    Default Realigning a 1541-II drive (Commodore 64)

    The inevitable happened, drive did a good ol series of WHACKACKACKACKACKACKA against the track zero stop and now its misaligned and won't read squat. I've seen a few howtos on realigning the classic 1541, but nothing on the 1541-II drives. Any suggestions or help on how to realign the heads?

    Thanks!

    The reason there are no docs for it is because it shouldn't be possible for it to go out of alignment. I thought that all 1541-II's had optic track 0 sensors and didn't bang the heads... Possible the sensor is malfunctioning if you got head bang.

    It's more likely something actually broke, unfortunately.

    The 1541Cs and 1571s have optical track 0 sensors. According to documents I have found, "The support for the optical "track 0" sensor, which was introduced in the 1541C firmware, was removed in the 1541-II firmware".

    Also the 1541-II machineguns when attempting to reset to track 0. That's a dead giveaway.

    Quick dumb question: Have you initialized the drive?

    I'm nibtooling a bunch of disks right now, and every once in a while nibread's head bump routine knocks my drive out until I send the initialize command.
