问题：
ubuntu18.04系统重启后识别不到移动硬盘，机器重启前可以正常挂在移动硬盘。

排错：

1. 重新安装exFAT格式支持包

sudo update
sudo apt install exfat-fuse exfat-utils

2. 重新拔插硬盘

查找原因：可能是在apt upgrade过程中强制中断导致内核模块部分缺失

ls /lib/modules/$(uname -r)/kernel/drivers/usb/storage/usb-storage.ko		# 验证模块是否存在
sudo apt install --reinstall linux-modules-extra-$(uname -r)		# 重新生成内核模块
sudo depmod -a

2.2 修复内核版本一致性‌

若内核版本不匹配，需重启至正确内核或更新系统：

sudo apt update && sudo apt upgrade
sudo reboot

2.3 手动安装驱动模块（紧急情况）‌

从官方仓库下载对应内核版本的 linux-modules 包并解压到 /lib/modules 7：

sudo apt download linux-modules-5.15.0-46-generic
dpkg -x linux-modules-*.deb /tmp/modules
sudo cp -r /tmp/modules/lib/modules/* /lib/modules/
