Disk Utility won't format / erase Seagate Barracuda 2TB (ST2000DM001) - it is an internal drive but I connected it using a docking station via USB. The disk is brand new and unformatted. System indicates that it is S.M.A.R.T incompatible


When trying to erase the disk, I get error message "disk / link could not be found / opened".


I tried using terminal "diskutil eraseDisk HFS+ newdisk /dev/disk3" but I get this message:

Started erase on disk3

Unmounting disk

Error: -69877: Couldn't open device


Any way I could force format the disk?
