I have an older laptop that we use infrequently here in the office, and it's making a pretty loud grinding noise. I looked into this a bit on-line, and everyone seems to agree that this probably means the hard drive is going. I just want to confirm a few things with an expert before I proceed: 1) Is there anything I should try to get rid of the grinding noise before I just pack it in and trash this laptop? 2) Although the laptop is older, I really don't want to trash it. Does it make sense to buy a new hard drive? 3) If I do buy a new hard drive, is that the kind of thing that I can install myself, without too much experience? Can you guys help me through it? 4) Do you have any suggestions on where I should go for the drive and what I should get? (It's a Dell Notebook) Any assistance is very much appreciated!
