I've discovered that changing the HDToolBox Information to device=buddhascsi.device helps alot in getting the DOM recognized.
May be a no brainer to a lot of people, but I hadn't even thought of it until I got to pondering the typical GVP SCSI device needing that little change.
Still doesn't recognize all the cards, but it's a LOT better now.
Found one off-brand 4GB cf card that works perfectly in a PC, but Amiga thinks it's been write protected, even after I JUST formatted the stupid thing in my PC.
Oh well, I've got a 5GB Seagate microdrive that's working like a champ now.
