The first drive in my Inspiron 500m was the the included 4200 RPM Hitachi drive. It had the problems listed here.
I received a new identical drive from Dell, but the problems didn't disappear. This made me believe that the chipset was the source of this problem. Until now. A couple of weeks ago I switched to a new 7200 RPM Hitachi drive bought from a third party. All DMA problems disappeared. There can, as I see it, be two reasons for this: 1) I received two faulty hard drives from Dell. 2) The chipset had problems with the hard drive models I received from Dell, but not with other drives. I don't know which it is. I had no problems with the "faulty" hard drives when I tested them with other fairly equal computers (one year older 500m and one year newer 510m). Maybe a overly sensitive chipset? Anyway, I'm just happy I have a working computer again. Henrik -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
