Get one with firewire, sometimes available at the same price as USB ones. Firewire is straightforwardly bootable in X or 9, and *much* faster, and is fine as bus-powered from an iceBook. AcomData has a nice empty external housing for 3.5" HD which has both firewire and USB, which lists at approx $50 (?) at CompUSA but occasionally is on sale. AcomData also has USB-only, firewire-only, and fw/USB external HD in various sizes which are often on sale at quite reasonable prices. One I had in frequent use in a too-warm place started making a slight HD whine after a couple of years (not complaining, my fault for the heat, which I corrected), and when I took it apart I found the HD was a standard good quality Hitachi (and found also that the fan bearings were failing which hadn't helped the heat issue). I don't hold the fan against the company, and have bought or specified several more AcomDatas. The empty externals are fanless, too. On Mon, 25 Sep 2006, Steve R wrote: > Thanks for the feedback.
