Q: I cannot eject my ipod classic after sync with i-tunes on my pc. It states some of the files are being used by other applications. What does this mean? How can I get it to eject?

If it's a one-time "glitch," you can try restarting your computer with the iPod still connected.  Try ejecting again after the restart.

If the problem recurs, you may have a process running (other than iTunes) that is accessing the iPod's storage.  When connected, the iPod's "disk" is like other mounted volumes.  This process may be some type of utility that continously monitors your mounted volumes for security reasons, such as to prevent access by malware.

If you know of such a program that you have running in the background, there may be a setting to exclude your iPod's disk.
