We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Checking file integrity after copying using Teracopy (alien.top)

Hi all! I've been transferring a bunch of stuff from my portable harddrives to my synology. After transferring using Synology's file transfer and connecting the harddrive directly, I've completed a handful. I started worrying about the file integrity of these transfers since synology really doesn't tell you what files failed and etc. So I started using Teracopy to transfer all the files instead. Can I use Teracopy to verify files that are already transferred that didn't use Teracopy?
Like plug harddrive into PC, and then "Source F:\" and "Target Nas location" and click verify. Does that work... sorry very new to data hoarding. Thanks in advanced

In Teracopy, choose your files, Test and save a HASH. You'll need a program like MD5Checker to compare the HASH.

I like ViceVersa for comparing drives/directories. The free version should be fine unless you have non-English file names. https://www.tgrmn.com/free/
