外部硬盘不允许写ext4 / fat32太小？

我已经格式化（使用GParted）外部硬盘驱动器以供使用，因为它是NTFS，但是写入权限被拒绝，然后我尝试了fat32，但是文件大小太小，没有exfat选项，并且我想使用密码保护插入等时可能

如果可能的话，如何获得驱动器以允许我写入并输入密码？我的ext4程序有什么问题？主要扩展名为ext4的外部硬盘，可以看到，安装和打开但不能写吗？

我刚刚使用下面的命令尝试过，但也没有用。

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.

它说w是一个无效的参数，那么我该怎么办，exfat分区的此选项在Linux mint上不可用吗？还是命令已更改？

现在，此问题已与以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.

我现在输入的是从一个网站。

（显然exfat适合在多个系统上使用，因此首选，ntfs已在gparted上，首选ext4是首选），除非我不知道exfat有其他问题？还是在Linux中不可行？
