SYMPTOMS
When you start Microsoft Windows or Windows for Workgroups, you receive one of the following error messages:

The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be loaded. There is unrecognizable disk software installed on this computer.

"-or-"

The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be loaded. There is a conflict with another virtual device.

"-or-"

This application has tried to access the hard disk in a way that is incompatible with the Windows 32-bit disk access feature (WDCTRL). This may cause the system to become unstable.

"-or-"

The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be loaded. There is unrecognizable disk software installed on this computer. The address that MS-DOS uses to communicate with the hard disk has been changed. Some software, such as disk-caching software, changes this address. If you aren't running such software, you should run a virus-detection program to make sure the computer is virus free. To continue starting Windows without using the 32-bit disk driver, press any key.

CAUSE
The above error messages can be displayed when:


 * The system is infected with a virus.

-or-
 * You are running the PC Cillin anti-virus program.

-or-
 * The Device=*WDCTRL entry occurs more than once in [386Enh] section of the SYSTEM.INI file.

-or-
 * You are using a third-party replacement for WDCTRL and you have reinstalled Windows.

-or-
 * You are loading a real-mode driver in the CONFIG.SYS file that alters the manner in which Windows monitors and controls INT 13h.

-or-
 * Using a QD6500A VLB controller that was installed in Windows 3.1 and then installing WFW 3.11. After the install there will be an *int13, WDCTRL, and QDICTRL.386 in [386Enh] section of system.ini. QDICTRL.386 alone breaks the IFSHLP.SYS. Remark out the QDICTRL.386 line and use the WDCTRL. Leave the QD6500.SYS line in the config.sys.

The System Is Infected with a Virus
During startup, if Windows detects that a particular undocumented interrupt has been hooked by a &quot;program&quot; it does not recognize, Windows displays one of the above messages. Quite often, the program it does not recognize is a virus. The Stoned, Bloomington, and Form viruses can cause these errors.

To correct this problem, run virus-detection software to detect and remove any viruses from the hard disk drive. The Anit-CMOSa virus will also cause this; McAfee v2.14 will find, but not cure it.

You Are Running the PC Cillin Anti-Virus Program
PC Cillin anti-virus software can cause these error messages. For more information on PC Cillin and problems with Windows, query on the following words in the Microsoft Knowledge Base:

You Are Using a Third-Party Replacement for WDCTRL and You Have Reinstalled Windows
If you have a Western Digital Caviar 2540 hard disk drive (or another model that uses WDCDRV.386 as a replacement for WDCTRL) and you reinstall Windows to the same directory, Windows puts WDCTRL in the SYSTEM.INI file but does not remove the third-party driver. Removing the DEVICE=*WDCTRL entry from the SYSTEM.INI file corrects this problem.

You are Loading a Real-Mode Driver in the CONFIG.SYS File That Alters the Manner in Which Windows Monitors and Controls INT 13h
Real-mode drivers that manipulate the way in which INT13 calls are handled may prevent the 32-bit disk access driver from loading.

The issue can also occur if the CD-ROM drivers for a new 50-speed CD-ROM drive conflict with 32-bit disk access. Disabling 32-bit disk access in the Virtual Memory settings in the 386 Enhanced tool in ControlPanel may allow the CD-ROM to be accessed in Windows with no error messages.
