In MS-DOS versions 1.x and 2.x, the FORMAT command formats the current drive unless another drive is specified. For example, the command
formats drive C.
MS-DOS versions 3.0 and later require that you specify the drive to be formatted (for example, FORMAT C:); if no drive is specified, FORMAT displays the error:
Required parameter missing
Also in versions 3.0 and later, FORMAT displays the message
when you issue the FORMAT command for a hard drive. To format the drive, press Y, then press ENTER.
WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST!
Proceed with Format (Y/N)?
In MS-DOS versions 4.x, FORMAT requires that you enter the drive volume label before it will format a hard disk. This protection feature was removed from MS-DOS versions 5.0 and 5.0a.
