Maybe (just maybe) the problem is in your 12 VDC power supply. This is the supply that powers the drives motors (floppies included). If the supply is marginal as in filtering/regulating problems or if it is overheating from too much load (too many drives) the symptoms that you described could quite possibly appear. The shutdown you describe would tell me to look at a regulator as these devices have built in thermal shutdown devices. It's just too coincedental that *both* drives are dead. I have a Quantum 40Q hard drive that wouldn't spin up occasionally due to Power Supply problems, but the disk drives worked fine. The fix... A bigger power supply. Hope this saves you a couple of bucks :-) I hear tell that a 200W I*M supply will work as the voltages required are the same: +5 -12 +12 . But that's just what I heard. -- -------------------------------------------------//------------------------- (ames att sun)!pacbell! ----> sactoh0!pacengr!americ!erk Multitasking, ucbvax!ucdavis!csusac! --/ // Never leave uunet!msac! -/ Erick Parsons \Sacramento Ca Home Without it --------------------------------------------\X/----------------------------- Please Don't Wait...
