2. Are you using a card reader or convertor such as the MicroSD-to-SD convertor or USB card reader to copy SD/MSD/CF…etc? The quality of the convertor and card reader could be unstable. Please try using another brand of card reader. If you need to do a mass copy task, we strongly suggest that you select our professional Flash duplicator. For example, if you need to copy large quantities of MicroSD card, you can try our MicroSD or Combo Flash duplicator. This professional Flash duplicator can highly increase the performance and reduce the risk of mistakes.

3. Slowdown the transmission speed (for Flash 8 Series only)：If you find that the fail rate is high, please select Function 7.9 Working Mode to slowdown the speed of data transmission. It can help you to increase the quality of the copy task.

4. Please do a second copy of the failed Flash. The characteristic of an unstable Flash might cause the data loss during copy. If you find your Flash media frequently needs more than one round of copy, that might be because the quality of your Flash is not stable. You can select Function 7.9 Working Mode to slowdown the speed of data transmission. This can help you to increase the quality of the copy task.
