SYMPTOMS

When you start your computer, you may receive the following error message:
Windows has detected a compressed drive access error

CAUSE

This error occurs when Windows 95 cannot mount the compressed drive used during startup because the names of the .bin and the .ini files used for compression do not match.

RESOLUTION

Verify that the versions of the .bin files match the compression version in use. DriveSpace in Windows 95 has file dates of 7/11/95. DriveSpace 3 (included with Microsoft Plus!) has file dates of 7/14/95. If the .bin files do not have the correct date, update the files on the hard disk and the Startup disk (if you have one).

For additional information about updating the Startup disk, please see the following article in the Microsoft Knowledge Base:
136900 Manually Updating the Startup Disk After Installing Microsoft Plus!
If the Drvspace.bin file is present and the Dblspace.bin file is not, and there is a Dblspace.ini file, try the following steps. If one step does not resolve the problem, try the next step.
  1. Create a Dblspace.bin file. To do so, follow these steps:

    1. Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Safe Mode Command Prompt Only from the Startup menu.
    2. At the command prompt, type the following lines. Press ENTER after each line.
      attrib -s -h -r c:\drvspace.bin
      copy a:\drvspace.bin c:\dblspace.bin
      attrib +s +h +r c:\d??space.bin
    3. Restart your computer normally.
  2. Rename the Dblspace.ini file to Drvspace.ini. To do so, follow these steps:

    1. Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Safe Mode Command Prompt Only from the Startup menu.
    2. At the command prompt, type the following lines. Press ENTER after each line:
      attrib -s -h -r c:\ dblspace.ini
      ren dblspace.ini drvspace.ini
      attrib +s +h +r c:\drvspace.ini
    3. Restart your computer normally.
  3. Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Safe Mode Command Prompt Only from the Startup menu. At the command prompt, type the following line
    scandisk /mount=<yyy> <x>:
    where <yyy> is the file name extension of the compressed volume file (CVF), and <x> is the drive containing the CVF. ScanDisk creates a Dblspace.bin file and mounts the CFV. For example, to mount a CVF named D<xx>space.000 on drive C, type the following line:
    scandisk /mount=000 c:
