Gpart (not gparted) under FreeBSD has problems to add a FAT32 partition when using GPT (works with MBR).
This is the disk:
% gpart show /dev/da0
=> 40 15257520 da0 GPT (7.3G)
40 15257520 - free - (7.3G)
But now I get an error:
% gpart add -t fat32 /dev/da0
gpart: Invalid argument
How do I create a FAT32 partition with a GUID Partition Table under FreeBSD?
