Harddrive stuck in PIO

[Wihln]

Ok, my harddrive is stuck in PIO.. it's a nightmare.. its a Seagate harddrive baracuda V .. And i've tried pretty much anything i can think of.. Registry-changes, "reinstalling" ide, + alot more and general trial and error.. :S can someone help me? It's supposed to change back to DMA when i do the changes but its stuck.. i searched on google and found a lot of people having the same problem.. Apparently its fixed in SP2 (i use XP:home) but there should be a way to fix it.. :S does anyone have a solution

I don't know if you've tried this or not, but I had the same problem with Windows 2000. Deleting the IDE Controller from the Device Manager and then having Windows reinstall it seemed to fix it for me.

I think that's what he meant by "reinstalling ide"

You've probably tried it, but have you played with the drive settings in your bios? Ie setting the drive instead of having it set to autodetect?

I had a very same problem.. I solved it just like most OS related problems - format c: ..how old is your current os install?

 

[Wihln]

ultraright - yeah that was what i meant when i wrote "reinstalled ide" =) sorry, my english isn't that good.

TheMostWantedPolishTwin - About 6 months old. (i've had this problem for over 6 months. I did a format c: and reinstalled windows, didn't work:[ )

SoulkeepHL - Done. Doesn't work.

You see? =(
/me goes insane

If Windows didn't f*ck up (again), then you should look at the following:

- BIOS: UDMA should be enabled for all IDE channels;
- cables: make certain you're using an 80-conductor (66/100/133) cable. Use a different cable to ensure that the current cable isn't damaged.
- try a different IDE channel.

So what mode does the bios say the drive is using? If the bios says the drive is using PIO then it isn't an operating system problem. Change the cable. If that doesn't work then it might be a problem with the drive or the hard drive controller.

everything is in order ... still PIO =(

Take a look here and see if this helps.

i have that same problem on a computer too.. i reformatted 3 times... once for win2k, XP, then XP again with SP1. i tried swapping the psu, cables, resetting bios... . right now the comptuer is sitting on the floor, i am about to take that damn motherboard out and burn it...

oh, and it did it on 3 different hard drives... so if anyone has a good pentium slot 1 board that they can sell me, i think i am going to go with the burning idea..

but i would be interested in knowing how to fix this if possible...

and i remember reading that above article... but i tried this with multiple hard drives... oh well...

Had the same problem last week...

Turned out to be a bad cable.



Read your system events; if there's a bad cable forcing it to fall back to PIO, you'll see an assload of errors.

as Eigtball pointed out above
IDE ATA and ATAPI Disks Use PIO Mode After Multiple Time-Out or CRC Errors Occur

and I'll add
DMA Mode for ATA/ATAPI Devices in Windows XP
also located in the Physical Configuration Section of the Partitiong and Optimizing Tutorial in the Data Storage FAQ

and an excerpt from it

there is a myth about putting optical drives on the same channel as HDDs, it is just that a myth, but it keeps getting reinforced by the way Windows deals with ATA\ATAPI issues
basically with Independent Device Timing two devices (master\slave) both transfer their data at their own highest speed, but, they both either have to be PIO (which is glacially slow) or UDMA, if one defaults to PIO because of some issue, Windows will default the other as well. There was a time when CDROMs where only PIO, and HDDs where DMA, for that period of history you didnt want to share a channel, but modern opticals are UDMA mode2 so there is rarely any issue

some of the reasons a device might default to PIO
DMA Mode for ATA/ATAPI Devices in Windows XP (same as above)

so is it on that channel by itself?
and recheck all your jumpers, making sure there isnt a HDD jumpered single with a slave present (or Master w\ slave when there isnt) and that all masters are at the end of the cable

also review the Corruption 101 FAQ regarding what could possible cause multiple CRC errors and timeouts (Primarilly the cable section)
Id try ATACT on that cable, and look at the routing, and reload the busmaster drivers
(the main mobo\chipset driver) Device Manager > Expand IDE ATA\ATAI Controllers > Uninstall the Busmaster, Primary & Secondary Channels (Driver Tab > Uninstall) , and reboot forcing it to reload, failing that find the latest driver for the mobo at the manufacturers site and run it (for instance if its a VIA Chipset, that would be the Hyperion 4 in 1)

and finally have you run the manufacturers HDD diagnostic?
