Device tracking icon

In the process of selecting one icon out of many and I could use an opinion or two. The context is as follows.

When selecting a file location, the app can be told to make a note of the current device behind specified drive letter and then store it alongside with the path. Should the device get disconnected and then reappear under another letter, the app will adjust the path accordingly.

This is called "device tracking" and the icon on the right is used to access related configuration parameters. Full view of the config window is like this.

Which one fits the "Device tracking parameters" function? What do you think?
