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?!?”

Think of files like patterns on a zen garden(sand designs). Every new file and information is represented by different patterns on the sand. The files you want to keep hold their pattern.
A zen garden doesnt have infinite space, so maybe you now need to delete some patterns to make space. The way that these patterns(files) are deleted is by designating their space as retraceable. So instead of wiping the pattern flat, you can draw a new pattern right over the old pattern.
So if you delete a file, its pattern still might be on the zen garden if no new pattern was re-traced over it.
