Recently my HP Pavilion laptop died, and I had to get it formatted. Annoyingly, after doing so it is still being a pain and cocking up despite nothing being on there. I've come to the conclusion that my hard-drive may well be faulty in some way. It always makes noises that sound as if its trying to work but isn't getting there - and sometimes even makes high pitched beepy noises which sound quite scary. I've always thought that if a hard-drive was broken it wouldn't be able to do anything, but maybe I'm wrong. Whenever I try and re-format, the time it should take to load something in 10 minutes is taking about 3 hours, which is ridiculous.
So basically, I was just wanting to know whether its possible get rid of my old hard-drive, and to buy a new hard drive, and stick it in my laptop, and start a fresh from there. Is that doable or doesn't it work like that? If it is doable, do I need to get a specific hard-drive or are all hard-drives the same size/compatible with any laptop/PC?
