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 are compressing a disk using DriveSpace or DoubleSpace, you receive the following error message:

DriveSpace ran out of free space and some files were left on the newly created drive.



CAUSE
If you run DoubleSpace or DriveSpace on a disk with a partition size between 1028 megabytes (MB) and 1153 MB, you cannot create compressed drives that reach the standard limit of 512 MB.



WORKAROUND
To work around this situation, you must change the partition size to less than 1 gigabyte before you run DoubleSpace or DriveSpace.



STATUS
Microsoft has confirmed this to be a problem in DoubleSpace and DriveSpace. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.



MORE INFORMATION
Compressed volume files (CVFs) that are created on partitions between 1028 MB and 1153 MB cannot be increased. Additionally, the maximum estimated compression ratio (ECR) that can be entered is 1.5 to 1. You can usually make the CVF smaller and decrease the ECR.

If all the data cannot be compressed, it remains available on the host drive.

Following are examples of the maximum size of the CVF for a number of partition sizes between 1028 MB and 1153 MB:   Partition   CVF ---   1028      11    1034      16    1030      33    1040      50    1050      88    1070     145    1080     168    1090     184    1144     341 NOTE: All values are in megabytes.
