How to mount a USB flash drive in Linux, how to mount a USB flash drive in virtual machines, and how to mount a USB flash drive in Ubuntu

Step 1: view the USB flash disk Information
First, run the sudo fdisk-l command to check where the USB flash disk is located, that is, where the USB disk is mounted.

(If the fdisk-l command is used directly without any results, you must add sudo to run it as an administrator)

After viewing this information, you may see the following information:

Disk/dev/SDA: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 Cylinders

Partition 1 has different physical/logical beginnings (non-Linux ?) :
Phys = (0, 2, 0) logical = (0, 2, 27)

From the last few lines, we can see that the U disk is mounted under/dev/sdc1. Remember this mount point, which varies according to the Linux system.

Step 2: mount the USB flash drive to the specified Node
We mounted the U disk to the/mnt/USB directory (we can see that it is a USB flash drive in FAT32 format)
# Mount-T vfat/dev/sdc1/mnt/USB
If it is an ntfs u disk, it is similar to the following:
# Sudo Mount-T ntfs-3g/dev/sdc1/mnt/USB
/Mnt/USB: Specify the node you want to attach.

Then you can access the USB flash disk through CD/mnt/USB.

Step 3: unmount the USB flash drive
Run the following command: # sudo umount/mnt/USB flash drive is uninstalled (Note: you cannot enter the preceding command in the/mnt/USB directory, otherwise, the system will think that your "device is busy" and refuse to detach the USB flash drive ).
