   I'm not 'forgeting' that, since the message I was responding to   
   said 'magnetic field disturbances'.   
      
   In any case, your idea is also bullshit.  Neutrinos in space will be   
   utterly insignificant unless you're operating your hard drive   
   right next to a supernova (in which case neutrino damage will be   
   the least of your problems).  As for gamma radiation doesn't damage   
   mangetic disks.  It might affect the semiconductors in the drive   
   controller, but magnetic materials are highly radiation resistant.   
      
   Just what is this big source of gamma radiation you're worrying   
   about, btw?  Cosmic radiation doses are mostly from charged particles.
