As the title says i don't understand why all my drives whenever accessed for a good amount of data get "The driver detected a controller error on \Device\Harddisk2\D." in the event viewer and eventually switch to PIO mode. Originally i thought it was on one channel that has a 200 gig drive and a DVDRW on it but now i noticed it does it on my other channel with two 80 gig IDE drives as well! My voltages seem as stable as they were months ago before this started happening. Ideas?
