[djblade]

As header, 1 of my three hard drives has suddenly gone to snail pace, run anti virus, and the adware programmes, and nothing untoward is showing up...

if i write/read from the other two drives things are fine, but if i try to write to/from the affected drive, things crawl.....

any idea's ??

took 2 hours to reauther a dvd to c drive, and 17 mins to the other 2 drives.... just happened overnight, nothing changed, to my knowledge..

tia guys....

Have you checked to make sure one of the controllers hasn't kicked into PIO mode in device manager?

[ROF]

When was the last time you defragged the drive?

[djblade]

Sorry, should of added, i defrag every 12 hours.......

please remind me how to check for pio mode.....

[djblade]

gee, yes, the transfer mode is set to pio, cant see a way to change it.......

wonder how the hell this happened......

Pull the drive controllers from device manager and reboot. They SHOULD reID and leave PIO mode at that point.

XP will kick into PIO mode if it gets a specific number of errors. It happens with DVD burners all the time.
