I ordered Amigakit's A1200 IDE-to-SD adapter, including their SD-to-MicroSD adapter and MicroSD card.
After a few attempts to install it, it booted and started the Amigakit OS installer. It asked for my Workbench disk, then it started 'assigning directories' but seemingly got stuck at that point (pointer would move and could move the window, but little of use could be accomplished). I left it for at least half an hour then rebooted.
When I switched it back on again, first it acted as if no HDD was connected (even though the HDD light was on, the HDD light has remained on at all times with this adapter) and immediately showed the Kickstart screen. I tried a few power cycles without any difference, then I booted from the Install WB 3.1 disk, and I think it was the HDToolBox program that suggested that no HDDs were connected.
I switched off the Amiga, tried switching MicroSD-to-SD adapters, then booted it at which point it said 'Not a DOS disk in device ADH0'. I switched back to the original MicroSD-to-SD adapter and got the same message. I booted off the Install WB 3.1 disk again and this time the extra partitions showed up (HDD, HDD2) but at the bottom was ADH0: NDOS.
Amiga spec:
C= Amiga 1200
Blizzard 1240+FPU accelerator with 64MB RAM
A500 PSU
No other hardware connected at the time of attempting to use the IDE to SD adapter. I'm fairly sure the Amiga is stable since for example I was able to back up the old HDD via a PCMCIA CF adapter (which took a good hour or two) without issue.
Any help would be much appreciated. I've read up a bit about file system fixing but I wasn't sure whether those kinds of programs would work well with storage hardware such as this.
