SYMPTOMS
If Disk Defragmenter is running on one drive and you try to use DriveSpace 3 in protected mode to upgrade another drive from DoubleSpace or Drive- Space to DriveSpace 3 or to uncompress another drive, you may receive the following error messages:

- Windows could not start the DEFRAG.EXE program. Copy the program file to the C:\ directory and then try again.

- There was not enough free space on drive D to complete this task. Some files have not been upgraded to DriveSpace 3 format. These files have been copied to drive H. If you want to upgrade these files you must delete unwanted files from drive D and then try again.

- Not enough free space to upgrade. Between drive H and its host D at least 2.00 MB of physical free space is needed. Try deleting files or moving files to other drives to free up space.

CAUSE
Only one instance of Disk Defragmenter can run at a time. If Disk Defragmenter is running on another drive, DriveSpace 3 cannot start it as part of the process of upgrading or uncompressing the drive.

RESOLUTION
Quit Disk Defragmenter before you use DriveSpace 3 to compress, upgrade, or uncompress a drive.

When you encounter the error messages listed above, two compressed volume files (CVFs) may be left on the drive. These are the original CVF and the new DriveSpace 3 CVF. To complete the upgrade, move the remaining files from the original CVF to the DriveSpace 3 CVF. This procedure may entail reducing the size of the original CVF and increasing the size of the DriveSpace 3 CVF. You may have to do this more than once. Once you move all the files from the original CVF, delete the original CVF using DriveSpace.

MORE INFORMATION
You can upgrade a drive in protected mode if the drive does not contain Windows 95, does not contain the swap file, and is not referenced in the System.ini file.
