Specs: Windows XP
Hello all. My wife's laptop's hard drive seems to revert to PIO mode from UDMA 5 whenever I try to run a virus scan or check the disk for errors. I can uninstall and let XP fix it upon rebooting, but this is becoming a nusiance that I'd like to fix. It's a Toshiba laptop and the BIOS doesn't have any editable parts for the IDE channels. Toshiba doesn't have any drivers I could try from their website. Any ideas?

In device manager, choose IDE controller(master and slave) and then advanced setting change the mode to DMA

Hi, thanks for the response. I'd already tried changing the setting in Device Manager and also uninstalling the channel from Device Manager. It was a temporary solution. It still dropped speed levels when I would try a virus scan or check the disk for errors. UPDATE: I noticed that the particular file that seemed to caused the error when accessed was the same file that caught the eye of Hitman Pro virus scanner last week. The file is a part of the Intel Graphics Driver. So I used the laptop's recovery and application cd and reinstalled the original graphics driver. Virus scanned complete! and without any PIO mode! I also reinstalled the motherboard drivers while I was at it. I was still unable to check the disk for errors. That did still cause a problem with PIO mode. So I'll take a near-victory right now for this because it's been a freaking headache.
