Lets look at it another way... If the drive is still working now, rather, if I have a Disk ][ Drive here, thats like serial # 38 or something, which I do, and after all these years it's still working. The recalibration is nary a worry. FWIW, even those drives that are 'quiet', are still wracking up against the end of their stroke. tdiaz (a) apple2(dot goes here) org
