传输过程中电脑关闭后，microSD 卡可能会损坏，无法自动安装

当我插入 microSD 卡时，它不再自动挂载。我可以通过 sudo 手动挂载它并重新格式化它，但它仍然显示在 fstab 中：

Device     Boot Start       End   Sectors   Size Id Type
/dev/sdb1        2048 250085375 250083328 119.3G  b W95 FAT32

当我跑步时dmesg我得到

有什么办法可以修复该卡吗，或者它已经坏了？

答案1

从 dmesg 看来似乎无法读取分区表，所以让我们重新创建它。// 是注释，而不是命令的一部分

sudo fdisk /dev/sdb //Here you're using fdisk utility on /dev/sdb disk 
d //d stands for delete partition
g //g is for recreating GPT table
n //n stands for new
p //p stands for primary partition
ENTER //Press enter key
ENTER
ENTER
w //w means write changes on disk
sudo mkfs.ext -F 32 -I /dev/sdb1 //Command that formats the partition you created in EXT32, must be run outside fdisk

之后，如果您想将其添加到 fstab 中，首先获取新的 UUID：sudo blkid /dev/sdb1

并在 /etc/fstab 中添加如下条目：

UUID=(UUID) /folder/where/to/automount vfat defaults 0 0
