Actually, there is no technical reason why this would not work out of
the box. With SATA drives connected to the Falcon it works, with the
same drive it works with Hatari and the SCSI Driver (see attachment),
and this is actually not different from a regular ACSI or SCSI setup.
Of course, in practice these setups are unlikely. But this is just about
what's technically possible.

With an ICD compatible adapter you can use any SCSI command with ACSI,
it only requires some more SCSI commands to be emulated.
What I was just wondering is why there seem to be problems with sector
numbers below the 32 bit limit.

Yes, I remember the fseeko issue. Maybe I will have a closer look at this.
Just wanted to know whether there are any known issues.

Take care
