Stack Not sure this will help but heres my 10 pence worth
EDD being related to Disk drives this makes me wonder if the correct firmware is being used but it did somehow eventually get around the issue eventually - any way you can try say a different hard disk? Can you boot a live disk on the machine with dare I say it another distro ISO on usb or cd - I would try a full centos or redhat first then try debian flavours and if not the ever last resort knoppix if so maybe there are drivers or settings you can try - this will aleviate the isue if its the hard disk firmware causing the problem! If the cd works try a different hard disk maybe Paul On Thu, 2017-02-16 at 22:07 -0600, ~Stack~ wrote: > Greetings, > > I'm going to keep this "short" because I've just had 6hrs of things I've > tried that didn't work.
