Bought my readers to use CD-ROM to DVD IDE standard only a motherboard with SATA ports, this works well. I bought two, each mounted in position on a master drive and electrically powered with a floppy connector. Do not forget to connect the molex connector or plug 4 pins on your drive to power it. They work seamlessly with my Windows 8.1. In the end, costs less than a repurchase or new readers and can continue to use equipment that is operational.
