How would I use Watchdog to get triggered when DVD is inserted?

[Daring_T]

I am making a DVD ripping script and I am trying to use the Watchdog Lib to trigger my main function. The problem is, I'm getting this error:

Error:
PermissionError: [WinError 21] The device is not ready.

Is there a way for Watchdog to wait till it's loaded?

This is my test code if that helps anyone and if anyone has any questions feel free to ask.

from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler

event_handler = FileSystemEventHandler()

# calling test functions
event_handler.on_created = lambda : print("created")
event_handler.on_deleted = lambda : print("deleted")
event_handler.on_modified = lambda : print("modified")
event_handler.on_moved = lambda : print("moved")
	
path = "D://"
observer = Observer()
observer.schedule(event_handler, path, recursive=True)
observer.start()
try:
	print("Monitoring")
	while True:
		time.sleep(1)
except KeyboardInterrupt:
	observer.stop()
	print("Terminating")
observer.join()
