Get the Information

Sometimes devices don't automount, in which case you should try to manually mount it. First, you must know what device we are dealing with and what filesystem it is formatted with. Most flash drives are FAT16 or FAT32 and most external hard disks are NTFS.

sudo fdisk -l

Find your device in the list, it is probably something like /dev/sdb1.

Now we need to create a mount point for the device, let's say we want to call it "external". You can call it whatever you want, just please don't use spaces in the name or it gets a little more complicated - use an underscore to separate words (like "my_external"). Create the mount point:

sudo mkdir /media/external

Mount the Drive

IconsPage/example.png We can now mount the drive. Let's say the device is /dev/sdb1, the filesystem is FAT16 or FAT32 (like it is for most USB flash drives), and we want to mount it at /media/external (having already created the mount point):

sudo mount -t vfat /dev/sdb1 /media/external -o uid=1000,gid=100,utf8,dmask=027,fmask=137

The options following the "-o" allow your user to have ownership of the drive, and the masks allow for extra security for file system permissions. If you don't use those extra options you may not be able to read and write the drive with your regular username.

Otherwise if the device is formatted with NTFS, run:

sudo mount -t ntfs-3g /dev/sdb1 /media/external

Unmounting the Drive

IconsPage/example.png When you are finished with the device, don't forget to unmount the drive before disconnecting it. Assuming /dev/sdb1 mounted at /media/external, you can either unmount using the device or the mount point:

sudo umount /dev/sdb1

or:

sudo umount /media/external
