Thanks for the help guys.. Thing is, i was quite afraid to reformat over it cos the general consensus was that it will only worsen the problem. The partition had 420GB of its 488 capacity used up (Seagate 1TB barracuda HDD)
So i chickened out and got some professionals to do it. Pretty straight forward job.. cost me 150 dollars.. singapore dollare that is.. which is like 100 USD..
had really important data in there so couldnt risk it =P
