I Dont Want the Us Government to Review My Hard Drive
The siren has sung and you've finally succumbed to her call: Y'all're the proud possessor of a shiny new PC, a faster SSD, or a bigger hard bulldoze. It'south time to sell or donate your former gear and get-go playing with your new toys, correct? Not and so fast. First you need to deeply erase the data off your onetime hard drives so you don't become a victim of place theft.
Simply deleting the data off your hard bulldoze doesn't erase information technology as you might wait. Instead, NTFS (the file system used by Windows PCs) just hides the data from immediate view, leaving information technology to be overwritten when a new file takes upwardly residence on the drive. That'south a workable scenario for everyday use, but information technology could spell disaster when it's time to part with an old machine.
To truly destroy the data on your storage device you need to take more drastic (and time-consuming) measures to overwrite your bulldoze space with ones and zeroes. That's where this guide comes in.
Unlike applied science and scenarios call for dissimilar tools. We'll place the best secure-erasing utility for every job, no thing what type of drive you're using—even USB flash drives. If you want to erase only specific files, we'll prove you how to do that, too. All-time of all, almost every solution discussed here is gratis.
Earlier you brainstorm
William Warby (CC BY 2.0) Dorsum upwardly your data! Once these programs go to work, you can't get back for a forgotten file. This is a one-way street to information oblivion. Also if yous're erasing the bulldoze on a laptop, be sure to plug the notebook in earlier y'all get-go. If the battery gets spent and the ability goes out in the center of a deejay wipe information technology could spell disaster for the drive.
With that out of the fashion allow's talk terminology. Drive-wipe utilities let you lot specify how many "passes" the software makes. Each pass signifies a complete overwrite of the information. A utility that makes three passes overwrites your drive with ones and zeroes iii split times. The more times you overwrite your data, the less likely it is to be recovered. Some utilities support "Gutmann"-level protection with 35 passes, merely three passes is enough for the U.S. Department of Defense force's "Brusque" specification and for numerous militaries around the globe.
If you practice choose to erase your information with any of these methods, you practice so at your ain risk—which is why nosotros suggest making a backup before y'all begin. Withal, we have used all of these methods successfully in the past.
Securely erase specific files with Eraser
If you need to delete but specific files and folders rather than entire drives, the open-source Eraser is the tool for you. Just boot up the program, click the arrow adjacent to the 'Erase Schedule' option at the top of the screen, and selectNew task. From there, a window pops up with the job and time-scheduling options. ClickAdd Data to select the files to wipe and choose an erasure method. (I unremarkably get with the DoD three-pass option.)
IDG Eraser 6.two for Windows.
An Eraser option also appears when you lot right-click on a file in Windows Explorer, allowing you to permanently delete files quickly and easily.
Eraser has a ton of advanced scheduling and file options if you want to deeply wipe specific files or sectors of your hard drive on a regular basis. Be careful while yous tinker with the effectively settings, though—you don't want to accidentally wipe something of import. Also note that Eraser is meant for mechanical hard drives, as the wear-leveling algorithms in solid-states drives (SSDs) negate the utility'due south ability to securely wipe information.
Securely erase your USB flash bulldoze
Did you call up using Erase was simple? Roadkil's Disk Wipe is even easier, and it works just fine on USB flash drives besides as traditional hard drives. But download, unzip, and boot the itty-bitty application, and so select a bulldoze and type in the number of passes you'd like the program to make. (Once again, we suggest at least iii.)
IDG RoadKil's Disk Wipe 1.2 for Windows.
Choose to either wipe the deejay or fill up it with junk data, click Erase, and you lot're washed. Roadkil's Disk Wipe hasn't been updated in years, but information technology merely works. Exist sure to select your operating system when downloading the utility; Windows 10 users can choose the Windows viii choice.
Securely erase a mechanical hard drive with DBAN
A notation on whole-disk wiping software:Wiping entire drives requires slightly more complicated solutions than the easy-to-use apps mentioned previously. Since you'll exist deleting the information from the drive that likely holds your PC'south operating system, nearly tools that wipe whole drives crave you to motion the plan to a flash drive or create a bootable thumb bulldoze from an .iso file.
To ensure that things run smoothly, you should likewise dive into your BIOS settings and make sure that your drives are gear up to IDE mode.
Download DBAN—a time-tested choice for erasing HDDs that's loved by geeks around the world despite the fact that information technology hasn't been updated in years. One time you've downloaded it and created a bootable USB, insert the drive into your PC, and tell your computer to boot from the USB bulldoze rather than your hard bulldoze. If you're hoping to erase a RAID-enabled hard drive, yous'll need to disassemble the RAID volume and set each disk to JBOD manner before y'all offset, besides.
IDG Once DBAN is up and running in all its blue-and-white celebrity, y'all but select which disk to wipe, and press theM key on your keyboard to select an erasure method. The iii-pass "DoD Short" is (notwithstanding) my preferred method, though more-robust options are bachelor. PressF10 to outset the wipe in one case everything looks proficient. Depending on the method you choose and the size of the disk, erasing the data can have hours or even days. Bring a sandwich and your phone, or better yet, walk away and do something else while DBAN does its magic.
Deeply erase a hybrid drive or SSD with Secure Erase or Parted Magic
Wiping information off of an SSD is a little different than erasing data from a HDD thanks to the wearable-leveling algorithms used to write data evenly to an SSD. To deeply erase all the information on an SSD, y'all employ a command—called ATA Secure Erase or NVMe Secure Erase, appropriately enough—that's built into the firmware of modern SATA and NVMe SSDs and older PATA/IDE drives.
Near modern SSDs ship with the ability to initiate secure erase, or the manufacturer provides a proprietary tool such as Crucial, Samsung, SanDisk, Seagate and Western Digital. If your drive maker doesn't offering a secure erase solution or the manufacturer solution doesn't handle reformatting boot drives you take two options. If the drive is removable, you can plop it into an external drive case, and connect it to another PC via USB to wipe it from there.
Parted Magic The easier option is the go-to tertiary-party utility, Parted Magic. This, however, is where we run into a paywall. At this writing, Parted Magic costs $11 for a copy of the software, or $39 for a lifetime subscription, significant you get continuous updates. The utility is awesome and easily worth the price.
After payment, download the Parted Magic .iso and create a bootable thumb drive. Kicking the drive, and you lot'll get to a Windows-like desktop screen. On the desktop at that place's an Erase Disk launcher. Now it's but a matter of post-obit the instructions. Parted Magic's help pages as well provide instructions on what to do for both regular SSDs and NVMe drives.
If Parted Magic warns that your bulldoze is frozen, put your estimator to sleep equally suggested, turn it back on, and rerun the utility. If y'all're asked whether you want to run an Enhanced Secure Erase, clickNo; you'll want to stick to the tried-and-true standard version.
