Festplatte mit 0 Bytes - Unsupported sector size 520
Ich hatte SAS Server Festplatten auf Ebay gekauft, diese hatten eine Sector Größe von 520 statt 512, damit konnte mein Linux Server nicht arbeiten.

sg_format /dev/disk/by-id/scsi-SSEAGATE_ST910006CLAR1000_9XG86B5W_0000C526KTTB -v --format --size=512Ich habe hier lieber by-id genutzt, da ich mir nicht sicher bin, wie gut sdb da funktioniert hätte und ich eh die Seriennummer auf der Festplatte lesen kann.
Je nach Größe dauert das schon seine paar Stunden, er fragt anfangs noch ein paar mal, ob die Festplatte wirklich gelöscht werden soll.
Wenn man nichts macht, führt er es einfach aus.
Am Ende kommt dann sowas:
