Bug#419175: linux-image-2.6.18-4-686: USB HD gives I/O errors while spinning up

[Matt Reynolds <matt@mdr.me.uk>]

To answer my own question .. to restore power save operation:

# sdparm -a /dev/sdb
    /dev/sdb: Seagate   FreeAgentDesktop  100D
Power condition mode page:
  IDLE        0  [cha: n, def:  0, sav:  0]
  STANDBY     0  [cha: n, def:  1, sav:  0]
  ICT         0  [cha: n, def:  0, sav:  0]
  SCT         0  [cha: n, def:9000, sav:  0]

# sdparm -D -p 0x1a -6 /dev/sdb

# sdparm -a /dev/sdb
    /dev/sdb: Seagate   FreeAgentDesktop  100D
Power condition mode page:
  IDLE        0  [cha: n, def:  0, sav:  0]
  STANDBY     1  [cha: y, def:  1, sav:  1]
  ICT         0  [cha: n, def:  0, sav:  0]
  SCT       9000  [cha: y, def:9000, sav:9000]
