I read a few threads about HD crashed, worn out and other problems. Also some of you mentioned about the average life of a hard drive maybe around 3-4 years depending on the usage.
My question is if I had a problem with my HD and I know for sure because it has worn out, is it worth to send it back to the company where I bought it and have them replace it? Or might as well buy a new laptop? I have this one notebook that I prefer to keep longer and it's 3 years old now.
I know many people upgrade and replace HD themselves for their desktops, but how about notebooks?
