What has been happening on this computer recently is this: twice now, when I have plugged in my Maxtor external harddrive (aka the glorified USB drive) I have gotten the error message "The device Generic Volume cannot be stopped. Please try again later." when I used Safely Remove Hardware option to try and remove it.
The first time, it eventually did release the Maxtor, and looking online I found the program Unlocker recommended for if it happened again. It's working...somewhat. The Unlocker Assistant is unlocking things, but Unlocker isn't appearing in the right click drop down menu - and Unlocker Assistant did nothing when I got the message again.
Both times no processes have been running, I checked through task manager, and all files and folders have been closed.
The second time, autoplay did not start up, though I am not sure why. (Autorun has been disabled on this computer, as I had a virus infect that before, but Autoplay is still enabled.) I am not sure if it is related or not, but for the sake of completeness I will mention it. I do not remember if it popped up the first time this happened or not.
I did attempt what was suggested in the FAQ of Unlocker (uninstall, reboot, remove unlocker keys from registry, reboot, reinstall) and it made no difference. Probably missed a key or something - I tend toward caution in the registry.
The computer is an IBM Thinkpad laptop running Windows XP Pro service pack 3.
Mostly my question is: is there any way to keep that message from happening again, what could possibly (in a generic sense) be causing it, and what do I do if it does appear again and Unlocker does nothing?
