The product is well tested in the sense DISK SATA IDE port. one downside: no installation instructions. Although it may seem obvious, it would still indicate that the adapter requires a clean supply different from that of the hard disk to function. We must plan a Y if there is only a molex available to power the adapter and the IDE drive. It would have been wise to think of a fitting that makes the dual power. Also this adapter is mobilizing an IDE controller itself and therefore can not install two IDE devices on the receiving controller adapter. I did not test in the sense DISK IDE SATA port.
