I'd like to get a low profile (ie small) external hard drive to sit with my Powerbook and host my iTunes library. Ideally it would be bus/FW powered so as to avoid the need for a second power cable. I've seen complaints about the Powerbook not delivering enough power to drive Iomega, La Cie and Western Digital mini drives and would love to find someone who has one running bus/FW-powered from their Powerbook with no such problems. I was looking at the La Cie Mini Disk or one of their rugged disks or the WD My Passport, but would look at other brands with good reps. TIA
