Format a disk for use with Windows.
Syntax FORMAT drive: [/FS:file-system] [/V:label] [/Q] [size] [/C]
Key /FS:file-system The file system (FAT or NTFS).
The NTFS file system does not function on floppy disks.
/V:label The volume label.
/Q Quick format.
/C Compression - files added to the new disk will be compressed.
[size] may be defined either with /F:size or /A:size
/F:size size is the size of the floppy disk (720, 1.2, 1.44, 2.88, or 20.8).
/A:size Allocation unit size.
Default settings (via /F) are strongly recommended for general use.
NTFS supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K. FAT supports 8192, 16K, 32K, 64K, 128K, 256K. NTFS compression is not supported for allocation units above 4096.
Echo Warning this will reformat the entire D: disk!
format D: /FS:NTFS /x
