I was given a PS3 slim to work on it will only sometimes load games. The disc goes in the system fine but sometimes makes a noise like it is trying to load it again or eject it. The drive revision is KEM-450AAA as marked on the bottom of the drive after removing the casing. I understand that with the PS3 you have to get the same drive type and just replace the PCB. My question is how do i know which is the right one and can anyone point me in the direction of a place to purchase the proper drive. I have looked on ebay but the descriptions are not good enough to tell me what it really is. the model is a 120gb Slim.
Any help would be much appreciated thank you.
