En gros le format pasti et sa lib est un emulateur de WD1772 et non pas de disquette. Il faut donc reconstruire a partir des timing WD1772 une track physique.
Il avait comme projet de faire une lib d'abstraction pour faciliter cette tache. Je vais le recontacter pour savoir a quelle stade en est cette librairie (sans trop d'illusion). Sinon je vais tenté de recupérer le nécéssaire pour utiliser sa lib et faire ma propre couche d'abstraction pour convertir les fichiers pasti en un format plus classique.
