| The maximum capacity that can be described by the partition table is:
(sector size) X (sectors per track) X (cylinders) x (heads)
or
512 X 63 X 1024 X 256 = 8,455,716,864 bytes or 7.8 GB
In Windows NT, the maximum cluster size for FAT is 64K when using a
512 byte sector, so the maximum size for a FAT volume is 4 GB. If NT
is in a dual-boot configuration with WIN95 or MS_DOS, FAT volumes are
limited to 2 GB with the other operating systems.
When using NTFS, the architecture allows for 2^^64, or 16 exabytes,
which is beyonde the capability of most hardware today. Current
physical limits on hardware reduce this to 2 terabytes (2^^32 * 512
bytes, or 2^^41 bytes).
For further detailes, consult Chapter 3 (Disk Management Basics) of
the WINDOWS NT SERVER Resource Guide.
