when you say partion drive, do you mean your active windows partition or c: or whatever? is your external drive a usb connection?Well it didn't do it previously...I suspect I may have changed a setting , when tweaking the PC for speed..
It only occurs when accessing the Partion drive or external drives or when opening a program that looks at these drives...

if you getting an error on your o/s hard drive, then as others say it could be stalling on bad sectors or something, or it could be a ****y connection (is it ide or sata?) check cable for damage etc.
if external drive is usb and your system hangs a little when accessing this then that could just be a usb sync problem with the external drive. i think windows xp presumes that the external drive is like ide or sata or something and expects it to behave like a normal hard drive, ive read somewhere that usb drives are obviously not as efficient as ide or sata etc and that they can have bugs.
you could simply be about to witness a hdrive meltdown and have a seperate slight issue with your ext drive due to usb. if your drive starts "clicking" then id back up whatever you can as quick as you can
