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.



SYMPTOMS
DoubleSpace may be unable to use all the space available on your drive if you are using Symantec Norton Utilities Erase Protect (EP.EXE) or Norton Desktop for Windows (NDW) SmartErase. If so, DoubleSpace exits and displays the following message:

Dlspace is finished compressing this drive. Some files were not compressed you will have to back up these files, resize the dblspace drive, then restore the backup.



WORKAROUND
To work around this problem, empty your Erase Protect TRASHCAN directory and disable Erase Protect before you install DoubleSpace.



MORE INFORMATION
If you have already installed DoubleSpace, do the following:

 Empty your TRASHCAN directory. Increase the size of your DoubleSpace drive. To do this, type the following at the MS-DOS command prompt and then press ENTER

dblspace /size /reserve=2

where is the drive letter of your compressed drive. Move the remaining files from your uncompressed host drive to your compressed drive. After you move all the files from your uncompressed host drive, increase the size of your DoubleSpace drive by choosing Size from the Drive menu in Setup.

How Erase Protect Works
If you have Erase Protect or NDW SmartErase loaded, when you delete files from your hard disk, they are moved into a hidden directory (TRASHCAN) instead of being deleted.

When you type DIR or run Windows File Manager to determine the free disk space, Erase Protect and SmartErase intervene and cause MS-DOS to report the disk space available as if the TRASHCAN directory were empty.

To determine the actual free disk space, run CHKDSK.
