WARNING: Extended attributes are not restored.
WARNING: EXT3_FEATURE_INCOMPAT_RECOVER is set.
The partition should be unmounted to undelete any files without further data loss.
If the partition is not currently mounted, this message indicates 
it was improperly unmounted, and you should run fsck before continuing.
If you decide to continue, extundelete may overwrite some of the deleted
files and make recovering those files impossible.  You should unmount the
file system and check it with fsck before using extundelete.

2、ntfsundelete

NTFS undelete from a Linux system



Requirements

Make sure you've got ntfsundelete available,

which ntfsundelete

Note. it comes with ntfs-3g



Usage

Unmount the volume,

umount /dev/sdb2

Look for fully recoverable files, then for last two monthes only,

ntfsundelete /dev/sdb2 -p100
ntfsundelete /dev/sdb2 -p100 -t2m

Either undelete the precise files you need,

mkdir -p /data/undelete/
ntfsundelete /dev/sdb2 (-p100 -t2m) -u -d /data/undelete/ -i INODE_NUMBER

all the fully recoverable files, for last two monthes, ending with the mp3 extension,

ntfsundelete /dev/sdb2 -p100 -t2m -u -d /data/undelete/ -m'.mp3'

all the fully recoverable files, for last two monthes, for last two monthes,

ntfsundelete /dev/sdb2 -p100 -t2m -u -d /data/undelete/ -m'*'
