hi.. donna if this the right place to ask this question..
my question is usually how long the lifetime of HDD..
in past 3 years my pc mostly turned on but lately my pc feel very slow.
does my HDD already reaching it limit ?

If possible i will try to avoid reinstalling windows.
This because i have many game in it and don't even have their installer as backup.
If i buy new HDD, can i use it with my older HDD in windows and keep it without reinstalling?

I have tried Linux before but don't quite like it..
I admit that Linux feel smoother and faster but i find that quite difficult to use as daily use compared to Windows and OS X.
