NOTE: Windows 95 OEM Service Release version 2 and later support drives larger than 2 GB using the FAT32 file system. For more information about the FAT32 file system, please see the following article in the Microsoft Knowledge Base:
TITLE : Description of the FAT32 File System
Note that the hard disk drive must be supported by the computer's ROM BIOS APIs, which have a 1024-cylinder limitation, in order for FDISK to partition the hard disk.
Because 32K per cluster can waste valuable hard disk space, the FAT file system is not always the best hard disk management scheme. Microsoft Windows NT uses the NT File System (NTFS), which uses a different file/cluster scheme. Microsoft OS/2 version 1.3 offered HPFS, which also uses a more conservative method of allocating disk resources.
NOTE: Microsoft Windows NT also supports FAT drives. Windows NT 3.51 supports FAT drives up to 4 GB in size. FAT drives from 2 GB to 4 GB in size are not supported by MS-DOS or Windows. In other words, if you wish to have a FAT drive accessible from MS-DOS or Windows 95/98 and Windows NT, your FAT drive should be no larger than 2 GB. If you will be accessing the FAT drive from only Windows NT, then the drive can be 2 GB to 4 GB in size.
