Manually Mount a USB Drive

A USB storage device plugged into the system usually mounts automatically, but if for some reasons it doesn't automount, it's possible to manually mount it with these steps.

    Press Ctrl+Alt+T to run Terminal.
    Enter

Code:

sudo mkdir /media/usb

to create a mount point called usb.
    Enter

Code:

sudo fdisk -l

to look for the USB drive already plugged in, let's say the drive you want to mount is /dev/sdb1.

    To mount a USB drive formatted with FAT16 or FAT32 system, enter:

Code:

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

    OR, To mount a USB drive formatted with NTFS system, enter:

Code:

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

To unmount it, just enter sudo umount /media/usb in the Terminal.
