I will try the new drives when they arrive.....Things seem to happen to me that are just silly, if you know what l mean. A prime example is the note pad scenario that happened a while ago, it wasn't configured for config files. Hence the clines weren't recognised in the box. It took ages to sort that one out, that was down to a pc windows upgrade. Things seem to happen just to give us a challenge. lol. As the saying goes you live and learn.I must flash my duo2 10 times a month messing with stuff, never any issues main thing is make sure you remove any usb kit so the only usb drive it will be using is the one your flashing with.
