MFT (master file table) error after 15 months

I am doing the same.

I was wondering that by using only 100 gig for win 7 would I be increasing wear and tear
on selected part of the hard disk?

No, there is (hopefully!) no physical contact between the heads and
the platter surfaces. You're simply changing the magnetic orientation
of specific areas of the platters. There's no location-specific wear
involved.

BTW, if the heads ever do touch any of the platters, you'll probably
know about it in short order, and in a bad way.
