Almost all Toshiba (old and new) have a HDD that is only one screw away (except 1600's, 1700's (35 screws), 1800's. I take that back, most Satellites and Sat' Pro's from the past 2 to 2.5 years have two screws, though neither is absolutely necessary. The Acers I have seen all have one screw and the few Compaq Presarios that I have seen have (8) screws to remove the HDD. Compaq's business laptops only have one screw (from my limited experience) but are of the torx variety.
