My laptop was having issues and i had to use my recovery disk. but my c: Drive was full so i had to use my D: Drive.. now can i delete the ones of my old C: drive since it was from before my recovery? or are they needed? and if i can delete them then how do i switch the drives because the current drive with all the info on it has 250 gigs on it and so i want to use that for other things. So can i switch the drives or do i need to recover again after i remove the uneeded info?
