So, Tiger has been about 90% good for me. I had a serious episode with iTunes and my iPod plugged in over USB 2.0. I had to reboot my computer twice yesterday because iTunes would stop responding, yada yada. That's a different issue though, that I have since taken care of. However!, since Tiger, I notice that sometimes, with fast-user switching, or even just logging out of my account, and then logging into a different account, my firewire drive just disappears. It stays powered on, but it won't mount. The power light is on, but no drive. Also, if I haven't accessed it in a while, say, 30 mins, when I go to access it, I just get the beachball, and the drive never actually spins up to speed to access data. I discovered I can just trick the OS and unplug/plig in the drive nice and quick, and suddenly it's accessing for me, but, it's quite annoying. So...ummm, yeah, It's a bus-powered firewire Toshiba 60GB 2.5" notebook drive. THANKS! What say ye?!
