Ah, I misunderstood. In that case, you are running the OS 3.5
scsi.device.

There isn't a replacement scsi.device with 4 way adaptors, only with
replacement interfaces like the PowerFlyer, and those are loaded
automatically at boot time, before s-s is executed.

The software is patching the standard scsi.device there.

There are two ways of dealing with drives >4GB, TD64 and NSD. Amiga went
the NSD route with 3.5 but PFS3 was already using TD64. So it's possible
for an interface to support drives >4GB and still need the DS version of
PFS3.
you don't have to reformat a drive when switching between the different
versions of PFS3, so it's no real hassle to try the alternative.
