If a memory card cannot be read by any device, what could likely be true?

The assertion that the memory card is damaged, and its contents are permanently lost reflects a possible scenario, particularly if the card cannot be read by any devices. Physical damage can lead to a total failure of the card, making it inaccessible and causing the loss of data. Hardware issues, such as broken connectors, internal failures, or exposure to extreme conditions, may result in this situation.

However, it's important to consider that there are other potential reasons a memory card might not be readable. For instance, a corrupted memory card can also be unreadable without necessarily being permanently damaged. Similarly, a card that has been reformatted may not be read by devices expecting files formatted in a previous structure, and obsolescence due to an older card model doesn't inherently mean it is unreadable; many older cards can still be functional if the appropriate reader is used.

Therefore, while the scenario of irreversible loss due to irreversible damage is plausible, particularly if no devices recognize the card at all, it does not wholly encompass all possibilities related to a non-readable memory card.
