Very likely he was playing with power supply cables or has changed the power supply without using the included cables or it was just faulty.
ATX power supplys cables not have always same configuration!

When we see those burning marks on WD drives on that specific side of smooth chip often is also a sign of burned preamp.

I fear that the preamp may have been damaged.

Check the TVS diodes.

On this model, preamp damage is very likely.
