as dbow says, the black USB external drives are called Passport and have a SATA Scorpio drive inside. I've done two. Easy. Use something to pry with, like a credit card or screwdriver. Its kind of tricky to do it and leave the case looking completely new, which is what I tried since I sold it on CL after replacing the 320 with an 80. Got the 320 for $125 from buy.com and sold the 80 for $60. Pretty cheap upgrade.
