This is a refurbished drive for PS3, fully working with laser.
Before buying please check which Laser is in your PS3. The KEM450DAA Drive is usually in PS3 Slim with 160 or 320 GB. The 120 and 250GB Versions need the drive 450AAA, which we offer as well. Please check carefully before buying.
Please note that in most cases you don´t need to exchange the whole drive, mostly just the laser needs to be exchanged. The drive you should only change if your drive is mechanical damaged. But you cannot just exchange the drive. On the drive board there is an IC called "SPANSION CHIP". This chip keeps a special code which is only valid for the PS3 in which it was build in the first time. So you need to exchange the whole drive board, or if this is damaged exchange the SPANSION CHIP (good soldering skills are needed).
