What do I need to do to mount a USB drive in ArchLinux

Solution 1:

mount /dev/sdXY /path/to/location/of/your/choice

Where XY is the sticks device node and partition (e.g. /dev/sdb1)

Solution 2:

Simply run fdisk -l to see what your USB device is called. Then make a directory - mkdir /mnt/my_usb - and mount it there: mount /dev/sdXY /mnt/my_usb.
