The errors while starting BackupMenu are minor! You might in the long run just install libacl1 and libattr1 to get rid of the errors. Yes Photorec is some kind of an application Only for professionals i think. Testdisk is the better in terms of usability of the two. Nevertheless it might be your only chance to use it, because of the weird automatic behavior to create the dot.folders in My Docs, this might just have overwritten the descriptors(pointers) to the files and folders, you had in the folders with the same names before. The 'ot a boot d'-named partition should be your desired 'MyDocs' partition. All kind of problems might get the label or name of a partition to get screwed. You might want to create a clone copy of MyDocs, aka. 'ot a boot d', on your laptop Code: sudo dd=/dev/disk/by-label/'ot a boot d' of=/home/$USER/MyDocs.dd.img bs=4096 Please adapt the path to the partition and to the folder, where you want to store the image, to your needs. You might use Photorec or Testdisk on the image as well and could just reformat the MyDocs partition and carry on.
