Bug#321409: Problems gone after changing hard drive
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
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.
