So, last year I lost my PC to a hard drive failure. Since it was out of warranty, I didn't bother trying to have it fixed and I bought a MacBook instead. Fast forward to now, I've been in need of a second laptop. Rather than buy another computer, I thought about fixing my old one. I looked into replacing the hard drive, and it appears to be relatively inexpensive and straightforward. But I've never really touched computer hardware before, and I'm afraid I won't be able to do it correctly. My question is, is this generally an easy repair? I know some hard drives aren't meant to be user replaceable, but after reading the manufacturer's guide, it looks very simple. Also, how can I be sure that I am buying a compatible hard drive? Any tips would be appreciated.
