Due to my faulty DVD-Rom, I can’t repair my volume header, that scared me for a while. I took my time to look into the internet for the best volume repair software. I get cocktail and some other that are shareware 
And finally I come across this best maintenance software called – Applejack. It allow Single User Mode to maintain and repair the header! It also helps if the laptop can’t boot up. Best of all, it’s freeware! Not even a shareware can compete with this. I got my volume header repaired and now running smooth 
Imagine sitting here all day long just to find out how to repair my volume header, damn! I should have know this software earlier. Next entry must be a weight loss pill reviews due to the long hour of sitting without exercise this few days.
All you need to do is press “Command + S” when startup and the sound “Pong!”. It can’t work when it is on the user mode though. My idea is to just use the command key “applejack auto”, it will do 3 things.
1, Repair header
2, Repair permission
3, Clean up cache
Which is way better to remember all others code 
It is only 331KB file by the way.
