Safely remove USB drive from command line

Open a terminal window and run (replace sdc with the appropriate device):

udisks --unmount /dev/sdc1 && udisks --detach /dev/sdc

You can find the device name using the mount point (replace MOUNT_POINT with the appropriate mount point, eg, /media/disk):

grep MOUNT_POINT /etc/mtab

  1. It's very odd that Thunar doesn't implement this function (as far as I know). When I used to work with Thunar, I removed USB drive through Nautilus, to be sure that data on it wouldn't be damaged. This issue and absence of tabs in Thunar forced me to use Nautilus in Xubuntu.

    BTW, thanks for this great blog!

    1. You're very welcome :)

      Safely USB drive removal is another reason to install Nautilus in Xubuntu, but is nice to have a alternative.
