Why is there a PE startup tool after formatting my USB flash drive?

This is because the partition is hidden in the U disk when PE is done. General formatting does not work on hidden partitions. You can follow the following steps to restore. First, download and install a general pe toolbox; Insert the U disk into the usb interface of the computer, and then double-click the shortcut icon to start the universal pe toolbox. Starting the U disk in the main window opened by the disk making tool will automatically identify the U disk currently plugged into the computer USB, and then click the "Return" button (be sure to save the data of the U disk, because this operation will delete all the data on the U disk). After the initialization is completed, the current U disk space capacity has been completely restored.
