Why does this happen? The failure can be traced to two main sources: physical damage and controller logic failure. Physical damage is common. The SD card's thin circuit board is vulnerable, especially when used in devices with card slots that don't fully support it. A common point of failure is the area just behind the contact pins, where the card can develop a tiny, often invisible crack.

: Many "fake" SD cards use modified firmware to report a high capacity (like 1TB) when they only have 2GB of actual space. Once you exceed that 2GB, the card crashes and reverts to its true, smaller size, often showing Power Failure
