    I'm running El Capitan on a 2013 iMac. I need to copy a lot of data from several external USB 2.0 drives (Windows NTFS format) to several 3GB external USB 3.0 drives (Mac OS Extended Journal format). This data is "mission critical" and I need to be 100% sure that it copies correctly.

    Whats the best way to do this? Are there any Mac programs that copy and do checksums to verify the data integrity of the copy? Or is there anything build into OS X that can do this natively?

    For reference, on Windows I use a backup program called SyncBack to do this kind of thing.

    Thanks.

    I would try CarbonCopyCloner or SuperDuper.
    Either can be downloaded free.
    CCC is fully functional for a 30-day trial. Should do what you need to do.

    Disclaimer:
    I've never tried to clone a "non-Mac-formatted" drive with CCC.
    I don't know if it can clone an NTFS drive to an HFS+ drive.
    But give it a try -- it will "cost you nothing" to do so.

    And...the Bombich website has a lot of info on what CCC can and can't do.

    CCC and SuperDuper do not work cloning NTFS to HFS. And when copying NTFS to HFS you may run into "ownership" and permission problems.

    I have an idea that might be better than the disk to disk copy...

    Copy all of the files from the NTFS drive to a Windows 10 machine's local hard drive. Network the Mac and Windows machines together Copy the files from the Windows PC to the Mac over the network. I read somewhere that the network copy protocols have built in error checking.

    Any comments would be welcome. Thanks.
