Is there a program that will help me know where my files are across multiple HDDs that I keep in a drawer? I have a MacMini (late 2012) with 10.8.2 and since I have 10+ HDDs I only keep two attached at a time using docks and switch them out as needed. Only I never remember what is in each. I do not want a RAID as I never need to access all at once and don't need all those discs constantly spinning. I maintain a copy of each drive as a backup.
