My wife's Inspiron 17 5767 started making HDnoises.....tic tic tic......until it got louder and louder then failed completely The laptop was still under warranty so I sent it back to Dell....they replaced the harddrive and sent it back. It's only been two weeks and the hard drive is making the same noise again....tic tic tic. Well before it went all the way out I bought another hard drive and loned the laptop HD......I then put t the laptopn and guess what.....tic tic tic. So I got the hard drive that Dell"replaced" stuck it in a dock and it didn't make any tic tic tic noises....ran quiet as it should. Now, my question for you geniuses.....what other hardware would casue the harddrive to go out ?? I want to figure it out before I contact Dell again. Is it the MB ???
