Specific notes concerning file systems and compatibility
1. FAT or FAT16 is compatible with every Microsoft Operating System and version of
Windows (MS-DOS up to v6.22, Windows 3.x, Windows 9x, Windows ME,
Windows NT, and Windows 2000).
2. FAT32 is only compatible with Windows 95 OSR2, Windows 98, Windows ME, and
Windows 2000.
3. NTFS is only compatible with Windows NT and Windows 2000.
These compatibility issues do not affect sharing over a network.
Examples of compatibility:
If a Windows 98 machine has it’s (FAT32 formatted) hard drive shared out on the network,
a Windows 3.x, Windows NT, and Windows 2000 machine will still be able to see and
read the share properly over the network.
If a RAID Tower has been formatted with an NTFS partition and is directly connected to a
Windows 98 machine, the Windows 98 machine will not recognize the NTFS partition on
the RAID Tower.
