Dragging up this old thread. I finally got one of these adapters to test in the GVP sidecar on my A500, since the case can't close anymore with the Guru-ROM sitting in its PCB adapter sitting underneath the Mechware card reader.
Adapter arrived quickly from AmigaKit already flashed with what appears to be the latest firmware (4.7.1), kudos for that.

Prepped an old 4GB MicroSD on my A2000 (via card reader), popped it in the adapter, and popped the adapter into the sidecar. On preliminary tests it seems to be "okay", in that the Amiga sees the card reader and can read the data off it that I put on there with my A2000, I was able to load SysInfo from command line (off the MicroSD when booting with no startup-sequence), but am getting a lot of errors related to HD_SCSI mode. I'm thinking this is something I need to enable on the device but none of the options are quite clear (screenshots attached). Any suggestions?
Edit - file system is PFS3-AIO if that makes a difference.
Edit 2 - removed one of the screenshots that wasn't actually an issue with the SCSI2SD.
Edit 3 - looks like I need to check the box to enable SCSI 2,
per this thread. Might've just solved this myself, LOL.
