exportation impossible W10

[jacques]

Bonjour, Lightroom classique 11-3-1. W10. Impossible d'exporter. Message d'erreur:
Impossible d'enregistrer le fichier.(1) Le nom du fichier suit.
J'ai essayé plusieurs formats, tiff, jpeg, avec des tailles différentes : 22Ko 400 Ko 1 Mo 150Mo. J'ai désinstallé Lightroom plusieurs fois, revu les paramètres, rien n'y fait. En ce moment je travaille tous les jours sur des fichiers Tiff, et c'est mon premier problème, c'est arrivé il y a trois jours. Merci pour une solution si vous l'avez.

Is the original photo available to LrC at time of export, or is it missing?

Hello, Problems solved. By dint of searching and searching with the advice of everyone, I ended up realizing that the partition where I intended my Tiff files presented a problem, which I had not realized, this disk until present worked perfectly; I thought of many configuration problems, except for a hardware problem. Formatting this drive had no effect. So disk changed, everything is back to normal. In fact Lightroom, had nothing to do with this story. Thank you all.
