I ordered a replacement drive, model APPLE 661-0345

however what I received in mail was:

Sony model MP-F51W-23

My Mac II running 7.1 with this drive cannot read any of my old 800k floppies. See picts.

Does anyone know what the problem is? Did I get the wrong drive?

Thanks very much I hope you can help. I've googled until my fingers hurt

I should also add that any attempt to initialize a floppy always (no matter what) gives me error that disk is write protected, even if it's not.
