The proper removal of external storage devices, such as SD cards, from macOS-based computers is essential for data integrity and preventing potential hardware issues. Abruptly disconnecting an SD card during a read or write operation can lead to file corruption or damage the storage medium itself. Therefore, following a safe ejection procedure is crucial.
Safely removing storage devices protects against data loss and potential file system errors. The process ensures that all ongoing read/write operations are completed and that the file system on the SD card is properly unmounted. This practice has become increasingly important as data storage density increases and the potential for data corruption grows with improper handling.
