No probem any more. I thought I have seen track 1 unreadable yesterday, but I cannot reproduce.
But I have one other problem with nibread / nibwrite:
I have installed Bitte melde dich an, um diesen Link zu sehen. to work with my zoomfloppy.
Then I updated nibtools with Bitte melde dich an, um diesen Link zu sehen. .
Result:
nibread from root.org image works[*][**], updated nibread fails[***]. For nibwrite it is the opposite - the new one is working better than the old one.
[*] of cause this old version needs "-s".
[**] Rarely it fails, too. But that is Rarely. Repeating the job helps in that cases.
[***] at least for nb2. nib sometimes work.
Output is below - I'm adding english translation for german messages in angle brackets:
