The reasons for memory card unreadability may vary, with some common ones including:
Memory card damage: Physical or logical damage to the memory card may result in data unreadability.
File system errors: Errors in the memory card’s file system can lead to data unreadability. This issue can often be resolved by using disk-checking tools on a computer.
Poor contact: Poor contact between the memory card and the card reader or device can cause reading issues. It is recommended that the contact points of the memory card and the card reader be cleaned to ensure a good connection.
Overuse: Prolonged high-load usage of the memory card may cause damage or performance degradation.
Regularly backing up data and replacing the memory card periodically may help alleviate this situation.
Device compatibility issues: Some memory cards may be incompatible with the device, leading to reading problems. Ensuring the use of a memory card compatible with the device may help address this issue.
When encountering issues with memory card unreadability, it’s advisable to try using alternative devices or card readers to test and determine whether the problem lies with the memory card or the device. lf the issue persists, consider replacing the memory card or contacting app customer service for further support.
