I've recently migrated my iTunes library onto a firewire 400 drive, namely a iomega ego 500gb drive. Previously it was on a Freecom USB2 drive... i never had problems with the USB but thought the firewire would yield better performance for hosting the VM's i use and overall disk performance... Problem i have is that periodically the drive just seems to unmount without warning.... its happened about 6 or 7 times... I have formatted the drive as a Journalled drive so i'm hoping i won't be in danger of corruption ... Is there anything i can check (similar to the windows event viewer?) to see why this is happening? I'm relatively new to mac problem diagnosis ... this is actually the 1st time i've encountered a problem since i got the mac.
