Move orphan inode(mft entry) to lost & found directory #4

namjaejeon · 2022-11-10T05:39:35Z

Currently we just remove orphan inode(mft entry), We need to move it to lost&found directory.

This message is comming after merging the recent PR to #master. Parse #4: Check mft entries in volume... Clear the bit of mft no(447) in the $MFT/$BITMAP corresponding orphaned MFT record (y/N)? N It mean fsck try to clear bits of external mft entry. When fsck set bits of mft entries, the call of ntfs_inode_attach_all_extents is missing about inode that included attrlist attribute. So fsck decided external mft entries are orphaned. This patch add the call ntfs_inode_attach_all_extents() before checking ->nr_extents and ->extent_nis.
