Disk Flags:

Information: You may need to update /etc/fstab.
■「/etc/fstab」からsdbをコメントアウトしないといけないようだ。
$ sudo grep sdb /etc/fstab
$ sudo parted /dev/sdb mklabel gpt
Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue?
Yes/No? Yes
Information: You may need to update /etc/fstab.
■「/etc/fstab」からsdbをコメントアウトを解除してフォーマット
$ sudo grep sdb /etc/fstab
/dev/sdb1 /media/usb0 auto rw,user,noauto 0 0
$ sudo parted /dev/sdb "mkpart primary ext4 65535s 100%"
Warning: You requested a partition from 33.6MB to 3001GB (sectors 65535..5860533167).
The closest location we can manage is 3001GB to 3001GB (sectors 5860532224..5860533134).
Is this still acceptable to you?
Yes/No? Yes
Information: You may need to update /etc/fstab.
