How much time will it take to repair a USB flash drive after using the cmd command chkdsk, etc.?

It depends on the actual condition of the USB flash drive, if there is physical damage or there are more bad blocks, the time to be longer, if not, the time to be shorter; the capacity of the longer time, the capacity of the shorter; chkdsk add / R parameters with longer, not add the time to be shorter. In my experience, it usually doesn't take more than 5 minutes
