Re: [gentoo-amd64] HDParm recommendations

Right. Try sdparm instead:

lightning ~ # sdparm /dev/sda
    /dev/sda: ATA       ST3250823AS       3.03
Read write error recovery mode page:
  AWRE        1  [ sav:  1]
  ARRE        1  [ sav:  1]
  PER         0  [ sav:  0]
Caching (SBC) mode page:
  WCE         1  [ sav:  1]
  RCD         0  [ sav:  0]
Control mode page:
  SWP         0  [ sav:  0]
lightning ~ #

I don't know how to use it, but it's there... ;-)
