Hello all and thank you in advance.
I have a bunch of different hard drives and have backed up a copy of my families cds and dvds on them. When I buy a cd or dvd I always try to make a copy on a hard drive in case the poor disc is stepped on or put in the dish washer or who knows what?
My question is about comparing these hard drives against each other to see what I may have backed up more than once. I may have backed something up and on 1 or more other hard drives and the same cd or dvd may be backed up by the son or daughter not knowing I did it. Any hints on good programs to compare these drives?
