It really was amazing how quickly hard drive sizes overran system
vendors' expectations. You'd think that system software authors would
anticipate very large drives right from the start. But stumbling along
with 16MB, then 32MB drive size limits just illustrates how
backward-thinking folks were. CP/M 2.2 had, what, an 8MB hard drive
limit initially? That was backward even for 1980.
And then you get a surprise every once in awhile. I was incredulous
that one of my "devices" had a limit of 2GB on a CF drive, but the thing
actually understood a DOS partition table. So you could take a 4GB or
more drive, partition off the first 2GB and you're still gold. Can't
swap partitions--the thing just takes the first one in the table, but
still pretty surprising.
