticks, same problem. Insert into USB GD-ROM, USB GD-ROM would read and load games, but when I stuck back into the PC to copy more games, every PC (I tried 4 different PCs) could no longer read USB stick. *** I SOLVED THE UNREADABLE USB STICK ISSUE BY UPGRADING TO 2016-12-08 FIRMWARE**, but have the remaining problem of every hard drive combination that I've tried shows "no FAT32 partition found".

    Do you think that my board is defective and can only read USB sticks (this doesn't make sense, so I'm not sure)? Or, does someone know of an even newer firmware out there? I'm *SORT* of happy with the unit because I can GDI's from USB Stick, but I would rather not buy a larger stick/SDCard when I have 2TB, 1TB, and 500GB drives that I can use.

    *ANY* help will be appreciated. Thanks!

    My best guess is there might be a power issue, if it reads USB sticks and not hard drives. If you can try an external power supply on one of the hard drive enclosures.
