It's worth noting that you'll need the libata passthrough patch to make
this work on a T43..

However, with this patch I'm getting the "head not parked 4c" message,
but I can hear the click from the drive.. It takes around 350-400ms for
the command to execute, but when repeated, it drops to around 5ms for a
short while (with no audible clicking), before reverting to original
behaviour after a few seconds.

The clicking and the variation in execution time lead me to think it is
parking, but not being reported correctly?

Jon,
