Recent tarballs of hdparm include a shell script that you can use 
together with tpctl to do hotswapping of Ultrabay devices on a 600E 
(and almost certainly other Thinkpads).  Basically, the scripts 
included check the output from tpctl -iU every 15 seconds, and if it's 
different from what it was last time, they do "hdparm -U /dev/hdc" 
followed by "hdparm -R /dev/hdc".  This is still considered 
experimental, but it appears to work for some people.  I haven't tried 
it out myself because I only have one Ultrabay device.  HTH,
