Well, that's quite a different story, isn't it?

I was (and still am) more like thinking aloud and I haven't checked  
what you get without the disk being inserted but I tend to believe  
that even with a disk in the drive you may get a (fairly - for this  
purpose) decent seed as no discs are identical, identically inserted,  
rotating with identical speed, spun-up at the very same time and read- 
out in the very same moment... Combine it with the timers drift and  
you may get "close enough" to a random.

Neither do I ;-)
