Hey i have a toshiba equium m70. I need to upgrade the harddrive. Just wondering....in PC's there are different types of harddrives...SATA and IDE mainly. Does this apply to laptops? I know its a 2.5" harddrive....so is that all the info i need? Will every 2.5" harddrive be compatable? Thank you, just a quikie. Let me know.
