This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames.

When you run Symantec Norton Utilities Speed Disk (SPEEDISK.EXE) and choose to optimize a previously unmounted DoubleSpace-compressed floppy disk, Speed Disk does not display the floppy disk as a DoubleSpace-compressed disk.

The DoubleSpace-compressed floppy disk is automatically mounted, but Speed Disk does not update its display correctly. Also, the DoubleSpace-compressed floppy disk's host drive is not displayed.


To make Speed Disk correctly display the DoubleSpace-compressed floppy disk and its host drive:

  • Access the floppy disk before you run Speed Disk. For example, type dir a: at the MS-DOS command prompt and then press ENTER before you run Speed Disk. -or-

  • Exit Speed Disk and then restart it.
