I have a 4GB Kingston DataTraveler USB drive. When I tried to use it this afternoon, it showed up nothing in there but yet its details showed that 3GB of the capacity was in used. Apparently, the drive is working but somehow not showing my previously stored data. I cannot delete the files in my USB drive. Did the files/folders get marked as hidden? Follow the steps below and you will manage to solve the problem.
Check if the files are not in hidden mode.
Click on "Start" -->Run --> Type cmd and press Enter.
Check where your pendrive drive ? Some people pendrive drive in G. My pendrive drive in F:
Enter this command. If your pendrive drive in F
attrib -h -r -s /s /d f:\*.*--> Press Enter
Enter this command. If your pendrive drive in G
attrib -h -r -s /s /d g:\*.*--> Press Enter
You can copy the above command --> Right-click in the Command Prompt and paste it.
Now check your pen drive for the files, you can view in the Recycle Bin Folder in your pen drive.
