This indicates that the external hard drive is experiencing serious problems and is unable to perform file transfers. When Windows starts displaying I/O errors, all files and data stored on the external hard drive may be permanently lost.

For disks:

SD card won't open prompting formatting may be caused by abnormal plugging and unplugging, the partition on SD card is corrupted and the data is inaccessible. In this case, do not rush to format the SD card. Because SD cards mostly use FAT32 or exFAT file system, formatting will damage the original data more. When using data recovery software to search for files, try to use deep scan to find as much data as you want.
