HFS+ Fix

Simple program to make HFS+ Volumes Read-Write mountable on linux.

WARNING

This program disables the journal, which may result in data loss!

Compiling:

make

Usage:

sudo ./hfsplus_fix /dev/sdX

What it does:

• Disables the Journal
• Sets the 'unmounted' bit
• Sets the 'lastMountVersion' to H+Lx or your own input
• Zero's the Journal's block number

This should make it mountable as read-write on linux using hfsutils/hfsprog
