System nie widzi całej pojemności dysku twardego

Ok...problem seems to be solved.
After reading your posts and searching the web, it seemed the specific problem may be a compatibility issue between the Seagate drive and Gigabyte MoBo. So instead of pulling the drive and using a different machine to set Max LBA size, I booted to SeaTools for DOS on the UnRaid box. I checked the BIOS before SeaTools came up and the drive was shown as 500GB. In SeaTools it showed as 1.5TB without having to change any settings or run anything. I then rebooted to the BIOS and it now showed 1.5TB. On to UnRaid and it properly shows 1.5TB.
Whatever little glitch exists between the drive and motherboard, SeaTools seems to be able to fix. But you have to run SeaTools on that drive/MoBo combo to let it do it's magic. Not sure that really explains anything, but I'm happy if it works!
Many thanks for your help and support...as always!

Ja chciałam screen z zarządzania dyskami, znajdziesz to w zarządzaniu komputerem, w narzędziach administracyjnych, nie chce widzieć dysków, tylko partycje Poza tym wysłałam ci małą instrukcję odnośnie takiego problemu, poradzisz sobie z tym ? Tu bardziej chodzi o bios niż o samą płytę. Wyżej masz rozwiązanie.
