So, hdparm did no good.
Did you try sdparm? Serial ATA looks like SCSI to some tools.
Nope, because there was no sdparm. For some reason did not think to
check if such exists at all :)
This is what sdparm gives but I don't have the knowledge to find dma
specific info in this. I see that there is something about dma but is it
enabled or not??
