I need help with data recovery on a ps3?

If there is, I haven’t heard of it. There are no recovery options on the PS3 itself, so getting your saved game back is probably impossible.

Do what I do, back up your saved games on an external source (at least the ones that matter).

You could rip out the HDD and recover the files using data recovery software.

With an professional ipod data recovery tool http://www.ipod-data-recovery.org/)we can recover the lost contents for our ios devices very easy.
