Solution:1

Maybe you could try manually unmounting the usb drive from the terminal.

Identify

First you will need to know the mount point or the device. You have a few options but in your case I think the first will tell you what you need to know.

1.To see information about currently mounted systems, simply run:

mount  

2.To see a list of your USB devices (the vendor and device ID's), run:

lsusb  

3.To see all attached storage devices and their partitions, run:

sudo fdisk -l  

Unmounting

Unmounting is done through the "umount" command, which can be given a device or a mount point

sudo umount /dev/sdb1  

or:

sudo umount /media/external  

Would both unmount the filesystem on /dev/sdb1 if it is mounted on /media/external.

Remember that a filesystem cannot be in use when it is unmounted, otherwise umount will give an error. If you know it is safe to unmount a filesystem you can use:

sudo umount -l /mountpoint  

To do a "lazy" unmount
