Desavalo mi se to ranije (davno) i problem je bio u registry-ju. a evo sta microsoft kaze oko toga:
To cause Windows to attempt to reinitialize the protected-mode IDE driver:
Click Start, click Run, type regedit in the Open box, and then press ENTER.
Locate and click the following registry key:
In the right pane, right-click the NOIDE value, and then click Delete.
Quit Registry Editor.
After you update the registry, restart Windows. Windows attempts to initialize the protected-mode driver for the controller. If Windows can initialize the protected-mode driver for the controller, the file system and virtual memory operate in 32-bit mode and Device Manager does not display an exclamation point in a yellow circle for the IDE channels.
If the protected-mode driver is not initialized properly, you receive an error message and the NOIDE value is re-created. Windows uses the MS-DOS Compatibility mode file system the next time that you start the computer. If you are running Windows 98 on your computer, locate the Tools\Mtsutil folder on the Windows 98 CD- ROM, right-click the Noide.inf file, and then click Install. When you do this, the NOIDE value is deleted if it exists. After you use this file, restart your computer.
Obicno to resava stvar :)
