root@MyBookWorld:~# hdparm -B255 /dev/sda

/dev/sda:
 setting Advanced Power Management level to disabled
 HDIO_DRIVE_CMD failed: Input/output error
 APM_level      = not supported

root@MyBookWorld:~# hdparm -B254 /dev/sda

/dev/sda:
 setting Advanced Power Management level to 0xfe (254)
 HDIO_DRIVE_CMD failed: Input/output error
 APM_level      = not supported
