All the USB Ports are OK because i use USB Sticks and Jailbreak. Everything work correct. Searching the internet somewhere I read that cannot read USB 3.0 without external power supply. My hard disk has only one cable to connect to USB. No power supply... Now I am trying to format again to Fat 32 with another program.

Edit: Found a solution... PS3 does not work with USB 3.0 devices...

The reply from Sony: "Yes, it does not work with USB3.0 devices. It's been stated in the article and in the User Manual of the PS3."

Hope that this helps the others!!
