ID: Q147132

The information in this article applies to:
  • Microsoft Windows 95

SUMMARY

This article describes how to prevent the DoubleSpace or DriveSpace driver from being loaded into memory.


MORE INFORMATION

The DoubleSpace or DriveSpace driver is loaded under either of the following conditions:

  • There is a Dblspace.ini or Drvspace.ini file present on the host drive on the boot disk. This is usually drive H, but it can be drive C if the boot disk is not compressed.


  • There are lines in the Msdos.sys file calling the driver.


Temporarily Disabling the Driver

To temporarily bypass the loading of the Dblspace.bin or Drvspace.bin driver, restart your computer, and then press CTRL+F5 when you see the "Starting Windows 95" message.

Permanently Disabling the Driver

To permanently disable the Dblspace.bin or Drvspace.bin driver, follow these steps:
  1. Make sure Windows 95 is configured so you can view hidden and system files. For additional information, please see the following article in the Microsoft Knowledge Base:
    Q141276 How to View System and Hidden Files in Windows 95


  2. Click the Start button, point to Find, and then click Files Or Folders.


  3. In the Named box, type dblspace.ini. Click the Include Subfolders check box to clear it, and then click Find Now.


  4. If a Dblspace.ini file is found, use the right mouse button to click the file, click Rename on the menu that appears, and then rename the file to Dblspace.sav.


  5. In the Named box, type drvspace.ini, and then click Find Now.


  6. If a Drvspace.ini file is found, use the right mouse button to click the file, click Rename on the menu that appears, and then rename the file to Drvspace.sav.


If the DoubleSpace or DriveSpace driver is still loaded when you restart the computer, follow these steps:
  1. Start an MS-DOS session.


  2. At the command prompt, type the following lines. Press ENTER after each line:
    cd\
    attrib -s -h -r msdos.sys
    edit msdos.sys


  3. In the [Options] section of the file, search for the following lines:
    Dblspace=0
    Drvspace=0
    If these lines do not exist, add them to the [Options] section.


  4. Save the Msdos.sys file and then quit the editor.


  5. Type attrib +s +h +r msdos.sys, and then press ENTER.


  6. Restart the computer. The DoubleSpace or DriveSpace driver should not be loaded.
