Q. Why does DoubleSpace create a drive identified by the letter H when I have drives A, B, and C only? A. To avoid conflicts with existing drives, DoubleSpace examines the existing drive assignments during installation to find the highest drive letter currently in use. It then skips the next four letters and assigns the fifth letter to the new DoubleSpace drive. For example, if your computer has two floppy disk drives (A and B) and a hard disk drive (C), DoubleSpace locates the highest letter (C); skips drive letters D, E, F, and G; and then assigns drive letter H for its own use. For more information, refer to the "Freeing Disk Space" chapter in the "Microsoft MS-DOS 6 User's Guide." 2. Q. I am currently using a third-party disk-compression software package and now want to convert to DoubleSpace. How can I do this? A. If you are using a third-party disk-compression software package, you need to back up your program and data files, install MS-DOS 6.0, remove your third-party disk-compression software, compress your drives with DoubleSpace, and then restore your program and data files. For more detailed information, order FastTips Technical Library item Q103949, titled "Converting to DoubleSpace from Third- Party Disk Compression." 3. Q. I installed DoubleSpace and now each time I enter Microsoft Windows(TM) I receive the error "Corrupt Swapfile Warning." I have set up my permanent swap file many times, but I continue to receive this error. How can I correct this problem? A. In this case, the error "Corrupt Swapfile Warning" probably means your permanent swap file is being created on a DoubleSpace-compressed volume. Windows cannot create a permanent swap file on a compressed volume. To correct this problem, set the permanent swap file to a noncompressed drive. Windows cannot detect DoubleSpace-compressed drives because Windows' release predates the release of DoubleSpace. For more information, refer to the "Freeing Disk Space" chapter in the" Microsoft MS-DOS 6 User's Guide," or type "HELP DBLSPACE" (without the quotation marks) at the MS-DOS command prompt and press ENTER. 4. Q. I am running the Defragmenter (DEFRAG) to reorganize the files on my disk drive, but it appears that the program has stopped. How should I proceed? A. If you are running the Defragmenter on a DoubleSpace-compressed drive, the system may appear to stop when the Defragmenter calls DoubleSpace to defragment the compressed volume file (CVF). If this occurs, do not turn off your computer or press the reset button. If you want to quit DEFRAG or DBLSPACE /DEFRAG, press the ESC key to interrupt the program. If you think DEFRAG or DBLSPACE /DEFRAG has stopped responding, press the ESC key. If this does not work, you must restart your computer. To do so, it is preferable to press the CTRL+ALT+DEL key combination; however, if that does not work, press the reset button or turn off your computer. 5. Q. Because DoubleSpace has assigned drive F for its own use, my Novell(R) NetWare(R) logon scripts no longer work. How can I correct this problem? A. The drive letter F (normally used by Novell NetWare) may be used by DoubleSpace. To work around this situation, you can either use a different drive letter for your login drive, or you can adjust DoubleSpace so that it uses a different drive letter for its host drive. If your usual NetWare drive letter is unavailable, use one of the following methods to change the DoubleSpace host drive letter: - Ensure any C:\DOS\DBLSPACE.SYS commands are placed before any RAMDRIVE.SYS statements in your CONFIG.SYS file. -or- - Edit the DBLSPACE.INI file and change the host drive letter. For specific instructions, order FastTips Technical Library item Q97565, titled "Novell Login Drive Not Available After Installing DoubleSpace." NOTE: You can usually avoid this problem by making sure your NetWare software is loaded before you run DoubleSpace to compress your drives.
