How Does Lightroom ID different ext hard drives ?

[fparsons]

In the tutorial dowloaded it was mentioned that the speakers had 13 or 14 hard drives.  When Lightroom says a file is "off line"  how do you know which external hard drive the file is in ?

Give each drive a unique name and Lightroom will provide this info in a dialog.
