Sorry If I didn't make myself clear, I am suggesting one never

The Finch was a short lived 8-inch HDD that went up to 42 MB
unformatted BUT according to Disk/Trend It did not use an ST506
interface but instead came with this variety of interfaces: Finch,
LDI, SMD or SA1000! So your problem is likely to be finding a drive
that matches the interface of yr controller card. Some possibilities
· Finch interface was available on certain CDC Wren 5½-inch
models, e.g. 9415
From what I understood in the Zilog System 8000 manuals, it is the
Finch interface.
