It looks like I can't change logical size to 4096.

sudo ./SeaChest_Lite -d /dev/sdc --showSupportedFormats

This disk used to be in USB adapter case but recently I had problems because it didn't work with USB3 port, so I removed it from case and after that when I attached it through Sata cable I had it recognized as PTTYPE="PMBR". I want to avoid such problems in the future.
Code:
TestDisk 7.1, Data Recovery Utility,
Disk /dev/sdc - 3000 GB / 2794 GiB - CHS 357698 64 32 Current partition structure: Partition Start End Size in sectors

but sgdisk (I don't remember how it was connected then) showed logical/physical): 4096/4096 bytes.
sudo fdisk -l

Partition 1 doesn't start on the boarder of physical sector..
sgdisk -p /dev/sdc

Partition table holds up to 128 entries Main partition table begins at sector 2 and ends at sector 5 First usable sector is 6, last usable sector is 732566639 Partitions will be aligned on 8-sector boundaries Total free space is 2640 sectors (10.3 MiB)

I updated firmware but
Code:
hdparm -I /dev/sdX | grep 'Sector size:'
still shows that only 512 Logical Sector size is supported. So, I am confused why sgdisk showed 4096/4096.
I want to format it with GPT and one partition only.
Forcing change of logical sector size to 4096 is not a good idea, is it?
I read something about Advanced Format and that it is better and about SmartAlign™ Technology for Advanced Format Hard Drives.
How should I proceed? Should I force change? I will not use USB adapter any more.
