Try these:

pumount /dev/sda1

then there's 

eject /dev/sda1

Also, you might get better info by running  dmesg | tail after plugging t
he device in (it should tell you the device - for instance "sda" )

There is a way to "force" a umount but it's kind of messy

umount -l   (so called lazy umount)

In general for USB storage devices you would use pmount/ pumount
