Nope. atacontrol returns information about a drive's capabilities, but off=
ers=20
no way to change the settings that affect them. Example:
# atacontrol cap 2 0
[...]
write cache yes yes
read ahead yes yes
dma queued no no 0/0x00
SMART yes yes
microcode download yes yes
security yes no
power management yes yes
advanced power management no no 0/0x00
automatic acoustic management yes no 254/0xFE 128/0x80
shows that read ahead is available and enabled, but I don't have a way to t=
urn=20
it off. tunefs only affects a filesystem's attributes but not the underlyi=
ng=20
hardware.
