Bought for hosting IDE HDD. My HDD is not recognized. They start then stop after a few seconds. After unsuccessful Internet search, I looked all in the housing 1. In the case a label shows that there are actually two different models. One is powered in 12V (mine ...) and another model support 12V and 5V, with a more complicated power connector. Now the IDE HDD must be supplied with 12V and 5V to run correctly. Nothing on the packaging indicates that there are two models ... On the contrary, it says Power Output: 12V-5V-3.5A and 2A. So I asked the return of the product ...
