I took an old laptop hdd connected it up to my Mint box and ran sudo dd if=/dev/zero of=/dev/sdb ran for a few hours until complete. Connected the drive to n4f box then did disk>management>import disks and there it appears all the information >>>>filesystem Unknown or unformatted, bonus
N4F used is latest 10.2.0.2.2332, I'm obviously missing something or have not prepared the latest hdd correctly and any pointers would be appreciated.
