The PSP has 11 partitions, three of which are external drives, the other being partitions on the NAND:

  • ms0 - Memory Stick
  • flash0 - Flash Memory (Contains all the firmware files)
  • flash1 - Flash Memory (Used to store the XMB settings, network configurations and the background image in 2.00 and above)
  • flash2 - Flash Memory In firmwares 3.00 and up, this contains the half of the DRM for Sony's official PS1 emulator (the other half being in the flash0)
  • flash3 - Flash Memory Currently unused and about 1 MiB in size although in custom firmwares it can be used along with flash2 to redirect firmware elements such as fonts.
  • flash4 - Upon examination of the 3.71 firmware, it was discovered that there were references to a flash4 and flash5. However, they cannot be mounted. It is suspected that they are unformatted and may be for future use hence why they cannot be read.
  • flash5 - same as flash4
  • disc0 - UMD Drive
  • ipl - Initial Program Loader
  • irda0 - Infrared Port (Not present in PSP 2000)
  • idstorage - Contains the IDStorage keys specific to the PSP hardware. Damage to the keys can result in homebrew and UMDs no longer running.
