   I don't know what your problem is in this case, but   
   Linux has two utilities now.   
      
      sudo gdisk /dev/sda  # Identifies whether disk is GPT or MBR   
      
      sudo fdisk /dev/sda  # If MBR, use this utility   
      
   GDisk has an Advanced options thing that offers some useful   
   features. I think one of the features, is clearing the two   
   GPT tables (primary, and the secondary at the end of the disk),   
   so some of the dumber utilities stop thinking a disk is GPT   
   when it isn't.

   Your other thread, refers to materials such as this.   
      
      512n          The original hard drives. Up until recently, a few were still   
   available   
      512e          Most modern drives for consumers are like this. 512 on the   
   outside, 4K on the inside.   
                    The cache is used to hide read-modify-write operations to   
   support 512e.   
      4Kn           Server room 4K logical, 4K physical drives. Up until recently,   
                    these were definitely to be avoided, and Newegg stopped   
   selling these   
                    to consumers (too many returns).   
      
   Then there is this item:   
      
      4Ke           Adapter. Converts some kind of drive, into a  4K logical, 4K   
   physical drive.   
                    An OS which really supports 4Kn, would likely eat the   
   declaration it   
                    is 4Kn and pretend not to know or care there is monkey   
   business going on.   
                    Older OSes, will not like this adapter emulation, any more   
   than they   
                    would like it if you connected a 4Kn to a SATA port.
