In the media industry we tend to spin a lot f myths and magic around what is in essence tech and science. That isn't strange.
At the heart of all we are artists, not scientists.
But when something as basic as validated copies gets confused by myths, you end up risking your files. Somethings can not be done faster than physically possible, and what "hash" you use isn't the key element.
Thus we did this writeup to de-confuse what is needed to do a verified copy, what it is and how you can test our and others software as to file-security. The matter has become so confused that we clearly cannot trust "approved by" statements.
Yup it is a bit technical, but the point is important.
I hope this is OK to post, as what is in the article can be used to test any software, including our own.
