What to do when ps3 says cant find hard disk?

May be...

my ps3 keeps saying cant find correct hard disk but sometimes it does work but mostly no and iwant to know if i can fixe it myself or do i have to send it to sony please help

First, call Sony to troubleshoot. They'll walk you through it.

It's probably easier to send it to Sony but it's a bit expensive. I would take it apart myself but is very dangerous.

lift it carefully with your four finger from each side of console , lift it about 1 feet from the surface then open your fingers just drop it back ,where it was ..and look what happens .....!!









it is a joke man do not do it !

When it works reformat the console ?

Send it to repair.
