Hi, Recently purchased a Western Digital My Passport Essential 250 Gb Hard Drive. I am backing up my computer files and when I click on the Safely Remove Hardware icon a message comes up stating that the 'Generic Volume cannot be stopped right now, try again later'. I have no other programs running and have finished copying to the WD hard drive. I don't want to just unplug it from the USB slot in case this causes any damage. Hence, I wondered if anyone can offer any advice please? Thanks in advance.
