It might be a good idea to mention sdparm for SATA hard drives next to the part explaining tuning up the hard disk with hdparm, which only works for EIDE drives. Since hdparm used on a SATA drive gives very similar errors to the ones when one tries to enable DMA with hdparm but lacks the proper drivers, this might be useful for new users. Reproducible: Always
sdparm is not included on livecds or other installation media, so we can't talk about using it. also, SATA drives are different than ATA drives; they don't need tuning the way ATA drives do; they're designed to run at their designed specs out of the box (never needing user intervention), whereas often enough things like DMA, readahead, and sector count on ATA drives need to be explicitly enabled.
I see. How about adding "only ATA and not SATA hard drives" to that passage? Forget about sdparm...
