Jim:
If there isn't LBA support or a software translation,
a drive will be limited to 1024 cylinders and will be
limited to 504 MB, regardless of OS.
Older LBA support will end at 4096 cylinders, posing a
2.1 GB limit.
In the modern DOS era and with Windows FAT16, the limit is
2.1 GB. However, NT's FAT16 has a limit of 4 GB (but DOS/Win
cannot see the volume).
Some BIOS support top out at 8100 cylinders which pose
a 4.2 GB limit. A BIOS upgrade may cure this.
With FAT32, the limit is 2 terabytes; however, if you don't
have the latest INT13 extensions, the boot partition will not
be larger then 8 GB. This applies to both IDE and SCSI hard
disk drives. A BIOS upgrade, software translation, or advanced
controller with the latest onboard BIOS support may obviate
this limitation.
NTFS theoretically goes to 16 exabytes.
There are various books, FAQs and white papers on these
drive limitations but I haven't seen one place that has
all the details for all operating systems and hardware, one
that I would recommend. Hope this is fairly complete and
accurate.
