Hello TVeblen, thanks for your reply. Actually I am confused. As far I know, when we eject USB device from the USB icon in taskbar or notification area then we will get a confirmation pop up "Safely remove USB device". Generelly, what is heppend here. I know operating system disconnect it from power. But now I want to say when I eject my pendrive (twinmos) by click "eject USB device" from the taskbar than I will get Pop up "Safely remove USB device", that's ok. But problem here it is not disconnect from power. In windows XP I saw when I click "safely remove" than it is eject from computer and it is not flashing, that's ok. But in windows 7, after complete the safely remove by click the eject USB device, I get a confirmation pop up that's ok but it is still blinking and it is connecting to PC not pulled. Generelly what would be should now, it is disconnect from power, but it is don't disconnect.
Actully I am sorry for annoy.
