Hard Drive
Overview
Connecting a hard drive to the PS2 requires a Network Adaptor.
All official hard drives run special firmware, which 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 allows the external hard drive to be placed vertically next to the vertical PS2 console.
Official PS2 software does not support 48-bit LBA, so drive size is generally limited to 128 GiB. In practice, this doesn't matter much, since the only drives supported by official software are the official drives sold by sony with their firmware customizations, which are all 40 GB in size.
Most homebrew software supports 48-bit LBA, so this isn't an issue here.
DVRP of the PSX will emulate the PS2's ATA interface for PS2-mode software (while PSX-mode software obviously natively uses the PSX's ATA interface, which supports 48-bit LBA, since the drives have a capacity of either 160 GB or 250 GB). For some reason, it also tries to emulate 48-bit LBA in PS2 mode and properly reports the full disk size, but fails any access beyond the 128 GiB limit in PS2 mode.
