Ah, so, right, aha, yeah (he said, nodding, pretending to understand DOS partitioning :-) Actually, I think I'm getting some of this. So, DOS disks always have four partitions (some of which can have zero size). Slices 5..32 (NDOSPART+1...MAX_SLICES) are *inside* extended partitions (or recursively inside other slices). wd0s5 doesn't come after wd0s4 (as a UNIX weenie might expect); it is inside the first extended partition (whichever of the four that might be.) s6 would be either after s5 inside the same extended partition, or on the next extended partition, or even inside s5. Trying to mount an extended partition is silly; what I want to mount is one of the logical drives inside it. Hmm, it's too bad extended partitions don't seem to have an obvious magic number so that mount code could notice what is going on and tell the user. > >dev/wd0s3 is DOS D: and can NOT be mounted from FreeBSD. > /dev/wd0s5 is DOS D: and CAN be mounted from FreeBSD. Right you are, wd0s5 works. Thanks! ++sja
