ECR Cannot Be Decreased Beyond a Certain Range (97671)
The information in this article applies to:
- Microsoft MS-DOS operating system 6.0
- Microsoft MS-DOS operating system 6.2
- Microsoft MS-DOS operating system 6.22
This article was previously published under Q97671 SYMPTOMS
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.
The estimated compression ratio (ECR) cannot be decreased beyond a
certain range if a drive has become too fragmented.
CAUSE
This situation occurs when there is a large unused section in the file
allocation table (FAT) and a used cluster exists at the very end. If
you could reduce the ECR below the value DoubleSpace limits you to,
the last cluster would be truncated by the edge of the new FAT table
size.
WORKAROUND
To work around this problem, run Microsoft Defragmenter (Defrag) on
your compressed drive.
