No Partition found

#1 Post by Hartmut » 01 Mar 2016, 10:40

Hallo,

mein USB Stick (4 GB) reagiert leider nicht mehr, auf dem sich mehrere Wochen intensiver Arbeit befinden.

Mit Testdisk bekomme ich untenstehenden Output. Search and Deep search liefern nichts (erst Meldung: kein endmark, dann nichts). Dann habe ich None als Format gewählt, und unter Advanced RebuildBS probiert, mit dem Ergebnis "Can't find cluster size". Das war nicht erfolgreich egal mit welchem Typ (Fat32, etc.).
Ansonsten bekomme ich im Log auch den Hinweis auf einen E/A Fehler. Ansonsten habe ich unzählige Datenrettungsprogramme drüber laufen lassen, aber alle finden nichts.

Ist der Stick hinüber und die Daten verloren? Angesichts des Verlusts würde ich gerne noch mehr versuchen.
