Hi, I'm new to the forum and I apologize if this has been asked before. I have a 1.83 GHz 13" Macbook with its included 60GB HD. Over and over, I have found myself running out of space on my hard drive as I do a lot of video editing. A friend suggested that I upgrade my hard drive, however, I'm not really sure how to go about doing this. Will a hard drive from a supplier other than Apple work in this laptop? Are there ramifications or parameters for my specific model? Also, any hard drive suggestions would be greatly appreciated. Thanks.
