Ok here's the deal... WD 80GB "Special Edition"(8MB cache) drive as my master(system and apps) WD 120GB "Special Edition" as slave(pagefile, multimedia storage(pornnaughty: )). Both drives are on IDE channel 1 of an onboard ATA 100 controller(Gigabyte GA-7VRXP Mboard) AMD Athlon XP 2000 Win XP Note above that I keep the pagefile on the non-system drive. A couple days ago I started noticing lagging performance and weird HD accessing. I checked the Windows event viewer and was getting errors like these: Atapi error, event ID 9, "The device, \Device\Ide\IdePort0, did not respond within the timeout period." Disk warning, event ID 51, "An error was detected on device \Device\Harddisk1\D during a paging operation." And these events were occurring during the weird HD accessing I was noticing. So clearly something was wrong with the 120GB drive that had the pagefile on it. I decided to run benchmarking tests on the drive and found out the drive transfer speeds were TERRIBLE! It was like 3MB/s!!! The system drive speeds were more like 30MB/s, which is normal. I checked the windows device manager, and under the IDE controllers section, I selected the primary IDE channel and found out that both drives were set to UDMA speeds, but the second drive is operating at PIO speed! Normally both drives run at UDMA 5, and the system drive still is. I have tried everything I can think of but there aren't a lot of settings for this kind of thing. All I know is everything is set correctly in the BIOS, and until a couple days ago both drives were at UDMA 5 speed and working just fine, then all the sudden the second drive starts running at PIO speed. Other than that though, the drive is perfectly fine....every disk checker, SMART checker, and diagnostic I have says there is NOTHING wrong with the drive. The SMART drive records don't indicate any read/write errors or seek errors for the life of the drive. The drive is only about 8 months old. It seems to me there are only 2 possiblities...the drive is bad or windows is screwed up. Please help if you have any helpful info for me, thanks.
