Release id #194046 : 1541 Speed Test
Regarding the alignment, would you elaborate your thoughts on the following: (from the docs)
Quote:F3 align the head to track 42 in a better way than other programs do.
F5 moves the head to track 1
How to correctly align a drive:
1) gently unscrew the screws of the track 1 "stop"
2) press F3
3) press F5
4) gently move the track 1 block so there is 0.25 mm (a hair or little more) between the block and the head the head.
5) screw the screws tight carefully checking the block is still at 0.25mm from the head.

A friend who worked 15 years in a commodore repair center told me that.
When a drive is perfectly aligned there must be 0.15-0.25mm between the head and the "block" when the head is in track #1.
Testing my program on real drives reflected this.
If you align the head to track 42 and then move it to track #1 you will see that "hair" space on a correctly aligned drive. |

I don't think zero stop and alignment are the same thing tho... And if you follow Commodore recommendations they state an AAD is required to test the alignment. |

changing the zero stop will... change the track 0 location. it is totally unrelated to the track alignment or even azimuth (yes you need a scope and an alignment disc). oh well >_< |

As the "master of the obvious" just wrote, it was obvious that for "alignment" I intended the track 1 location.
I didn't think it was even needed to be explained in this so "elite" forum.
Even in the commodore service manual is described a similar procedure to correctly set the track stop. |

Regardless of how "elite" the users here are (and rest assured, there's lots of less knowledgeable people here too), you should make sure not to confuse two completely different things such as alignment and track 0 stop/calibration. This can confuse others, or even mislead them. |

This constant mixing up and/or imprecise use of certain terms seems to be a reoccuring problem. Just using the correct terms will help :) |
