This flash program is for a DVD-ROM drive, this tool will not work with the ND-4571A
This is not something that can be addressed by flashing. You have either connected it wrongly, or broken it.
Try attaching it on its own without the hard drive, or as previously indicated make sure one is jumpered as master, and the other as slave. Make sure the hard drive is jumpered in way that it expects a slave drive. Some drives have several settings, consult the label/manual.
