Re: endless loop in libntfs!!!
Here's the requested data, from the corrupted image.
This is wrong, it is a fragment of the journal. I however see no error in the command I posted :
dd if=BACKUP of=mft.copy bs=4096 skip=786432 count=8
If you made the backup by copying to a file, then "BACKUP" means the file to which you backup'ed. If you copied to a partition, then "BACKUP" means the partition. The position is derived from the bootsector you posted, which looks good (it was for a partition located approximately 10.5GB from the beginning of the disk, and it has 217GB, which is consistent with what you posted earlier).
If you retry and get the same result, please retry again with the fixed partition, I will undo the fix.
