I have a failing Lacie 1T hard drive, and I had them send me another one. But before I wipe and send back the defective one, I want to make sure I have everything on the new one. Using the disk utility I see about a 1.5 gig difference and several thousand files but using the app Compare Folder, it says everything is the same. Is there a program like Beyond Compare for Macs? I use that program at work on pcs, and I love it. I see they're coming out with one for Macs .but chances of it coming out in the next seven days it pretty slim. Any suggestions?
