我已经格式化（使用GParted）一个外部HDD，因为它是NTFS，但是写入权限被拒绝，然后我尝试了fat32，但文件太小，没有exfat选项，我想要一个密码保护如果插入等时可能。
如果可能的话，我怎样才能让驱动器允许我写入并拥有密码？我的 ext4 进程有什么问题？主扩展 ext4 外置硬盘，全部可见，已安装且可打开但不可写？
我刚刚使用下面的命令尝试过这个，它也没有工作。

Welcome to fdisk (util-linux 2.31.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

The kernel still uses the old partitions. The new table will be used at the next reboot.

它说 w 是一个无效的参数，那么我该怎么办，这个 exfat 分区选项在 linux mint 上是否不可用？还是命令变了？
现在这个问题与之前使用的命令一起列出 =
$ sudo wipefs -a /dev/sdb1
wipefs: /dev/sdb1: ignoring nested "dos" partition table on non-whole disk device
wipefs: Use the --force option to force erase.
我现在输入的内容来自一个网站。
（exfat 显然适合在多个系统上使用，因此是首选，ntfs 已经在 gparted 上，ext4 是最后一个选项）除非我不知道 exfat 的其他问题？或者这在linux中不可行？
