Hi,
First open Service Manager and ensure that the Bluetooth Support Service is running and set on Automatic. Next, open Device Manager and open the Properties box of Disks. Under Policies, ensure that Enable Write caching on the disk is checked. This should then actually work.
Now right-click on the USB Drive (in my case HP USB device) and from the same location in the Properties, change the default setting and select instead Better Performance. See if this helps. Now go back to the default Quick Removal setting again. If it does, great!
But if the Safely Remove Hardware dialog box is still not appearing, when it should, in Windows, rather then just removing the hardware and risking possible data corruption or loss, just bring up the Command Prompt window and type the following:
rundll32 shell32.dll,Control_RunDLL hotplug.dll
Then hit ‘Enter’.
The Safely Remove Hardware dialog box will now appear !
Hope this helps you.
