Basically I've got a couple of hundred gigs of photos on one disk (plus backups on another blah). So I'm thinking of reworking my storage options which requires me to migrate photos from Disk A to a new Disk B. I have a dualbay firewire enclosure so I'll probably copy the files with the two drives in there. The thing is, how do I ensure data integrity? I want to make sure the data I have eventually on Disk B at the end of the copy is exactly the same as Disk A. What do you guys recommend? CCC?
