Ok, I just got home tonight to realize that my laptop hard drive is dead. I'm not sure if it is from overheating, or what, but I turned it off and am going to mess with it tomorrow. I am wondering how hard it would be for me personally to replace that hard drive with a new one. And if it is even possible to take that hard drive out and put it in my desktop and see if it is totally dead or what. My thoughts are that it got hacked and someone put a hard drive killer on it, because it has been working fine, without any problems lately. I hate to think this, but until I investigate a little that is the only thing I have been thinking about. Anyway.....If anyone has replaced or exchanged a laptop hard drive before I would like some input about how hard it is. I am very computer literate, and know a lot about them (desktops, never laptops). So this isn't a n00b job Or if anyone has any suggestions as to what I can do to check. Right now the only thing it wants to do is boot from the network. I enter the bios and my primary master isn't recognized, it says NONE. It is a KDS Valiant laptop. If you need more specs I'll look them up, but I'm sure it has nothing to do with that.
