It would be great if between us we could write up a proper solution. I 
have exams for the next month or so, but after that I might get back 
into this a bit.

I know nothing about HAL/udev or whatever other dynamic device managers, 
but it should be possible to put it into one of those surely. KDE and 
gnome have options for ejecting USB devices now, so it must be possible 
to tell them how to eject an ultrabay device and put it into the same 
system like it is in Windows.

Here's my current script anyway. ub is the main script I run to 
eject/insert. I use kdialog for errors because I run it from alt+f2 in 
KDE. ubject is a sudo'd script to power off the device. I also added an 
option to flash the LED so I knew it had succeeded. I think the idea was 
I would use that to provide output instead of kdialog and hook it into 
the ACPI events, but I didn't get round to it.

Apologies for it being truly horrible code. This was written a long time 
ago, before I did any real coding. You should see my 'fixsound' and 
'wifi' scripts! I really should learn to do these things properly lol.

Hope this is of some use. Please do whatever you like with it. It works 
for me at least. You'll need the debian-hotswap package though.
