-Plug in the USB Stick and identify the corresponding block device (''/dev/sdX'') using lsblk. 
  
-Example output for ''lsblk'': 
-<code> 
-$ lsblk 
-NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT 
-sda           8:   0   2.7T  0 disk  
-└─sda1        8:1    0   2.7T  0 part /mnt/hdd 
-sdb           8:16     3.8G  0 disk

-A quick guide to reading the output: 
-''lsblk'' uses a tree to show devices and their partitions. For example ''sda1'' is the first partition on ''sda'' and ''nvme1n1p1'' is the first partition of ''nvme1n1''. 
- 
-''sdX'' where ''X'' is a small letter starting from ''a'' usually represents a SATA or USB drive, names starting with ''nvme'' represent NVME SSDs and SD cards usually start with ''mmcblk''. 
-These names represent the device as found in ''/dev'', so ''sda'' is found under ''/dev/sda''.
