"Problem ejecting USB mass storage device" (or so says Win7)
I've noticed a problem lately when backing up my W7 computer. I plug in my 1TB external HDD, get everything backed up, then click the icon in the tray to allow me to safely "Eject USB mass storage device" (i.e., my HDD). No matter which external 1TB HDD I use (and, if memory serves me, on some 4GB flash drives as well), I now get the following warning:
I carefully close any programs that (I think) could have even the remotest reason to keep the HDD active, but no luck. I still get this message, so I end up having to shut down, remove the HDD, and reboot, which is profoundly annoying and inconvenient.
Any thoughts on what's causing this and how to cure it will be much appreciated.
