Cannot Uncompress Some Floppy Disks Without Removing Data (104544)
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 Q104544
This information applies to both Microsoft DoubleSpace and Microsoft
DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands
If you compress a floppy disk and immediately try to uncompress the
disk, you may receive the following error message:
DoubleSpace cannot uncompress drive <letter> because
there is not enough space on drive <host letter> to hold all
of the uncompressed files.
To uncompress drive <letter>, you must remove at least
<xxx,xxx> bytes of files from either drive.
This occurs because DoubleSpace is very conservative in estimating the
space required to hold the uncompressed files. The estimate is based
in part on a worst-case scenario in which the data on the floppy disk
is stored at a 16:1 compression ratio and DoubleSpace must convert the
drive from a 16-bit file allocation table (FAT) to a 12-bit FAT.
To work around this problem, remove <xxx,xxx> bytes of data from
either the compressed drive or the host drive.
