My 250GB hard drive is about to fail and totally full, so I am looking at buying a bigger one. I have lot of movies and songs on my hard drive and want them on my new hard drive. I can't decide whether to get a nice 1TB or a cheap 2TB. I want to use it as my main hard drive. Can anyone give me some advice on what hard drive should I buy? BTW my budget is under $75. Thanks..
