lately i have been having a few system crashes and i get that "your system has recovered from a serious error" message when it restarts. i have found that it is somehow linked to my external HDD. i have an oxford IDE IEEE 1394 SBP2 80gig external hard-drive. whenever i try to run a scan disk on it...the system crashes, computer restarts and i get that same message. any help would be much appreciated. cheers.
