Confirm the pin assignment of the 4-pin connector and the mating header before installation to avoid reverse polarity or miswiring.
Ensure the total current of the drive does not exceed the rating of the power wires, connector contacts, or PSU rail.
Avoid excessive bending, twisting, or compression of the red SATA ribbon and twisted power bundle, especially near the connector overmolds.
Keep SATA data lines away from strong electromagnetic noise sources such as motor or high-current power cables.
Check that all connectors are fully inserted and latched; periodically inspect the harness for signs of abrasion, cracking, or overheating in long-term high-duty applications.
