How to fit an 2,5" PATA HDD in 3,5" HDD case

Yesterday I got a computer that had a broken HDD. I had a 2.5 "HDD, so I decided to install it in computer, but it's too small, so i put it in 3,5" HDD case as follows:

Required items:
-broken HDD (3,5")
-workable HDD (2,5")
-2,5" to 3,5" PATA HDD adapter (http://www.ebay.com/sch/i.html?_from=R40&_trksid=p3984.m570.l1313&_nkw=%09+2.5%22+HD+to+3.5%22+IDE+Hard+Drive+HDD+Adapter&_sacat=See-All-Categories)
-a smal saw
-Hammer

WARNING, do not squeeze, bang or shock HDD, otherwise you will break it!

Step 1 Disassembling HDD

To disassemble the HDD you need to unscrew the top screws and remove the top cover.
The steps are shown in Figures.

You can get adapter mounting rails to do it properly since you did not shock mount it in the case. The old harddrive case would trap in the heat and eventually put excessive strain on your drive unless you ventilate it at least with holes..

Since the case is made of aluminum, part heat spreads through him out.

yeppers... the old hard drive acts as a giant heat sink!
More evidence is given by the VelociRaptor hard drives.

also, since it's hard-mounted to the old drive... any shock mounting form the external case is re-used... so no additional absorption is called for.
