IBM sent me the following file which is a similar noise but apparently
a slightly different drive.  


To experience "the real thing" crank up the volume
until you can hear the sound 8 feet away and then sit down 1 foot from
the speaker and play it again.  Once every 30 seconds. 

I'll keep this file on my site for a month or so.
