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
If you run Microsoft Defragmenter (Defrag) and your DoubleSpace compressed volume file (CVF) is full or nearly full, Defrag reports the following:

Error writing cluster nnn,nnn

Use a disk repair program to fix, and then run DEFRAG again.



CAUSE
If CHKDSK shows no problems and a surface scan utility, such as Symantec's Norton Utilities Norton Disk Doctor (NDD.EXE), shows no problems, the error message is occurring because Defrag is unable to write the information that it has read. Defrag is trying to copy a cluster before moving it, but since the DoubleSpace-compressed drive is too fragmented or full, there is no space large enough to write the cluster.



WORKAROUND
To work around this problem:
 * Increase the size of your DoubleSpace-compressed drive and then run Defrag. -or-


 * Delete enough files to allow Defrag to run.

Additional query words: 6.00 6.20 dblspace double space
