-
- Windows NT supports most removable hard disks and magnetic-optical
- disk drives. These disks are treated as hard disks because they must
- be partitioned and they are assigned a drive letter. However, Windows
- NT does not support write-once disk drives.
-
- Windows NT supports removable media subject to the following
- restrictions:
-
- - A removable hard disk can have only one primary partition. Extended
- or logical partitions are not supported.
-
- - Windows NT supports only the Windows NT filesystem (NTFS) and
- MS-DOS-compatible (FAT) file system on removable media.
-
- - The user cannot assign the drive letter for the device.
-
- - Removable disks are not supported in a fault tolerant manner.
-
- - You can install the Windows NT system files (the files contained in the
- WINNT directory) on a removable disk. However, the boot partition and
- associated files must be on a hard disk drive (fixed disk).
-
- - If the paging file is located on the device or if the device has
- the NTFS installed, the media is locked until the system is
- shutdown.
-
- - The FAT file system locks the media while it is in use and unlocks
- it after approximately 10 seconds of inactivity.
-
- NOTE: Windows NT supports a 20.8MB "floptical" disk as a floppy
- disk, not as a hard disk. Each write to a floppy disk is
- performed on a write-through cache basis and you can remove a
- floppy disk as long as the drive light is not on.
