For MS-DOS versions 5.x and later, you can use the following command to
resolve this issue:
format /q /v:VOLUME x:
where "VOLUME" is the new volume name you want to assign to the hard disk
drive, and "x:" is the drive letter you want to format.
MS-DOS versions 3.x FORMAT commands require you to enter the volume
label to format a hard disk.
In all MS-DOS versions, FDISK requires you to enter a volume label;
however, in MS-DOS 5.0 and later it checks for unprintable characters in
the volume label. If unprintable characters exist, FDISK treats the volume
label as if does not exist.
