Ok, I probably should have looked into this before I did the copy, but I can do it over if need be. I have a large amount of data (~60GB across 1000s of files) that I copied from one external drive to another. At some point, I will be retasking the source drive thus making the original files unavailable.

I've checked a variety of the destination files and they all seem to be ok. However, I'd hate to find out later after the source data is gone that some files are corrupt, etc. Are there any tools that will allow you to compare data after a transfer has been done? Or, is this only feasible at the time of transfer? Any recommended tools out there?

Thanks in advance.
