1. Fault phenomenon
When the SD card is inserted into the computer through the card reader, the prompt "format or not" appears on the computer. When the SD card is inserted into the camera, the "SD card error" appears again, and the photos in the card are not visible.
2. Troubleshooting
When the multi-purpose card reader is used to access the computer, the drive letter of the SD card will appear, and the prompt "format or not" will appear after double clicking. As the multi-purpose card reader is normal, the estimated causes are: SD card has problems, SD card has viruses, SD card file deconstruction is damaged, etc. Since the data in the SD card cannot be read out, format it. After the operation, double-click to open the drive letter of the SD card. There is no data on the card. Then, use the recovery myfiles software to completely format and recover the SD card, copy the recovered files to the SD card, insert the SD card into the digital camera, test and operate normally, and the data recovery is completed.
3. Fault analysis
The recovered SD card was detected by virus detection, and virus damage was excluded. Later, it was tested on the computer and found that the drive letter of SD card appeared. Double click the drive letter and the prompt "format or not" appeared. Check the properties. The capacity of the card increased to 544gb, while the actual capacity was 2GB, so the format operation could not be completed. The SD card is replaced by the multi-purpose reader, and the recovered data is found to be completely correct. Prove that there is a problem with the large capacity display card reader.
