The dude was typing a bunch of commands into the DISKPART without explaining what they did; and I was blindly following him, ended up wiping my main drive with the "clean" command :L

The "clean" command In Diskpart, wipes the disk but does not zero out (overwrite) Its contents, so there's still the possibility to recover ex-amount of data.

If you used the "clean all" command, every sector on the disk will be overwritten, hence zero chance of recovery.

Tbh I dont even know what one I typed. Ive already accepted the loss, I only loss programs and those are re-downloadable so ive accepted it at this point

I understand your position.

Do perform regular/Incremental backups on multiple external drives- and not just the one. I've had countless SSDs and USB sticks crash to the point of losing functionality. Thankfully, I had my data (and still do) backed up on three external devices.
