Some versions of MS-DOS require you to enter the volume label when formatting a hard drive or deleting an MS-DOS drive using the FDISK command. However, if the volume label is corrupted or was changed by a third-party utility to contain lowercase letters, this is impossible.
To correct this problem, you can use the LABEL command to delete the volume label, then use FORMAT or FDISK. When you are prompted for the volume label, press ENTER (which indicates no volume label).
If LABEL doesn't successfully delete the volume label, you can use the following debug script to erase the first sector of the drive and make it appear unformatted. FORMAT and FDISK can then be used.
To erase the first sector of the drive, do the following.
NOTE: You should not use the following procedure if you are not planning to delete or reformat the drive in question. In general, this is necessary only when the organization of the drive or the information in the drive has been severely damaged.
To start Debug, type debug and press ENTER key.
For MS-DOS versions 5.x and later, you can use the following command to resolve this issue:
Debug Enter Debug Prompt Commands Comments ------- ------------- -------- - F 100 L 200 0 Create a sector of zeros at address 100. - W 100 2 0 1 Write information at address 100 to sector 0 of drive 2* *2 is drive C, 3 is drive D, 4 is drive E, and so on. - Q Quit DEBUG.
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.
format /q /v:VOLUME x:
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.
