i'm going to purchase one for someone with a laptop. i'm curious if anyone has any advice to give that i might otherwise not take into consideration until it's too late. anything i should know about these things. requirements: - must be firewire - 3.5", not 2.5" or 5.25" - fanless is a big plus - must stand vertically - not expensive (ie. no more than $60) - oh, and empty (if the previous bullet didn't give that away) some general questions: - will the harddrive automatically spin down when the computer is turned off? is that possible over a firewire interface? - the ones with fans; are they always on, just when the comp is on, or temperature controlled? some i've eyeballed: - Bytecc ME-350F - Argosy HD-360C - Coolmax CD-309-FW and, of course, i'm open to other brands and models. thanks, guys.
