1、查看盘符
查看U盘对应的盘符: df -h
kylin@kylin:~/Download/deb包/ventoy-1.0.11$ df -h 文件系统 容量 已用 可用 已用% 挂载点 udev 3.9G 0 3.9G 0% /dev tmpfs 785M 3.4M 782M 1% /run ... ... ... ... ... /dev/sdb6 146G 63G 77G 46% /home tmpfs 785M 48K 785M 1% /run/user/1000 /dev/sdc1 58G 32K 58G 1% /media/kylin/ven
2、卸载U盘:
我的U盘盘符为dev/sdc1(不确定的话,可以使用命令对比下插入前后的区别),先卸载U盘
kylin@kylin:~/Download/deb包/ventoy-1.0.11$ sudo umount /media/kylin/ven
3、修复U盘:
使用命令进行修复: sudo dosfsck -v -a 对应路径
kylin@kylin:~/Download/deb包/ventoy-1.0.11$ sudo dosfsck -v -a /dev/sdc1 fsck.fat 4.1 (2017-01-24) Checking we can access the last sector of the filesystem Boot sector contents: System ID "mkfs.fat" Media byte 0xf8 (hard disk) 512 bytes per logical sector 32768 bytes per cluster 64 reserved sectors First FAT starts at byte 32768 (sector 64) 2 FATs, 32 bit entries 7569408 bytes per FAT (= 14784 sectors) Root directory start at cluster 2 (arbitrary size) Data area starts at byte 15171584 (sector 29632) 1886688 data clusters (61822992384 bytes) 32 sectors/track, 64 heads 2048 hidden sectors 120777716 sectors total Reclaiming unconnected clusters.

之后就可以使用了,大功告成!
