It does initialize the disk in any case. The check it does is for a flag in
the burst command that does suppress the initialization. I don't remember
which bit it is, maybe bit 7 or so. So instead of sending U0>M1 you would
send "U0"+CHR$(x)+"M1", with x being the correct value. A look into the 1571
manual should reveal the correct value.
