我正在将 SanDisk 32 GB SD 卡格式化为 NTFS。这花了很长时间，所以我中途停止了。现在我的 SD 卡不再被检测为外部设备，无论是在 Linux 还是在 Windows 中。
但/var/log/messages在Linux中插入时会识别设备：
sudo tail -f /var/log/messages

Gparted 也可以看到该设备：
但是所有 fdisk、gparted 和任何其他磁盘管理器软件都无法创建新的分区表或分区，甚至无法格式化它。
我收到的错误信息是
“访问 /dev/sdb 时出现 I/O 错误”
如果您需要我运行命令来查看其输出，只需在评论部分提及它。
