DMA Mode [Auto]
DMA (Direct Memory Access) allows your computer to transfer data to and from
the hardware devices installed with much less CPU overhead.
The DMA mode consists of SDMA (single-word DMA), MDMA (multi-word DMA),
and UDMA (Ultra DMA). Setting to [Auto] allows automatic selection of the DMA
mode.

and Reporting Technology).
[Enabled] Enables the S.M.A.R.T feature.

32Bit Data Transfer [Enabled]
[Enabled] Sets the IDE controller to combine two 16-bit reads from the hard disk
