Yes. It's not hard. Here's some comments:
1. Be careful with all the parts. Don't force anything. Touch something metal every few minutes to avoid frying something with static discharges. There aren't very many parts to work with in a laptop but they all go together really closely.
2. Back up your data on an external hard drive. Do this before anything else. If you don't have one, just buy one. They are quite affordable now, especially low capacity ones. If you don't do this, you may lose your applications as well. Most of the drives come with software that will help you do a backup. There's no need to pay extra money for backup software. If you back up your drive, you won't need to reinstall windows either.
3. About the best brand available is Seagate. Maxtor isn't bad either. Western Digital and iomega aren't known to be as good as Seagate. Toshiba may be good. I don't know. Do a google search on laptop drive reliablity.
4. If the existing drive is already fubar, try and find all the cd's that came with the laptop when you bought it. You may need drivers or software that standard windows doesn't have right off. this is especially true if you've added a wireless mouse or a cam or other peripherals. If you can't find them, download them from the manufacturers websites and have them ready before you start.
5. Try to do this when nobody, and I mean NOBODY else is around. The worst thing in the world is getting interrupted, going away, then coming back and losing track of where you were. Or trying to concentrate deeply while someone is trying to talk to you, or needing help or attention with this or that. Alot of people really don't understand that even if this isn't hard, it takes concentration and patience. The exception here would be if you have a friend that is an supergeek and could help. Keep an eye out for the ones that really know their stuff versus the ones that talk a good game, and will get in the middle of your business and mess it up worse.
All that being said, this is not a hard thing to do at all. Just try it and see what happens. If it's already busted, or if you have it backed up, you can't really mess anything up unless you fry it with static, force something that doesn't belong, knock something onto the ground, or spill your coke in it. Bottom line, long as you are careful., there's nothing to lose.
