[FLOPPY]

[FLOPPY]
When discovering floppy controlers, immediately probe controlers to check whether they have a disk and if so, what's its geometry.
This avoids waiting for the first read, which will obviously never happen because FSD will try other operations depending on not set geometry.

This implies a modification in RWDetermineMediaType() to avoid infinite wait, in case there's no disk at all in the controler.
