What should I do if the USB Flash Disk fails to read or write after a normal installation?
There are two possible causes: (1) If you can read data from the disk but cannot write, this is mostly because the disk is under write-protect state, or the storage space is full. Delete some documents, and you can continue to use it. (2) The malfunction may be caused by power-off or improper pulling out of the USB Flash Disk. Simply reformat the disk.
