If you adapter is really for MMC rather than SD (from the megabytes not gigabytes era) then it might not support SD at all, or not SDHC, or some arbitrary size limit. Only thing is to try it.

I suspect it is an IDE to Compact Flash adapter incorrectly described as
MMC.

Quite right!

Ah, that changes things! In that case I'd be looking at an IDE to SATA adapter plus a SATA SSD.
The A9home's IDE implementation was designed by Simtec, and I think the Simtec IDE ports (Unipod etc) were designed to a more modern spec and had better luck with adapters than the Acorn motherboard ones on Risc PCs.

I'll check them out on Amazon. If anyone is already using on with the A9home, please drop me a link to it.

Over the years I have the IDE interace on the A9home to be be quite picky over what it will work with. Even down to which interface it will work
on! For example my current CF adaptor will not work on the interface underneath, but works fine via a cable on the top interface!
