So, please post the reparse tag for this file algemeen.txt : getfattr -h -e hex -n system.ntfs_reparse_data somepath/algemeen.txt Also please post the contents of file 1545290. I do not know its name, but it must be in the Stream directory, with a suffix .ccc. To get its name do : ls -li *as*usual*/Stream/*.ccc | grep 1545290 > > # ntfsinfo -fvi 0 /dev/mapper/lvm1--vol-sr7--disk2--snapshot--copy2 > http://paste.debian.net/plainh/486b1a01 So inode 1582022 must be in cluster 30826611 and inode 1545290 in cluster 30817428. Please post the outputs of : dd if=/dev/mapper/lvm1--vol* skip=30826611 bs=4096 count=1 | od -t x1 dd if=/dev/mapper/lvm1--vol* skip=30817428 bs=4096 count=1 | od -t x1 The sequencing error which had been detected may have disappeared with no evidence left, but it is worth trying. > I feel we may be almost there (support for data deduplication), but > still hitting a few unreadable files... I hope so, this is an uneasy situation for me, as I cannot reproduce the errors. Thanks for you cooperation to the bug hunt.
