I also have the same issue..
I observe that DMA is not enabled on my HDDs and I'm unable to enable
them using hdparm. I have no idea how to accomplish the same using sdparm
As a result, the drives are running slower.
Apparently, this due to the conversion of HDX to SDX (hda to sda) in
recent Ubuntu releases. Not sure when this started, (I'm tried the Temp
fix but still the drives come us as sda..sdb ...).
Some info below on messages I get:
