Every time I plug in my phone via USB it automatically mounts the SD card I have a Motorla Droid running CM6 (essentially Android 2.2).  I'm connecting to Windows 7 machines via USB.  Every time I plug in my phone via USB it automatically mounts the SD card as external storage.

How can I stop this behavior?  I haven't really noticed when it started, sometime after I installed CM6?
Apparently the Winamp app has an Enable auto-mount setting that is by default set to true.  Problem resolved.
