From what you describe, you don't have the bug.

To diagnose this bug, you put a write-enabled disk in the drive and open
a window on it.  Then you wait for the access light to go out.  Now take
the disk out and put it back in, then hit escape.  If the drive doesn't
spin, you have the bug. 

For TOS 1.4, diagnosis won't be so easy, because hitting ESC on the
desktop ALWAYS causes the disk to spin -- it causes media change on the
drive, to take care of the possibility that you changed the disk while
it was out of the drive. 

In the case of write-protected floppies, it is normal for the ESC key to
cause a quick response if the drive was accessed within the last second
and a half: this is a "grace" period so we aren't checking the serial
number on every single access.
