Long Filenames Cause Problems with Earlier Versions of MS-DOS

• Microsoft Windows 95

SYMPTOMS

One or more of the following symptoms occur while you are running MS-DOS 6.22 or earlier:

• In a directory listing, the volume label is reported incorrectly.



• When you try to remove a partition, Fdisk reports the following error:

  Volume label does not match




• The Label command reports the following error when changing the volume label:

  Cannot make directory entry




• Symantec Norton Disk Doctor reports files with names such as AA, AB, and AT are too long or too short. Nothing is corrected when Norton Disk Doctor tries to fix the files.
  
  NOTE: The SCANDISK command in Windows 95 reports no errors.

CAUSE

By design, Windows 95 stores long filename information in directory entries adjacent to the file being stored. These directory entries have the Read- Only, Hidden, System, and Volume Label attributes set. Earlier versions of MS-DOS recognize these entries as the volume label. As long as you continue to run Windows 95 and use long filenames, the volume label is unchangeable.

RESOLUTION

If you have removed Windows 95 from your system and want to correct the volume label, use one of the following procedures:

Windows 95 Startup Disk Method

1. Obtain a Windows 95 Startup Disk that contains the LABEL.EXE command line utility for Windows 95.



2. Boot with the Startup Disk and type the following command:

   label <drive>:

   where <drive> is the drive with the unusual volume label.



3. When prompted, enter a new volume label.

MS-DOS 6.x Method

1. Back up your hard disk.



2. Reformat the disk. For example, type the following at the MS-DOS command prompt and then press ENTER

   format <drive>: /s /v:<label name>

   where <drive> is the drive with the unusual volume label and <label name> is the new volume name you want to use.



3. Restore your files.

MORE INFORMATION

Most disk utilities need to be updated to function properly with long filenames.
