.... and as far as I know, the original ACSI bus was also not
"officially" hot-pluggable.
If that worked for you, Peter, that's fine, but I think you could also
have easily destroyed your hardware that way.

Actually, there is even experimental support for multiple ACSI hard
disk images in the Hatari source code. It's just not configurable in
the GUI yet. But you can add a second ACSI disk in the configuration
file, section "[ACSI]" - but please note that this feature is not very
well tested yet.
