That reminds me of my "problem" discussed in the thread: "after sidux upgrade: "Can not access device" with 1 of 4 luks partitions" To 99% I did write the data off, because fortunately not vital data. But hope dies last. Anyway I still had no time and energy to try such a restoration of my "lost" LUKS partition. Also because the official LUKS website http://luks.endorphin.org/ is still offline. Does anyone have any information about this? So I guess thers's lack of expert knowledge on how to do this attempt of restoration. regards Orinoco
