Bingo!
I had set the image to read only. Allowing writes to it let the desktop
import several of the partitions. So read-only images are not allowed.
Bug? Or if that's a feature, please document it.
Could you test attached patch that changes this?
So here's what I see: I have two other disk images, one partition each.
They show up as C: and D:. Then four partitions from the new image, E:
through H:. I: is my GEMDOS mounted directory. J: to O: are further
partitions from the new image. Is that the drive ordering you want, or
should the GEMDOS drive show up as O:? I was expecting it at O:.
Hatari default for GEMDOS HD partition ID is "skip", i.e. place it
after partitions that Hatari HD code recognizes.
In any of the cases where on-disk HD driver and Hatari interpretation
of the partition tables mismatches, GEMDOS HD won't be the last one.
This mismatch can happen easily because Hatari doesn't know which
HD driver is on the HD image or what partition types that recognizes
/ supports (partition support *does* differ between different drivers).
As a result, GEMDOS HD can mask one of the real HD partitions (or more,
if there are multiple GEMDOS HD partitions specified).
That's why there's an option to explicitly set the GEMDOS HD partition
ID:
--gemdos-drive X
