   I have a USB hard disk enclosure, and I'm running it without it's case as I'm   
   testing another drive with it.  When I touched the hard disk with my hand and   
   the case of the computer (which is earthed) with my arm, I felt a tickle.  So   
   I connected a    
   multimeter to it, and the hard disk is at 90 volts AC with a short circuit   
   current of 0.136 mA.  Is this normal?  Is this a good idea when working with   
   delicate computer electronics?  I suppose the ground of the USB lead will get   
   rid of it but it seems a    
   bit odd.  The USB disk unit is powered by a cheap wall wart that came with it,   
   rated 12V DC 1.5A.
