I also remember, that when doing the dirty trick of trying reading
tracks beyond 35 and then cycling the power, then sometimes the drive
would refuse to read any disks anymore. Only "UI" (or was it (UJ) would
make the drive to bump and return to normal. This also implies it tries
to read the current location, but as it is beyond the formatted tracks,
it gets nothing and decides there is no disk in drive.
