As noted, the pictured red lead is the slim data cable used by modern disk and optical drives. A few clarifications for and anyone reading this later: that thin cable carries data only. The drive still needs a separate power feed from the power supply — older systems used a 4‑pin peripheral (Molex) power plug while SATA devices use a different, wider power plug with more pins. See the SATA specification for connector differences and power details Serial ATA.

The four wires on a Molex peripheral power plug are color coded for voltage rails. Typical wiring is:

  • Yellow = +12 V
  • Red = +5 V
  • Black = Ground (two wires)

This is why you see different colors on the Molex cable; they indicate different voltages, not data lines. For the Molex wiring and pinout, see Molex connector.

Practical checks: if a drive does not spin or is not detected, confirm both a data cable and a correct power connector are attached; try a different SATA port or cable; check BIOS/UEFI drive detection; avoid forcing keyed connectors and do not mix up power/data plugs. Adapters (Molex-to-SATA power) exist but use them only when needed and verify voltages.
