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?
