your simple USB memory stick had NO disklabel on it, so OpenBSD made a "pretend" one out of nothing for you. Disklabels are an OpenBSD thing, they don't exist naturally on DOS-only media. > I have attached an externa USB Sarotech disk storage with a 250 GB SATA disk > inside to my OpenBSD 3.8.

You created a REAL disklabel on your disk as part of creating that OpenBSD partition, and it was probably on the disk BEFORE you created the FAT partition, so yes, you have to manually add the FAT partition to that disklabel. OpenBSD won't do that for you. Nick.
