My hard drive is failing in my HP Envy 14 Beats Edition and HP screwed me out of my warranty so I will have to replace it myself. I was just wondering if anyone could lead me in the right direction to get this done. I'm not sure what size hard drive i will need to buy and if it matters what kind, im looking for atleast 750gb+ since thats what I have now. If there's anything important I should know before doing the replacement, or anything else I should do while I've got it apart, I would appreciate the help. Thanks!
