That's really funny! :)
I've decided to see if my floppy drive is working at all, but when I
was inserting a disk in it I noticed that there already was one. :)
Then I've tried to mount that one, but the mount utility hanged. The
other disk is working with no problem.
So, the problem was that strange floppy disk sitting in my drive.
I'm really sorry for bothering all you guys! The real problem was (and
still is) my inattentiveness.
P.S. This floppy disk does not cause a hang in windows, so I may
suppose that there is a bug in fdc! :)
