If you click Details, you see the following information:

CAUSE

The Windows 95 protected-mode Standard IDE/ESDI Hard Disk Controller driver is not compatible with Green Caching VLB IDE controllers and other related controllers.

RESOLUTION

To work around this behavior, disable the Standard IDE/ESDI Hard Disk Controller in Device Manager and enable the vendor-provided FastDisk driver. To do so, follow these steps:

Use any editor (such as Notepad) to edit the System.ini file. Add the following line to the [386Enh] section of the file
```
      device=<path>\<FastDisk driver>
```
where <path> is the path to the vendor-provided FastDisk driver, and <FastDisk driver> is the name of the FastDisk driver file. For example, if the FastDisk driver file is named Wdctrl32.386, and it is located in the C:\Drivers folder, enter the following line:
```
      device=c:\drivers\wdctrl32.386.
```
Save and then close the file.
In Control Panel, double-click the System icon.
On the Device Manager tab, double-click Hard Disk Controllers.
Click the Standard IDE/ESDI Hard Disk Controller device, and then click Properties.
Click the Original Configuration (Current) check box to clear it, and then click OK. Click OK until you return to Control Panel.
When you are prompted to restart your computer, do so.
