So what's going on during your formatting attempt:
The tape driver hardware generates an interrupt at the start of each
segment is has to format (and one at the end). Ftape catches those
interrupts feeds the FDC (floppy disk controller) with the necessary
data for the next segment.
Apparently, this does not work. BTW, does reading and writing work?
Are you sure that you have configured ftape to use the right interrupt
line?
I think you should have a look at the kernel log file and see whether
there are any error messages produced by ftape.
Also, ftape reports the kind of FDC it has found, and the timings for
the I/O to the floppy controller like so. Maybe the corresponding
information from your log files gives some hints. (BTW: switching to
version 4.04a will not help you, but you should use 4.04a instead of
4.04 because the newer version fixes a bug in 4.04 which can cause a
kernel Oops when accessing /proc/ioports after the driver has been
unloaded)
