分区已成为写保护？

我无法写入特定分区，该分区为 FAT 格式。经过一番搜索，我运行了以下命令：

fdisk -l

我得到的输出是（循环设备已删除）：

Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes

Partition 3 does not start on physical sector boundary.
Partition table entries are not in disk order.

我还运行了另一条命令，

gdisk -l /dev/sda

输出如下：

GPT fdisk (gdisk) version 1.0.1

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: not present

请帮忙。不知道该怎么办。
