In your device manager (under hard drives), unless you are using another controller software enhancing package like Intel Application Accelerator.

what os?

if win2k. right click 'my computer' go to properties, then click the hardware tab. Then click 'device manager'. Go down to 'IDE controllers' Expand it. Go to the primary controller and right click it and go to properties. Click the advanced settings. It will tell you there.

If you're in PIO mode, go to microsoft.com and install service pack 2. Reboot and you should be good. Otherwise start looking for a new driver for the drive.

Hope it works.

Your problem is system related. If you have a Via chipset, update to the latest drivers. If that doesn't solve it, search this forum for "ACPI" there are many posts that will be of help.
