Re: installed hd tune on a whim and it failed two tests. what does it mean???
If HD tune found a problem with a hdd on your laptop, your drive might be beginning to fail.
If you know what kind of hard drive you have in that laptop, download the manufacturers diagnostic tool, and see what it says.
If it's getting ready to give way, you need grab some dvd-r's or a 4gb or 8gb flash drive and start backing up everything like mad.
ALso laptop hdd's on newegg aren't that expensive but they cost more than a regular desktop hdd and depending on what size you want.
