What lessons can we take away from my story? They are, in fact, quite simple and obvious: merely deleting files and quick formatting is usually not enough when disposing of or selling hard drives. For more assurance, it’s better to perform a full format (in modern operating systems, of course). And for the truly paranoid, there’s the good old console utility SDelete from the Sysinternals suite or a tool named... - Source: dev.to / 8 months ago

I assume you were using a dynamically expanding disk - if so just note it won't dynamically contract just by deleting files. To shrink the drive you will likely need to run sdelete -z on the drive inside the VM to clear the free space, then edit and compact the VHDX. You will need to be able to boot the VM to run sdelete though so you'll need to temporarily move other files off the drive, or move the VM files to... Source: about 1 year ago

You can always download sdelete https://learn.microsoft.com/en-us/sysinternals/downloads/sdelete and do an overwrite pass just to be safe. It'll take a while but you can do other things while it's running. Source: about 1 year ago

My understanding is that it doesn't completely solve it. I don't have time to dig up an authoritative source for this claim — hopefully this superuser comment will suffice. I believe that you can achieve something close to a secure erase by filling up your SSD to 100% capacity with data before deleting; the utility sdelete supposedly does this when using the -c option.

I've used Czkawka (https://github.com/qarmin/czkawka) because it does Lanczos-based image duplicate detection, which makes it more practical for me. - Source: Hacker News / 8 months ago

Maybe it's a setting you made or the files, not sure. You can try another software czkawka to see if you get better results with it. Source: 9 months ago

For static images I used https://github.com/qarmin/czkawka and it works well enough. I think. But when I used it on a folder with gifs and their jxl conversions, it shows nothing. SURELY this could not be user error, rrrright? Source: 10 months ago

I used to use DupeGuru which has some photo-specific dupe detection where you can fuzzy match image dupes based on content: https://dupeguru.voltaicideas.net/ But I switched over to czkawka, which has a better interface for comparing files, and seems to be a bit faster: https://github.com/qarmin/czkawka. - Source: Hacker News / 12 months ago
