DoubleSpace Reports ScanDisk Found Disk Errors (Low Memory) (103531)



The information in this article applies to:
    Microsoft MS-DOS operating system 6.2
    Microsoft MS-DOS operating system 6.22

This article was previously published under Q103531
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

When you try to compress or uncompress a disk with DoubleSpace, you may receive the following error message when the actual problem is low memory:

ScanDisk has detected errors on drive C. Before you can
compress this drive, you must quit DoubleSpace and
then fix the errors by typing SCANDISK /S C: at the
command prompt.

CAUSE

ScanDisk returns exit code 2 (insufficient memory) when it runs out of memory during the system checks. However, when DoubleSpace receives exit code 2 from ScanDisk, it returns the error message noted above. When you run ScanDisk with the command line from the error message, ScanDisk correctly displays one of the following error messages.

If there is not enough space to analyze a Doublespace-compressed drive:

There is not enough free conventional memory to check a DoubleSpace drive.

To run optimally, ScanDisk needs at least 400,814 bytes of conventional memory.
If there is not enough memory to analyze a uncompressed or host drive:

There is not enough free conventional memory to check a drive.

To run optimally, ScanDisk needs at least 367,022 bytes of conventional memory.

RESOLUTION

To work around this problem, increase your available conventional memory. For more information, see Chapter 6, "Making More Memory Available" in the "User's Guide."
