Actually, it's a bug in windows. Whodda thunk? :) The problem is Windows sees a "removable" device, and it is ready for multiple partitions...but it only seems to recognize the FIRST partition as something than it could work with. So..it tries to make sense of the OpenBSD partition, fails, and doesn't look past it to see the Windows partition. SO, the secret is to put your Windows partition on the flash media first, then OpenBSD. You can create the partitions with OpenBSD, just make sure your Windows partition is before your OpenBSD partition. In fact, you probably will find you NEED to create the partition in OpenBSD, as Windows sees a USB flash drive and makes assumptions about what you are going to do with it. Once your partition exists, however, Windows can format it. I prefer to format media with the native OS. (The observant will note that I've not made it clear if it should be the first physical partition on the disk, or the first partition in the partition table. I'm not sure which it has to be. Feel free to experiment, but I've just always made Windows first in both, at least after the last time it bit me, when I was 100+km from home dropping off some systems for a friend of mine that I *thought* were sufficiently tested...and without the stuff needed to rebuild the flash media properly. That makes it so much easier to remember :). When done, Windows will see one partition, and it will be usable. Note: this isn't just USB thumbdrives, it is also CF flash media in a USB adapter. Not sure about USB HD (no idea) or CF in an IDE adapter (I'm guessing it would be ok with that). Just don't sit on that $20 thumb drive, at least, unless you can resolder the joints between the USB plug and the circuit board. :) Nick.
