Hi guys, im experiencing a problem here and I hope someone can help 

My computer has been working well until recently transferring speed of files became very slow, for example 250mb will take up to a few hours. And also loading of video clips inside the HDD is also a problem as the videos would not load properly, stopping every now and then as if it was buffering.
I went to do a bit of research myself and used the HD Tune to check my HDD and it came up with these results.

Image - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting (HDD Benchmark but wasnt able to complete due to some errors)
It says I have reallocated sector count, which from what I found online, it cannot be resolved.
Therefore is my only solution now is to change a new HDD??
My Hitachi HDD is still under 3yrs warranty which is bought in 2012, will I be able to exchange for a new HDD?? or warranty does not cover such things. The HDD was bought from PC Themes.
Will PC Themes be able to exchange 1 for me? Or will I be able to RMA the HDD?
Thanks for taking your time to read and I hope someone will be able to help me
