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.
