original title: error code 47... do not see the ball, confirming that its safe to remove hardware

Lately, I did not remove my USB devices. Whenever I right click on safely remove and remove the material, it does not show a balloon, saying that it is now safe to remove the material. When I "Devices and printers" it has the feature still listed with an exclamation mark next to it and bed the error code

Windows cannot use this hardware device because it has been established for "safe removal", but it has not been removed from the computer

Error code 47

There is a work around that I guess by going to my computer and ejecting the disc from there, but is there a good way to solve this problem, while the ball themselves. I also hear USB connect/disconnect sounds randomly even if I am not connect or disconnect any USB devices
