USB storage devices
This document describes how to use the popular USB memory sticks with Linux. However, it is also valid for other devices such as digital cameras that act as if they were just a USB storage device.
If you have an up-to-date system with the standard Arch kernel and a modern Desktop environment your device should just show up on your desktop, with no need to open a console.
Auto-mounting with udisks
Getting a kernel that supports usb_storage
If you do not use a custom-made kernel, you are ready to go, for all Arch Linux stock kernels are properly configured. If you do use a custom-made kernel, ensure it is compiled with SCSI-Support, SCSI-Disk-Support and usb_storage. If you use the latest udev, you may just plug your device in and the system will automatically load all necessary kernel modules.
The first thing one needs to access a storage device is its identifier assigned by kernel. See fstab#Identifying filesystems for details.
Mounting USB memory
You need to create the directory in which you are going to mount the device:
# mkdir /mnt/usbstick
Mount the device as root with this command (do not forget to replace device_node by the path you found):
# mount device_node /mnt/usbstick
# mount -U UUID /mnt/usbstick
mount does not recognize the format of the device you can try to use the
-t argument, see
man mount for details.
As normal user with mount
If you want non-root users to be able to write to the USB stick, you can issue the following command:
# mount -o gid=users,fmask=113,dmask=002 /dev/sda1 /mnt/usbstick
As normal user with fstab
See Fstab#Writing to FAT32 as Normal User if you want normal user to do the mount/unmount action.
