Being a hybrid of a DVR and a game console, it has a lot of unique traits. Sadly, it has a lot of reliability issues, most notably nowadays dying Hard Drives and Disc Drives. This article aims to make repair easier and collect information that might help in circumventing the HDD vendor-lock in the future. It also aims to be a general collection of information on reverse-engineering of the PSX. | ||

The whole drive assembly is connected to the motherboard using 3 flat flex cables: One is an IDE connection to the dedicated drive board of the PSX-part, one provides power (5V, 12V, GND) and also connects the PS2-part sled motor to the motherboard (since it is controlled by the motherboard directly), and one connects the KHS-400C PS2-part pickup to the motherboard, since it is also directly controlled by the motherboard. The spindle motor is always controlled by the dedicated PSX-part drive electronics over IDE, even in PS2 mode. | ||
Two different models have been made; the older one is used in DESR-x000 and x100, the newer one in DESR-x500 and x700. The drive has an updatable firmware for the PSX-mode part of the drive; at least the newer drive actually received such an update (Sony model name: DW-DX02A, known firmware versions: 0YX7 Sep 15 2004, BV1M Mar 08 2005). | Two different models have been made; the older one is used in DESR-x000 and x100, the newer one in DESR-x500 and x700.
