+====Eject USB Stick/drive Issues====
+If you try to eject a USB drive and get message "drive wasn't ejected because one or more programs may be using it" here's some things you can try.
+Suppose drive is called DD1.\\ (You would run these commands in Terminal.)
+===What processes are using the drive?===
+''sudo fuser -u /Volumes/DD1''
+===Info about the process===
+Suppose the command above returns process ID 129.\\
+''ps -fp 129''\\
+A process with /System/Library/ in the path is a system process.  If it's in /Applications/ then it's likely a third-party app.
+===Command that started the process===
+''ps aux | grep 129''
+===Parent of the process===
+''ps -o ppid= -p 129''
+===If the process is something 'mds'===
+A process with ''mds'' in it means it's a Spotlight app.  To temporarily exclude the drive from Spotlight,\\
+''sudo mdutil -i off /Volumes/DD1''\\
+or\\
+System Settings > Spotlight > Spotlight Privacy\\
+Click + and select DD1, and add it to the list.
