When doing "# grub2-mkconfig -o /boot/grub2/grub.cfg"

I get some "errors":
Generating grub configuration file ...

ERROR: unsupported sector size 4096 on /dev/sdg.
ERROR: unsupported sector size 4096 on /dev/sdg.
ERROR: unsupported sector size 4096 on /dev/sdg.

There is NO partitions in /dev/sdg:
# fdisk -l /dev/sdg
Disk /dev/sdg: 2.7 TiB, 3000558944256 bytes, 732558336 sectors
Units: sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

# lsscsi | grep /dev/sdg
[8:0:0:0]    disk    WD       My Book 1230     1065  /dev/sdg 

Anyhow, grub/grub2-mkconfig is working flawlessly.
And it has been happening forever with that device(WD My Book)
So, for me is not an error. But grub2-mkconfig complains loudly.
