Anyone have any information on these issues (see below)?

SCSI 4.3 was never implemented for machines which had the 53c80 series
of SCSI Controllers. This includes all of the 68000 and 030 machines.
While it probably would have been technically possible there wouldn't
have been much advantage as those machines didn't have DMA or other
hardware which would benefit from the features of 4.3.
I'm not sure why 4.3 would be needed to mount a larger volume. The old
SCSI Manager would work with the proper commands. OTOH newer drivers
that supported the larger volumes may have required the 4.3 APIs for
other reasons. Large volume support was a feature that was added farily
late IIRC and may not have shipped with any releases that were
compatible with the older machines, I don't recall for sure. I thought
large in this case meant larger than 4 GB. Dunno why a disk smaller than
that wouldn't work. Do keep in mind that my memory is distinctly vague
in this area so don't take me at my word.

I'll ask around. It's been a long time and most people here these days
are focussed only on OS X.
Sorry that I couldn't be of more help,

Dear Mr. Bauder,
I seem to recall that you co-wrote SCSI Manager 4.3.x, and I hope that
it's okay to write you and inquire about this.
I've been helping out some (low income senior) folks with their old
68000 & 68030 CISC CPU Macintoshes (SE FDHD {1.4 MB SuperDrive floppy
model}, CLASSIC, CLASSIC II). They all wanted Mac OS 7.1 with Update 3,
as Mac OS 7.5.5 is simply too sluggish on those models.
However, I find that some of the HFS formatted (I checked to make sure
that they are not HFS+ formatted) 1 GB APPLE/ Quantum OEM SCSI hard
disks (removed from other Macintoshes and placed in powered external
SCSI I/II compatible boxes) are being "seen" as being larger than 4 GB,
and they get messages saying that a 68040 or PPC machine and SCSI
Manager 4.3 is needed for mounting volumes larger than 4 GB.
I added the Apple SCSI Manager 4.3.1 extension, but no change.
1) Is there a way to add/implement and activate SCSI Manager 4.3.x on
68000 & 68030 CISC CPU Macintoshes running Mac OS 7.1 with Update 3?
2) Is there anyone you could direct me to, who would have information on
why HFS (not HSF+) formatted 1 GB APPLE/ Quantum OEM SCSI hard disks
would be "seen" as larger than 4 GB under Mac OS 7.1 with Update 3?
It ironic that I can get an external SCSI Iomega 250 MB to be "seen" and
mount fine under Mac OS 7.1 with Update 3 on these models, but not the 1
GB APPLE/ Quantum OEM SCSI hard disks.
APPLE's current site (with many, many broken links) is rather
out-of-date especially in regards to 68K and/or pre-G3/G4 PPC softwares,
hardwares and/or previously posted information (even Mike Kane, John
Couch, Philip Schiller and others couldn't find some of things that used
to be there, and/or provide any more information, when I recently
contacted them on several topics...), so finding things isn't that easy.
Sincerely,
