When we format the disk, we usually find the drive letter and right-click to select format, but sometimes this operation does not work. This is where the format command comes in handy. Let's take a look at the format format command series.
FORMAT volume [/FS:file-system] [/V:label] [/Q] [/A:size] [/C] [/X]
FORMAT volume [/V:label] [/Q] [/F:size]
FORMAT volume [/V:label] [/Q] [/T:tracks /N:sectors]
FORMAT volume [/V:label] [/Q]
FORMAT volume [/Q]
Its main parameters are:
volume specifies the drive (followed by a colon), mount point, or volume name.
/FS:filesystem Specifies the file system type (FAT, FAT32, or NTFS).
/V:label Specifies the volume label.
/Q Performs a quick format.
/C NTFS only: By default, files created on this newly created volume will be compressed.
/X Forces the volume to unmount first if necessary. At that point, all open handles to the volume are no longer valid.
/A:size Overrides the default configuration unit size. It is strongly recommended that you use the default settings in general.
NTFS supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K.
FAT supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64k, (128k, 256k for sectors larger than 512 bytes).
FAT32 supports 512, 1024, 2048, 4096, 8192, 16k, 32k, 64k, (128k, 256k for sectors larger than 512 bytes).
Note that FAT and FAT32 file systems have the following limitations on the number of clusters on a volume:
If it is determined that the above requirements cannot be met with the specified cluster size, formatting will stop immediately.
NTFS compression does not support allocation units larger than 4096.
/F:size Specifies the size of the floppy disk to format (1.44)
/T:tracks Specifies the number of tracks per side for the disk.
/N:sectors Specifies the number of sectors per track.
The method of use is as follows:
1. Press win+r, enter cmd, and click OK;
2. Enter format /? after the prompt to view the command parameters and their format;
3. Take the quick format E drive as an example, enter format e:/q and press Enter.
