External Firewire Mirrored Raid on MacBook Pro Causes Kernel Panic

Last Modified: 2013-11-24
I have two identical FireWire/USB2.0 External Enclosures from Macally and they each have identical 500gb Maxtor drives inside. They are hooked up through a hub (and I've tried daisy-chain) into the MacBook Pro FireWire 400 port. Whenever I create a mirrored raid in the disk utility, it causes a kernel panic and the system freezes.

I'm not sure you can create a RAID in such a way.  It is not a very stable or reliable infrastructure for RAID.
RAID drives should usually be in the same enclosure and connected to the same bus not in parallel or daisy-chained on a Firewire port or even through a hub is a bad idea..

Did you see any information from others who have done the same?

My response still stands .. I am sure that daisy-chained firewire drives are not suitable as a RAID configuration.
