A recent article on MacFixIt.com points to an Apple Knowledge Base document detailing how certain Intel-based Macs (namely the early 2006 iMacs and the MacBook Pro laptops) can become unresponsive if used as a host for FireWire target disk mode for more than 24 hours. Also worth noting is that the display and hard disk on the MacBook Pro might not go into sleep mode when Target Disk Mode has been activated for long periods of time, so be aware of this when checking if the system has become unresponsive.
Albeit a fix (either from a hardware or firmware update end) hasn’t been released, Apple suggests unmounting the host computer and restarting target disk mode sessions every 24 hours.
