I have a 2010 macbook pro which, sadly, suffered a (suspected) hard drive failure. I was kindly gifted a brand new macbook, but am considering buying a HDD to replace the faulty HDD on my former model. The apple store couldn't be 100% sure that it was a hard drive failure, and it was going to cost a lot of money to find out exactly what caused the machine to stop working, however they said it was most likely HDD failure based on the test they did in store. I am looking to buy a cheap, but still attractive to potential buyers, HDD which fits the model, and am hoping to install the drive myself using youtube tutorials. If possible, I'd maybe like to buy it somewhere that I can return it, if it turns out to be redundant (that is, the macbook failure wasn't attributed to a failed HDD) Any pointers as to where to look and price ranges would be appreciated! (novice!) thanks.
