This article provides a list of the floppy disk formats that are supported in Windows XP.
Windows XP supports the following floppy disk formats:
1.44 megabyte (MB) 3.5" floppy disk (read, write, format)
720 kilobyte (KB) 3.5" floppy disk (read, write only)
1.2MB 5.25" floppy disk (read, write, format)
360KB 5.25" floppy disk (read, write, format)
Note You can format these disks only by using a command at a command prompt.
Windows XP supports formatting only the 1.44MB disk format. Three-mode floppy drives (drives that are capable of reading/writing with 720KB, 1.2MB and 1.44MB 3.5" disks) requires special driver support, and support for this feature is not included in Windows XP.
Some 3mode FD drivers may be installed on PCs with Windows XP by OEMs, although Microsoft does not provide the end-user support for 3mode drivers. Please contact your OEM (Original Equipment Manufacturer) if you have any questions on 3mode drivers.
