After you install DriveSpace or DoubleSpace on a system with Windows for
Workgroups that has an existing network connection on drive H, drive H is
not available under New Swapfile Settings in the Virtual Memory dialog box.
However, existing network connections other than drive H are available.
Under MS-DOS 6.2 or 6.22, drive C is not shown as available for a swap
file. Under MS-DOS 6, drive C is available, but it should not be used
because doing so results in a corrupted swap file warning message.
When DriveSpace or DoubleSpace is set up, it creates a host drive for drive
C. The default host drive letter is H. Having a network connection on drive
H in Windows for Workgroups generates an error indicating it cannot make
the connection. A corrupted swap file error message is also displayed. If
you choose the 386 Enhanced icon in Control Panel, choose Virtual Memory
and then the Change button, neither drive C nor drive H is available as a
To correct this problem, open File Manager and remap the network connection
on drive H to another drive letter. Choose the 386 Enhanced icon in Control
Panel, choose Virtual Memory, and then the Change button. Now both drives C
and H are listed as available drives for a swap file.
