本文详细介绍了如何在Linux系统中挂载和卸载USB驱动器。包括插上U盘后的内核消息查看、获取文件系统类型、创建挂载目标目录、挂载文件系统及最后的卸载步骤。特别指出，在卸载过程中要确保设备不处于使用状态，否则可能需要强制或懒惰卸载。

[Mount]
1. Plug in your thumb drive.

2. Print out the kernel messages. Your thumb drive will appear as something similar to /dev/sdb (check with the vendor name and model number):

$ dmesg

3. Obtain the file system. It should be something similar to /dev/sdb1:

$ fdisk -l

4. Create a target directory where you want to attach to:

$ mkdir /mnt/usb

5. Mount the file system to the directory that you created. Now your thumb drive is accessible on /mnt/usb:

$ mount /dev/sdb1 /mnt/usb

[Unmount]
1. Unmount by specifying the directory path where it has been mounted:
$ umount /mnt/usb

* Note that the thumb drive should not be busy. In case you cannot wait to properly unmount a device, you can forcefully or lazily unmount it:
$ umount -f /mnt/usb
or
$ umount -l /mnt/usb
