Because nothing says "peace of mind" like knowing your ex can't recover those embarrassing selfies from the hard drive you gave them. Because nothing says "peace of mind" like knowing your ex can't recover those embarrassing selfies from the hard drive you gave them. Your Deleted Files Are Living Their Best Life Without You Imagine this: On an online marketplace, you recently sold your old laptop to a total stranger called "GeekWizard99." Decluttering and having more money in your pocket make you feel fantastic about the transaction. But hold on, did you really remember to erase those fanfiction drafts you wrote at three in the morning or those financial spreadsheets called "Secret Millionaire Plan"? Plot twist: pressing "delete" tells your computer, "Hey, I don't need to SEE these files anymore, but definitely keep them around for someone more tech-savvy to find later!" It's similar to being awful at hiding in a game of digital hide-and-seek. The digital version of a paper shredder on steroids is called diskEraser. Instead of being brushed under the rug, it's here to make sure your digital skeletons remain buried forever. What diskEraser Does (Without Making Your Brain Hurt) diskEraser Think of diskEraser as that one thorough friend who doesn't just clean up after a party—they steam the carpets, repaint the walls, and make sure not even DNA evidence remains. Except in this case, the "party" is all your digital data. This free tool: Annihilates Your Data: Not just "delete" but "delete FOR REAL delete" Works Everywhere: Hard drives, SSDs, USB sticks, memory cards, probably even devices we haven't invented yet Formats After Destruction: Like burning down a house and then building a new one on top—just less illegal Won't Accidentally Destroy Your Life: Smart enough to say "Umm, that's your main drive with all your current stuff on it.

You make a drawing and then shake it to remove it. However, if you use specialized tools or look very closely, you may occasionally still be able to detect faint remnants of your work.In addition to shaking the Etch A Sketch, diskEraser also fills it with glitter, shakes it again, fills it with sand, and most likely does a ceremonial dance around it. Upon completion, even the FBI would simply shrug and declare, "Yeah, there's nothing here." For Fancy New Solid-State Drives (SSDs) SSDs are like that one friend who always remembers your humiliating moments. They need a different strategy.diskEraser basically uses sophisticated cryptography techniques to confuse their brains rather than attempting to make them forget (something they are obstinate about). It's similar like substituting sporadic episodes of static TV for all of their memories—technically, something is there, but it's meaningless nonsense. Under the hood diskEraser is a Python-based program. All the implementation aims to use Python Standard Library and limit the use of external libraries. The only exception you will find is the use of Tkinter to create the graphical interface, that's all. As for using Unix vetted commands to perform erasures, we use subprocess module to interact with the system and execute the targeted commands. For example we use shred command to perform multipass erasure and cryptsetup for cryptographic erasure. DD is also used for some data filling. shred cryptsetup DD On custom system, whether it is live mode or installer version, the program is launched at system boot in GUI mode fullscreen. You can also use the terminal to run the CLI version. ISOs are created using Debian Live to include all required packages and make some configurations such as keyboard setup and program launching at system boot. Debian Live Disks details are its unique identifier, size, type (HDD or SSD) and if it's the disk where system is running. In a Linux-like philosophy I let people have the ability to delete the disk where the program is running from. An additional warning is provided to ensure you know what you are doing and a specific display is set to avoid mistakes. If you can delete your bootloader, you can shred your system (but knowing you’re messing up thanks to the warnings). HOWEVER an existing version turn off this ability to delete running disk by disabling the associated button. It still lists the drive and its ID but user cannot select it for erasure. During program execution every process is logged on both screen and log file.

Three Ways to Use It (Depending on Your Tech-Savviness Level) 1. The "I Know What I'm Doing" Method If you've ever casually mentioned "Python" (not the snake) in conversation: Download from GitHub (link is above) Type some impressive-looking commands Feel superior about your technical prowess Download from GitHub (link is above) Type some impressive-looking commands Feel superior about your technical prowess 2. The "I'm Comfortable with Computers" Method If you can find the terminal/command prompt but prefer not to hang out there: Set it up once with some copy-paste magic commands from github repo Type "de" inside a terminal whenever you need it Tell friends you "used the command line" and watch them nod respectfully Set it up once with some copy-paste magic commands from github repo Type "de" inside a terminal whenever you need it Tell friends you "used the command line" and watch them nod respectfully 3. The "Just Make It Work" Method If your tech support strategy usually involves calling a younger relative: Download the iso file from GitHub link Follow the instructions to put it on a USB stick Restart your computer with this USB stick plugged in and run live mode Click pretty buttons until your data is safely obliterated Download the iso file from GitHub link Follow the instructions to put it on a USB stick Restart your computer with this USB stick plugged in and run live mode Click pretty buttons until your data is safely obliterated You can also decide to run the ISO from a virtual machine to ensure to delete passed devices. Note that installer version from ISO install diskEraser as an app available from menu selection on a new Debian Bookworm system Important Notes (How Not to Ruin Your Life…) This Is Permanent: Unlike your commitment to that gym membership, there's no going back Backup Your Stuff First: Unless those vacation photos from 2016 spark neither joy nor legal evidence Different Drives Need Different Treatment: The tool is smart enough to know what it's dealing with, even if you don't This Is Permanent: Unlike your commitment to that gym membership, there's no going back This Is Permanent Backup Your Stuff First: Unless those vacation photos from 2016 spark neither joy nor legal evidence Backup Your Stuff First Different Drives Need Different Treatment: The tool is smart enough to know what it's dealing with, even if you don't Different Drives Need Different Treatment Two Ways to Interact (Choose Your Fighter) Graphical Interface For those who believe computers should be helpful, not hostile: See a nice list of drives with actual human-readable labels Click some buttons Watch a progress bar—the universal symbol for "something is happening" See a nice list of drives with actual human-readable labels Click some buttons Watch a progress bar—the universal symbol for "something is happening" Command Line Mode For people who want others to walk by and think "wow, they must be hacking something": Type mysterious text commands Watch text scroll by really fast Feel like you're in a 90s hacker movie Type mysterious text commands Watch text scroll by really fast Feel like you're in a 90s hacker movie Why diskEraser Is Better Than Expensive Alternatives Commercial data erasure tools often cost more than the device you're erasing. They're like paying someone $300 to clean a $50 coffee maker. diskEraser is: Free: As in "free beer," not as in "free advice that you didn't ask for" Open Source: Smelly geeks have examined every line of code, so you don't have to.
