I have 5 external drives... They are Seagate and Western Digital Drives. The worst of the bunch is the Western Digital My Book Studio Edition (1TB) that I have connected via FW800. The 2nd worst offender is the Seagate 750GB Free Agent connected via FW400. The most dependable appears to be a Western Digital USB drive, but it's the slowest performer. The issue is this: I either have a freeze up that requires an unplug from the Mac as well as power, then re-mount to get working again, OR, when I start up the Mac, it just hangs at the 'apple' and never fully boots. I have to unplug the drives and boot, then plug them back in after the boot. It's getting very frustrating. Do you all have a successful setup with external drives? Is LaCie the way to go? Is it because WD and SeaGate suck?
