Re: Failed 5.25" Disk Drives

  I was thinking the same thing.  I was wondering if those bad drives
somehow blow the controller chip on the drives.  I have had some DISK
][ drives do this to me.  I remeber buying a new chip at a local
electronics store (no longer open.. :( ) and all was good.   I have
never took a Unidisk 5.25 apart (I perfer the DISK ][ as well) but I
would asume that it's the same thing...  :/
