So i was enjoying some down time for myself the other night taking a nice warm bath and letting my mind wander when i suddenly recalled a time when i worked at a research station and some idiot managed to somehow delete over 3000 excel spreadsheets worth of recently collected data. I was charged with recovering the data and scanning through everything to make sure it was ok and nothing deleted…must have spent nearly 2 weeks scanning through endless pages…and it just barely dawned on me to wonder…exactly…how the hell do data recovery tools collect “lost data”???
I get like a general idea of like how as long as like that “save location” isnt written over with new data, then technically that data is still…there???? I…thats as much as i understand.
Thanks much appreciated!
And for those wondering, it wasnt me, it was my first week on the job as the only SRA for that station and the person charged with training me for the day…i literally watched him highlight all the data, right click, and click delete on the data and then ask “where’d it all go?!?”

To find a file
You walk into the library, go to the card catalog ( yes I’m that old), Then search for the book you need and follow the directions to the book.
Deleting a file is like walking into the library and setting the card catalog on fire and roasting some marshmallows, now you didn’t burn the library, just the instructions on how to find the particular book you need.
When you are trying to recover the files it would be like rebuilding that card catalog by seeing what book is where and rewriting those cards by hand.
Now if you wanted to really destroy those files, you would go to each book and paint over the names and all identification of the book. Essentially you write gibberish over top the files to make them unrecoverable.
