This > could be caused by an out of spec 12V supply ... uh-yup, uh-yup, dat'z da one... clear a spot on yer coffee table.. you have definitely got a new conversation piece if you can get the cover off... as well as a sad story to tell. actually i was never sure if it was a stepper problem or a head melt, it was a barracuda, and seacrate hadn't yet fixed the barracuda head melt problem.... btw: it is an unwritten law that one will never be present to see this message in real-time... call it a gift from god at a bad time. i had just got home from work when i saw all the kernel printf's. i was too tired to get really pissed and commit hari-kari over my lost projects [that i had just made a major breakthrough on that morning]... M-A-K-E M-A-N-Y M-A-N-Y B-A-C-K-U-P-S !@# BTW: that last warning nevuh sticks until you get the above kernel printf's!!
