I don't think so. Through System 7.5, the Mac did support up to 2 GB per 
partition and up to 8 partitions per drive, so any Mac should be able to 
handle up to a 16 GB hard drive.

With 7.5.5 or 7.6, Apple doubled that to 4 GB partitions, and with 8.0 or 
8.1 moved somewhere into the terabyte range (4?).

For the record, DOS supported drives to 32 MB, then had to be rewritten 
to pass that limit. A few years later they had to rewrite the MS 
operating systems again to support 512 MB drives. And Win95 won't work 
with drives (or is it just partitions?) over 2 GB.

Amazing to think System 6 and 7 would work with 2 GB partitions back when 
DOS had a 32 MB barrier. ;-)

As for terabyte drives on a Power Mac 9500, that's going to depend on 
which version of the Mac OS you're running.

I was to learn later in life that we tend to meet any new situation by 
reorganizing, and what a wonderful method it can be  for creating the 
illusion of progress while producing confusion, inefficiency, and 
demoralization. - Petronius
