Hitachi HD keeps on reverting back to PIO Mode

[dannylu88]

Hey Guys, I bought a Hitachi 500gb Desktar Drive about a year ago and I recently put it in a system I just finished building. The thing is that it seems to keep on reverting back to PIO mode after every restart. I know about the uninstalling the Ide channel/controller and it does work, but it is just annoying having to do it after every reboot.

I seem to only have this problem with my Hitachi drive. My other drives (WD, Maxtor) are both fine.

Does anybody else experience this same problem?

I have a Asus p5b-Deluxe Motherboard.

Thanks
-Dan

cable?

With CD-ROM drives, this will happen if the CD-ROM drive gets too many read errors. Any Disk errors in your System Event Log?

Read errors will do it to any ide drive.

I would replace the cable, verify the settings in the BIOS, and then update the chipset drivers.

Run DFT on the drive to look for errors. That's usually the sign of a drive having problems.

try changing the cable and check the event log for errors. this is usually a sign of a failing drive.

this is a good read and very helpful. it also has a script that forces the data error counter to be reset helping the drive stay in DMA mode.

Hi guys, I'm sorry but I am a total noob, what exactly does DFT mean? and now my hard drive doesn't even go into PIO mode anymore, just recently it starts going into "Multi-Word DMA Mode 2" I never even saw that before.

The JMicron controller included on your board defaults to PIO mode often. I would update its drivers or use another controller. I've had tons of trouble with the JMicron on my DS3.

I have a CD drive hooked up to the JMicron and it froze my PC just randomly (weird interrupts). Glad to have disabled it.

The registry fix on restetting the counters is useful.

hmm.... thanks for the suggestions guys... but i checked my disks for errors while booting up and it works now.... i guess i just never checked my hard drive.
