I have Raspbian installed on my Pi. I want to create a FAT32 partition on the unallocated space on my SD card. I followed this guide to create a partition. The partition is readable/writable on Raspbian and Mac OS without any problems. However, the partition does not show up in Windows Explorer. I opened Disk Management on Windows and found that this is no drive letter assigned to that partition. And Disk Management does not allow me to assign a drive letter to it.

  • Why not just create the partition from inside Windows? (instead of on the Pi itself)

  • @tapped-out: Disk Management does not allow me to do that.

Windows doesn't know to look past the first partition on an SD card, so won't find the one you made.

  • Yes it does, but it sees it as 'unknown partition rather than the fat32 partition that I created using gparted

  • Alright then: “Windows cannot read data past the first partition on an SD card.” Happy now? The only difference is semantics.
