SUMMARY
In MS-DOS versions 1.x and 2.x, the FORMAT command formats the currentdrive unless another drive is specified. For example, the command
   C:\dos>format				
formats drive C.

MS-DOS versions 3.0 and later require that you specify the drive to beformatted (for example, FORMAT C:); if no drive is specified, FORMATdisplays the error:
Required parameter missing
MORE INFORMATION
Also in versions 3.0 and later, FORMAT displays the message
WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST!
Proceed with Format (Y/N)?
when you issue the FORMAT command for a hard drive. To format thedrive, press Y, then press ENTER.

In MS-DOS versions 4.x, FORMAT requires that you enter the drivevolume label before it will format a hard disk. This protectionfeature was removed from MS-DOS versions 5.0 and 5.0a.
