If your HDD is making noise, it is most likely damaged in some way and needs to be swapped out immediately. You most likely cannot backup any files from a corrupt HDD, but if you manage to, that's nice. However, if it's too damaged you can't simply replace or fix any parts of the HDD. You will have to buy a new one.
I disassemble computers, laptops, tablets, and phones. I suck at taking apart devices any smaller than 11.6". They tend to be tedious and straight devious. Other than that, if I have a problem, it's unfixable because I know what I am doing.
