Trick with USB drives

[Matt Patterson]

I don't know if anyone has ever had this, but...If you have for example 
a usb stick drive plugged in and mounted, but you forget and unplug it, 
then sometimes you can't unmount it. You definitely can't unmount it 
unless you plug the stick back in. The trick is to use the mknod command 
to create in the /dev/ directory a node identical to the one that was 
there when the device was connected, then unmount the drive. Then you 
can delete the node you created.

I have a flky usb card so I have this a lot, this is the best solution I 
have found.
