Running 4.7 at last. When 2TB drives are $80, you just replace them. Took about 16 hrs to rebuild. I will attach the hpa drive to my pc and fix it from there and then add it back again. Thanks for your help.
Lime, y'know when the bootloader loads it asks for your selection for unraid or memtest, how about putting a program there to check and remove any HPA issues? Sounds like a winner to me!
