Hi guys, On black friday I bought a new Dell laptop. it's supposed to have a 500 gig hard drive well, when I click on computer the OS (c hard drive says: 423 GB free of 451 GB I have nothing installed on it besides what came from the factory so where are my other 49 GB? I willl probably never use up all that memory but if I paid for 500 GB, I want 500 GB. Wanna kill these ads? We can help!
