How can you remove mount error of memory card?

To resolve a mount error on a memory card, first check for physical damage or dirt on the card and the card slot. Try reinserting the card into the reader or another device to see if the error persists. If that doesn't work, connect the memory card to a computer using a card reader and run disk checking tools to repair any file system errors. Additionally, ensure that the file system is compatible with your device, as reformatting the card may be necessary, but it will erase all data on it.
