SYMPTOMS
========

When you use the Windows 95 DriveSpace compression utility to delete a
compressed drive, the following error message is displayed:

  Windows cannot perform this operation because the enhanced mode disk
  compression driver could not be loaded. You may need to run setup again to
  install additional disk components. DRVSPACE 545

CAUSE
=====

This problem occurs if the Windows 95 protected-mode DriveSpace driver
(DRVSPACX.VXD) is missing or corrupted. In such cases, Windows 95 loads the
real-mode DriveSpace driver. Deletion operations are not possible with the
real-mode driver.

RESOLUTION
==========

To correct this problem, extract the file DRVSPACX.VXD from the original Windows
95 disks or CD-ROM. To extract the file, perform the following steps:

1. Rename the DRVSPACX.VXD file on your hard disk. This file should be located
  in the WINDOWS\SYSTEM\IOSUBSYS subdirectory.

  a. To rename this file, first click the Start button on the taskbar. On the
     Find menu, click Files Or Folders.

  b. In the Find: All Files dialog box, type "drvspacx.vxd" (without the
     quotation marks) in the Named box. Click the Find Now button.

     NOTE: If DRVSPACX.VXD is missing, that is, it is not found on the hard disk
     that contains Windows 95, skip to step 2 below.

  c. In the file listing box, use the right (secondary) mouse button to click
     the file DRVSPACX.VXD and then click Rename. Rename the file DRVSPACX.OLD
     and then press ENTER.

     NOTE: It is important that you use an extension other than .VXD when
     renaming files.

2. Extract a new DRVSPACX.VXD from the Windows 95 disks to the
  WINDOWS\SYSTEM\IOSUBSYS subdirectory. To extract the file, insert Disk 11 in
  the floppy disk drive, or insert the Windows 95 Setup CD in the CD-ROM drive,
  then follow the steps below.

  a. On the taskbar, click Start. On Programs menu, click MS-DOS Prompt.

  b. At the command line, type the following

  " extract /l <drive letter>:\windows\system\iosubsys <drive
  letter>:\A drvspacx.vxd " (without the quotation marks)

     where <drive letter> indicates the letter designating the drive
     containing the floppy disk or CD-ROM.

3. Restart the system.

  NOTE: For additional information about the EXTRACT command, type "extract /?"
  (without the quotation marks) at the MS-DOS prompt.

MORE INFORMATION
================

If DRVSPACX.VXD becomes corrupted or is accidentally deleted from the system,
the real-mode driver loads by default. DriveSpace cannot perform any operation
using the real-mode driver while running under Windows 95. However, some
operations (such as unmount and change letter) can be performed by making
changes to the DRVSPACE.INI file and then restarting the system. However, the
FORMAT and DELETE commands cannot be performed without the full support of the
file system. These commands cannot be run with the real-mode driver.
