Giriş
Açıklaması şöyle.

Conversely, if you use fdisk (or any other partitioning tool) to create a new partition table, the tool will overwrite the first few bytes of the disk to store that new table

Welcome to fdisk (util-linux 2.29.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
