I'd like to know if I can upgrade the hard drive on a Compaq Presario 1500T to one of the IBM 5400 RPM 60 GB drives. I can't find a definite answer and would like to know before I purchase the notebook. I'm trying to decide between the Presario and an IBM A31 and am leaning towards the Compaq because of the integrated USB 2.0 and Firewire ports. What do you guys think?
