My harddisk clicks. Is there a method to repair it?

I have two partitions. The first partition works. If I access the second partition, the harddisk gives audible ticks, and Windows tells me there is a cyclic redundancy error and sometimes offers me to reformat that partition. So it seems the drive spins up fine, but can't access the second partition because of a physical failure.

Because of the clicky sound the harddisk gives me, I know the harddisk is broken. Although I'm still able the access the first partition (with Windows on it). If I stop using a driveletter for my second partition, Windows runs fine. As soon as I link a driveletter again to the second partition, and access it, it's getting slow accessing it, which it can't, and the drive starts clicking again. It does several tries, then Windows and the harddisk give up and Windows come up with errors like above.

Questions:

1. If the error only occurs on (the end of) the big 2nd partition: what if I would chop that partition in two parts, and try to salvage files from the first part with a file repair tool. Could that work? Windows would probably want me to format the new partitions, but then ofcourse I'm sure all data will go lost (well, a quick format might not harm the files).

2. For a normal person, it is probably not possible to open the harddisk and put the magnetic discs in another disc closure (so I would have to open 2 drives, and close 1)? (I have no clean room, and no special tools.) Getting this done by a specialist drive repair company, is way to expensive...

I'm not comfortable to put in the fridge... I can try, but I don't expect it to get better (it might even get worse because of condens).
