I just bought a 200GB Maxtor External HD today. Prior to this I only had 1.62GB free on my PB. Now, I'm new to Macs so bare with me... I went into my PB's applications folder, and dropped everything I want on my external in the corresponding spot, I then erased the applications from my PB's HD. However, when I restarted my PB, my PB HD still said I only have 1.62GB free? Am I doing something wrong? They were big applications too, i.e., Final Cut Pro, DVD Studio Pro, etc. I'm currently moving all my music onto the Maxtor i.e., 4000 songs. Can someone help!!! Wait, another thing..the applications I moved onto the Maxtor are only applications I will use while at my desk, so should I delete them from my dock?
