Hard Drive

Overview

Connecting a hard drive to the PS2 requires a Network Adaptor.

All official hard drives run special firmware, that implements some additional proprietary ATA-commands. Thus, official software requires official Sony PS2 hard drives. Homebrew software such as OPL does not require any of the proprietary commands, which means that a generic hard drive can be used as well for this purpose.

The PSX's internal hard drive implements the same proprietary ATA-commands, which are required for the console to boot. That's why the PSX's hard drive can only be replaced by another PSX's hard drive or one of the official Sony PS2 hard drives (which however only have a capacity of 40 GB, vs. 160 GB or 250 GB in the PSX).

For external hard drives (used with early SCPH-1X000 consoles), a special expandable vertical stand (SCPH-10220) was available separately, which allowed the external hard drive to be placed vertically next to the vertical PS2 console
