Disk Drives keep going to PIO...
My brother's computer started having problems with the disk drives(2) working, well, slow.
Bear in mind, this in only verified by phone conversations.
It kept downgrading his disk drives from DMA to PIO.
He tried uninstalling the IDE controllers, then reinstalling them.
Then he replaced the IDE cable, assuming it was a bad cable.
Then he, without my consent, messed with the registry to get it enabled.
Then when it still didn't work, he reformatted the computer.
It is still apparently set to PIO. Any suggestions?
Check the BIOS.
Download the hard driver manufacturer's tools and scan the hard drives for any issues (SMART, firmware, etc).
Jumpers, 80wire cable (not 40), UDMA compatible drives (it will revert to the slowest setting on the channel if only one drive can handle DMA, if I remember correctly) are the only other thing I can think to check. :S
Windows does have a thing about after so many errors, it sets the drives to PIO mode and you can't set it back without a registry hack, uninstalling the controller (sometimes works...), or using a force program (dell has one for their computers). Goofy shit. The re-format should have solved that though... and if it did... well this is where you wish you had spinrite.
