02bin3, Very strange! You can continue to use it but the option to safely remove it via the icon is not displayed.I would not remove it now until you can overcome that loss of "safely remove". That is the prevailing concensus of the research i had done some time back. Others have claimed they seldom if ever do it that way and don't have problems. However interupting a removable HDD when in operation by removing it can cause a loss of all data. A couple of things i would suggest. Try another device such as a USB flash drive or whatever and see if it brings up the icon option. The other is shut down your computer with the external still connected and running through the "start" shut down method. Then with the computer off--turn off the power supply on the rear of the external via the toggle switch. Then turn on the computer. After the computer is fully functional then turn the external switch to on and see what happens. If that doesn't restore the icon please refer to this article it provides work around and reintroduction of the icon.let us know what occurs as you work through this. goodluck,truenorth
