Last night I attached a self-powered native formatted external hard drive to a USB port and it froze the machine - this is not usually a problem. I had to disconnect the mains to restart the computer, but on doing so I got my first ever 'pyjamas' incident with vertical fine coloured stripes in repeating sequences across the screen and the monitor complained that is was not being fed an optimal resolution. I've tried all the usual tricks to get it going again, swapped PSUs (twice) but no change. The floppy drive light comes on, the internal discs spin up and the nothing else - no sounds to indicate that the boot sequence is proceeding, just a bricked machine. I checked the supply voltages on a spare drive power plug as 5.09v and 12.08v with a DMM. The Iyo is running on 5.16 flashed with a later (FX5200?) graphics card. Luckily the nightly backup had run about 30mins earlier and I have BeagleBoard, so I copied Messenger and NewsDir across so I still have access to mail and news.
