i just got two LaCie 1TB externals -- one for time machine and one for media (iTunes, home movies, etc.) i couldn't see the hard drive on the desktop when connecting with Firewire 800, so i hooked up FW400 and ran the LaCie firmware updater, which worked fine on both drives. i was a little frustrated that the FW800 wasn't working, but i attributed it to the firmware being outdated. so after updating them the FW800 still doesn't mount both drives and the FW400 only mounts one of the drives (the one for time machine)! i don't think it's the LaCie, but it might be. the only thing i'm thinking right now is to hook them up to the USB and re-format them with Disk utility. i'm concerned that i won't be able to see one of the drives, and having to settle for FW400 when i have FW800 is ridiculous. any help? thanks!
