Extract the HFS+ Volume Header


You can extract the Volume Header from the drive to a file with the '--extract-vh' parameter.

hfsprescue --extract-vh <device node|image file> <LBA sector> [--vh-file <output file>]

Beside the device node or image file is the LBA sector number required to extract the Volume Header. When you don't know the LBA sector number, then it's possible to find the Volume Header. See Find the HFS+ Volume Header or Alternate Volume Header and the partition start offset.

You can use the Volume Header file in program modes like '-s1', '-s3', '--one-file' and others.

The default output file is './restored/VolumeHeader'. You can specify another output file name with '--vh-file'.


Sample command: hfsprescue --extract-vh /dev/sdb 409642
