It means the same as the flashing light on the front of most PCs. The
drive is in use. If you remove it when the light is on you may lose or
corrupt data. The whole purpose of the light is to tell you that there
the memory is being written to or read from.
I cannot believe that. It is now 15 minutes since I pressed eject and
the light is still flashing. Unless, of course, eject is not the same as
unmount.

Try this sequence ( the device in this case is /dev/sda1 )

$ pumount /dev/sda1

Comment: OK, no errors so it is unmounted now...

peter@prospero:~ $ pmount /dev/sda1

Comment: No errors, so now it's mounted again.

So, with the "stick" still plugged in, the system still "knows" it is
there after the "pumount" command , but ...

peter@prospero:~ $ eject /dev/sda1
peter@prospero:~ $ pmount /dev/sda1
Error: device /dev/sda1 does not exist

... after "eject", the system has total amnesia about it ;-)

That's a /highly technical explanation/ of the difference, I know *grin*

So the "eject" command is better than the (p)umount cause it goes
farther by completely remove the device from the system.
The light being still running is just, on some cases, because the stick
is still pluged in and by the mean still electrically alimented.
See, there are different sort of Stick (I would like to point out the
light system). On some of them there is 2 LED of different color (even
though the key seems to have just one light point) . One for the
alimentation and the other for signaling the access on the stick. Other
sticks just have the light of access.


I believe Scott is speaking about the second one. So with his stick,
having the LED on means something is accessing the Stick.
But Norman' Stick got the alimentation light so it will never turn off.
