Can you Right Click and then select "eject"?

If not, find out what device it is while its mounted, and then:
1.  right click and select safely remove, and go to a shell and see if the 
device is still mounted.  If its not, you can remove it.  If it is go to next 
2.  Run:  "sudo umount /dev/sdax" (x being whatever device you are wanting to 
remove).  Check to see if the device is still mounted.  If you could unmount 
it using root's account (sudo part) chances are your stuff is getting mounted 
as root for some reason.

Once you make sure the device isn't mounted, even if the drive light is on, 
you're safe.  If the devices are not mounted, they are not in use.

I know this because my external WesternDigital USB drive stays lit up even 
after I safely remove.  After numerous checks I found that in truth the 
volumes were not mounted, and I could remove it.
