Why does my Flash Drive always blink?
I may be paranoid, but it seems only lately that my flash drive is always blinking when I have it plugged into one of my ports of my four port Belkin that I have plugged into the rear port of my Mac. It's like it is constantly being accessed even when I close out the spread sheet (numbers) files that I was using and even when I close out the main list of directories on the drive. It still blinks. Then when I try to eject it, a message pops up that it won't eject because it is used by numbers. So in frustration and paranoia I just pull the flash drive out of the socket, since I suspect that something in my computer out of my control is reading it. I close out the files and directories by clicking on the red close dots in the upper left. Am I doing the closing wrong?
Thanks for any help even if it's condescending.
