click start click to open on my computer you should see your usb drive E: right click select properties there will be an array of options select the sharing tab option then advanced sharing make sure you have a tick in the share this folder box then click permissions make sure you have all 3 boxes ticked full control changes and read in windows 7

click start control panel user accounts click on the administrators account if you have made one or you will have to create one in windows
  • click start right click on my computer select open
  • Right click the icon of your Hard Drive (It should be C:/ or something)
  • Click Properties in the menu that comes up
  • Click the Sharing tab
  • Click permissions
  • And finally, click Allow next to Full Control.

Did you check if PQI USB has write protection switch

With PQI logo facing upwards
puch the switch to the left
This should disable write protection

If that doesnt work

To remove write protection:
Open Start Menu >> Run, type regedit and press Enter, this will open the registry editor.
Navigate to the following path:


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies Double click the key WriteProtect in the right pane and set the value to 0
In the Value Data Box and press OK button
Exit Registry, restart your computer and then again re-connect your USB pen drive on your computer.
