I recently decided to upgrade the main components of my computer(the cpu, motherboard, and graphics card) though i did not want to lose any data on my old drive (I read that a new motherboard almost always requires a re-installing of windows) so i got a new one.
What i am wondering is if i get the new parts all installed and working properly, can i use the old drive as a secondary storage along with the new one, At least to the point where i can move over the music and pictures? And they are both using windows 7 from a store bought disc.
