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 drive selection.


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.
