Methods of quick and dirty recovery are to manually spin the drive past it's stumbling point, by exerting clockwise centrifugal force on it.
In other words hold the drive, with one hand, fingers on one edge, thumb on the other and twist your wrist, fast. If you are lucky it will spin up and become active, if it works, GET ALL THE DATA OFF NOW, do not expect this to work more than a few times.
There is also the freezer method, put the drive in the freezer for about 30 mins, take it out, leave it in a cool dry area for about 5 mins, and try powering it up again, if it works, GET ALL THE DATA OFF NOW.
If the data on the drive is critical you must send it to professional data recovery specialists. Preferably one that offers a no fix no fee service, or a similar concession.
Disclaimer:
I've used both of these methods in the past, and had a reasonably good success rate, however, these methods are by no means guaranteed to work, and could damage the drive further making professional recovery efforts difficult or perhaps impossible.
YOU HAVE BEEN WARNED.

The "tic tic tic" is most likely the actuator arm (or what controls it) has failed. The best and safest thing to do at this point is to send the drive to a hard drive recovery specialist. This is especially true if the data is truly as important as you say it is. There is no point in risking damaging the drive, and subsequently the data, even more using "tricks" that have been known (or not) to recover a hard drive.
