A recent post in the PC section of the Reddit forum has captured widespread attention. User HellBlade64 inadvertently connected a non-standardized power cable, resulting in the immediate failure of a 14TB Seagate Exos X16 hard drive—a device that housed 14 years' worth of irreplaceable data. The hard drive could not be powered on, and all the cherished videos, game recordings, and other valuable data that had not been backed up were irretrievably lost. Tomshardware suggests that the core issue stems from a lack of standardization among power supply manufacturers. Even within the same brand, variations between different models can lead to significant discrepancies, including completely different pin configurations for cables. This incident serves as a stark reminder to users: avoid mixing power cables unless compatibility is explicitly guaranteed by the power supply manufacturer.
