I discovered       this in one of the non-copied versions when the wright gate control on a       floppy drive failed. The system reported the wrights to be verified but       when the disk was removed & tried in a different drive nothing had       changed. That failure has only been around for a few decades but as       long as the hardware is so reliable why waste time fixing something       rarely complained about. Most techs today just change out hardware or       re-install the software anyway. Very few could diagnose the failure of       a single 50 cent chip as the cause of a system failure.              JamesSoCal              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
