Package: ext4magic
Version: 0.3.2-2
Severity: normal
Dear Maintainer,
ext4magic has a misinterpretation of the physical block addresses and block
lengths of ext4 inode.
With each call by ext4magic be other random and too large values dertermined.
Thus, a recover from ext4 file system is not possible.
The error is permanent and 100% reproducible (also on i386)
Often with the additional warning: "error-NR 22 can not found file"
Example:
# ext4magic -T -I2 -x /dev/sdb1 #debian 8.2 (amd64)
....

The block length 25855 and the start block 89219572695840 are random values
and the false block data would also be used while trying a recover.
