How to change dos to ext4 on a hdd?
Hello guys,I try to format a hdd, but it keeps saying that I got a dos-partion on it.
My attempt below, what do you think guys is it possible?
pi@raspberrypi-NAS:~ $ sudo fdisk /dev/sda
Welcome to fdisk (util-linux 2.33.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p):
Using default response p.
Partition number (1-4, default 1):
First sector (2048-625142447, default 2048):
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-625142447, default 625142447):
Created a new partition 1 of type 'Linux' and of size 298.1 GiB.
Partition #1 contains a ext4 signature.
Do you want to remove the signature? [Y]es/[N]o: Y
The signature will be removed by a write command.
Command (m for help): w
The partition table has been altered.
