Your hard drive has a physical sector size. If that physical sector size is 4096 than you should format your drive with the same sector size. Generally speaking
gparted should recognize this and format your drive in the sectorsize and alignment that your drive needs. Since several years manufacturers are using 4096 as physical sector size and emulate 512 bytes. 512 bytes was the old standard and 4096 is the new one. They went from 512 to 4096 because of the increasing capacities of the hard drives.
You could rund
Your output could look like this:
Disk /dev/sda: 119,2 GiB, 128035676160 bytes, 250069680 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xa4b57300
In this case the hard drive has 120 GB of space and a physical sector size of 512 bytes.
