Just try any of the slots with an mp3 song in a compatible card
Can you tell me more about your blue ray drive? I wish we could turn our consoles into something useful again. I hope there is soon an update to load backups without the need of all of the internal hardware components.
Mine is totally messed up, I cannot detect any disc to begin with so it wont suck them in, It disables the eject beep (although the eject function for activating psjailbreak works)
Technician diagnosis is death of the main board of the drive.
