$ cd
$sudo umount /mnt/TEST_DRIVE

Now that we’ve got deleted one of the crucial information (which we’ll think used to be carried out by accident), to view the entire information that existed within the instrument, run the --dump-name possibility (change /dev/sdb1 with the true instrument call).

In addition, we will additionally repair information inside a given time frame. For instance, merely specify the right kind date and time period as proven.

$ ext3grep --restore-all --after `date -d 'Jan 1 2019 nine:00am' '+%s'` --before `date -d 'Jan five 2019 00:00am' '+%s'` /dev/sdb1
