in meinem alten Laptop hatte ich eine SSD die ich jetzt gerne an meinem RASPI verwenden möchte. Leider erinnere ich mich an das ATA/Festplattenpasswort nicht mehr. Gibt es eine Möglichkeit die Festplatte zurückzusetzen, sodass sie wieder nutzbar wird? Die Daten darauf können dabei ruhig verloren gehen.
Folgende Infos konnte ich der SSD mit HDPARM (angeschlossen an den raspi über ein usb-ssd gehäuse) entlocken:
