# Storage Device Management
In order to interact with a USB device on a Linux system it first has to be
`mounted`. In order to mount a USB device, one must first identify the device
name, and then use the `mount` command.
## Finding a Storage Device Name
USB devices are assigned names when they are connected to a Linux operating
system. The first storage device is assigned the name `sda` (storage device a),
the second `sdb`, the third `sdc` and so on.
One may use the `lsblk` to list the detected storage devices for a system, which
will output something like this:
```
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 1 50G 0 disk
├─xvda1 202:1 1 200M 0 part
├─xvda2 202:2 1 2M 0 part
└─xvda3 202:3 1 49.8G 0 part /
xvdb 202:16 1 1.9T 0 disk /rw
xvdc 202:32 1 10G 0 disk
├─xvdc1 202:33 1 1G 0 part [SWAP]
└─xvdc3 202:35 1 9G 0 part
xvdd 202:48 1 526.8M 1 disk
```
Then after plugging in the Storage Device run `lsblk` and look for what's
different. In this example, the newly detected storage device is `sdb`:
```
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdb 8:16 1 14.5G 0 disk
xvda 202:0 1 50G 0 disk
├─xvda1 202:1 1 200M 0 part
├─xvda2 202:2 1 2M 0 part
└─xvda3 202:3 1 49.8G 0 part /
xvdb 202:16 1 1.9T 0 disk /rw
xvdc 202:32 1 10G 0 disk
├─xvdc1 202:33 1 1G 0 part [SWAP]
└─xvdc3 202:35 1 9G 0 part
xvdd 202:48 1 526.8M 1 disk
```
## Mounting a Storage Device
In order to mount a device, first ensure that the directory you will mount to
exists by running:
```sh
mkdir -p /media/usb
```
Then run the following command to mount the storage device:
```sh
sudo mount /dev/<usb_device_name> /media/usb
