The Quantum Daytona 'Go-Drive' range doesn't like the A1200 IDE interface. When I had my Blizzard 1230-IV it would stop it from booting.
For some bizarre reason disabling the CPU cache would allow it to boot but the '030 would get very hot and crash.
I have no idea what the link between the two could be, but a couple of companies reported this problem.
It's also worth considering SCSI drives, you might be able to rig a 3.5" SCSI drive into your desktop case with the floppy-splitter power lead and an accelerator SCSI card.
If you don't want to open the case again you could try those old A600/A1200 PCMCIA hard disks in matching cases. They're pretty rare now though.
