    Keep in mind there's always a difference between the actual size of data and the size used on the HDD. It has to do with the cluster size chosen when formatting the HDD or a partition, the larger the cluster size and the smaller size of files will create 'slack' space [wasted space] and there's nothing that can be done about that. Regardless of the file size it will take 1 or more clusters for a file and if a file is too large it will take more clusters. Cannot put 2 files in the same cluster otherwise there will be data corruption and lose the file/s. If have a large number of small files a small cluster size choice would be okay but requires reformatting. The default for NTFS is 4096KB so if you have a 760Byte icon file it wastes quite a bit of space.

    That's good info, but I don't think that explains why the total number of files and folders differ between the original and the 2 copies (see attachment)..

    Also, how can I easily compare the folders and spot the differences? I've got beyond compare 4 but I didn't figure out how to use it yet.. Is there an easier way?

    Perhaps you are not authorized to some of the files you are trying to copy?

    You could try to copy it with robocopy and it can generate a log file saying what if failed to copy.

    This command would copy drive D to a folder called "500GB drive backup" on your desktop and make a logfile called copylog.txt also on your desktop.

    Code:
    robocopy d:\ "%userprofile%\desktop\500GB drive backup" /copyall /e /r:0  /log:%userprofile%\desktop\copylog.txt
    You'll get a log something like this saying what it couldn't copy and why:
