DriveSpace Does Not Compress Existing Drive (128767)


The information in this article applies to:

  • Microsoft Windows 95
This article was previously published under Q128767

SYMPTOMS

When you are using DriveSpace to compress an existing drive, the mini- Windows portion of DriveSpace does not load.

CAUSE

This problem can occur if you are using a Diamond SpeedStar Pro VLB video adapter, and the following line has been removed from the AUTOEXEC.BAT file: 
   C:\UTIL1\SPEED\PROMODE MONITOR
This line is needed in order for the video adapter to support VGA mode in mini-Windows.

RESOLUTION

To correct the problem, follow these steps:
  1. Add PROMODE.EXE to the [FAILSAFE] section of the DRVSPACE.INF file.
  2. Copy the PROMODE.EXE file to the fail-safe directory on the host drive.
  3. Add a line in the AUTOEXEC.BAT file to load PROMODE.EXE and then restart the computer.

MORE INFORMATION

Some older Diamond video adapters need the PROMODE.EXE driver for VGA support. When you try to compress an existing drive, the computer restarts and cannot load mini-Windows and no compression takes place. There is no support for computers that load required drivers from the AUTOEXEC.BAT file.
