기존 파티션을 삭제하고 새로 파티션 생성

orangepi@orangepi3b:~$ sudo fdisk /dev/mmcblk1
 
Welcome to fdisk (util-linux 2.37.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
 
GPT PMBR size mismatch (122879999 != 124735487) will be corrected by write.
This disk is currently in use - repartitioning is probably a bad idea.
It's recommended to umount all file systems, and swapoff all swap
partitions on this disk.

Created a new partition 2 of type 'Linux filesystem' and of size 58.4 GiB.
Partition #2 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.
Syncing disks.
