Can't see the root partition

pCP Team 29 October 2020 pCP 6.1.0 FAQ

Windows PCs can’t see the Linux partition on the SD card (or USB device).

Windows will work with partitions formatted as Win95 FAT32 (LBA), so it will see the boot partition /dev/mmcblk0p1, but the Linux formatted root partition /dev/mmcblk0p2 is invisible. For all intents and purposes the SD card appears to be only 64.0M in size.

If access to the root partition is required, there are 2 options:

  • use a computer with Linux type OS.
  • load additional software onto the Windows PC.
  Danger

Depending on the software loaded on your Windows PC, you may be get a series of messages when you plug your SD card in. Always:

  • Ignore formatting requests.
  • Ignore anti-virus warnings.
  • Ignore requests to do backups.
