Try booting off of a Linux live CD / DVD and seeing if it will behave

Not really, unfortunately. The error messages are a bit cryptic:

It seems that the problem lies in the firmware of the ACB4000, which
doesn´t seem to support some standard commands, e.g. the INQUIRY
command. Most recent Linux SCSI drivers seem to use this command.
Some information on this problem can be found here:
https://www.zot.org/~hamish/hacks/acb-4000.html
There´s a thread (in German, sorry) in which someone tried to get a disk
on an ACB4000 to work:
https://de.comp.os.unix.linux.misc.narkive.com/ti21cHO0/scsi-1-platte-unter-linux-ansprechen
and somebody else (also in German...) claims that he could run a disk on
an ACB4000 (from an Atari SH204) on an Adaptec 1542:
https://forum.classic-computing.de/forum/index.php?thread/18576-wie-programme-vom-pc-auf-atari-mega-st-bringen/&pageNo=2
So maybe an Atari ST with an ACSI->SCSI adapter might help. That seems
to be one of the machines we don´t have here...
