Not so, servo tracks have position information encoded within them - the drive knows when it is at the correct servo track --- Paul Sanderson Sanderson Forensics -----Original Message-----
If you *write* the servo signal and you're off by 0.0020" one way, and then the next time you go to find the track, you're off by 0.0020" the *other* way, then the servo track is 0.0015" out of range - and you can't find the track anymore. Even worse, if the next track over is *also* out-of-spec, you can end up accidentally aquiring the servo signal for the *wrong* track. Whoops. ;)
