This is weird. 240 is probably the same as 254 (depends on the drive, check
the datasheet), but even if it is _not_ the same, it *must* activate a
deeper power management mode (i.e. one that is more effective/aggressive)
than 254 does, so if anything, it should increase the amount of
unloads/tickings...
