So i found this old hdd in an even older computer from the 1990's, and i connected it to my pc via an sata to ide adapter, and i connected the molex cable. It worked fine, and i formatted it to use it in my windows 98 machine. But then i noticed something odd on the back interface of the drive. There was a small socket between the IDE and Molex interface. I first tought it was the jumper settings, but it only had 3 connectors, and no jumper. I found out the jumpers were placed in the bottom of the hdd, in the PCB board, so i began to wonder what it was used for. on the PCB it says that the three connectors are GND, +12V and +5V, so i wondered if it could use another power input instead of the molex? i have never seen this before, and didnt find anything on the internet about it. it is a Quantum Tailblazer 3.5 series 840 MB HDD wich came from an old IBM computer. So am i right that it is a power input, and if so, how could i use it? could i use it instead of the molex input?
Also, my english isnt very on-point, so sorry for spelling mistakes.
