Gparted shows First sector: 8192, Last sector: 15704063,
Total sectors: 15695872.
8 x 10^9 bytes / 1.6 x 10^7 sectors
~= 8/16 x 10^3 bytes/sector
~= 512 bytes/sector.
A familiar old number.
Gparted also shows 4.00 MiB unallocated bytes at the front of the
device.
If gparted simply does "Partition > Format to > ext2", is there any
chance it will change alignment or block size?
Otherwise, how should the new file system set up without damaging
those crucial parameters?
