In a world where locating data can be just as challenging as removing it, cryptographic erasure seeks to secure data by encrypting it, and then. Ensure that the data on your old drives is safe from prying eyes with this simple guide to securely wiping your hard drives. To use the system, reprovision the server. All data on impacted storage drives and persistent memory is erased and is not recoverable. All RAID settings, disk. BTC PREDICTIONS THIS WEEK

Nevertheless, we have used all of these methods successfully in the past. If you need to delete only specific files and folders rather than entire drives, the open-source Eraser is the tool for you. From there, a window pops up with the task and time-scheduling options. Click Add Data to select the files to wipe and choose an erasure method. I usually go with the DoD three-pass option. An Eraser option also appears when you 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 securely wipe specific files or sectors of your hard drive on a regular basis. Did you think using Erase was simple? Again, we suggest at least three. Be sure to select your operating system when downloading the utility; Windows 10 users can choose the Windows 8 option.

A note on whole-disk wiping software: Wiping entire drives requires slightly more complicated solutions than the easy-to-use apps mentioned previously. Once DBAN is up and running in all its blue-and-white glory, you simply select which disk to wipe, and press the M key on your keyboard to select an erasure method. Press F10 to start the wipe once everything looks good.

Depending on the method you choose and the size of the disk, erasing the data can take hours or even days. Bring a sandwich and your phone, or better yet, walk away and do something else while DBAN does its magic. 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.

The easier option is the go-to third-party utility, Parted Magic. This, however, is where we run into a paywall. You can also optionally put a couple of holes in the circuit board on the other side for good measure. Now, you apply brute force. Ideally, you want to put a nail through the platters of the drive, going all the way through it's actually not as hard as it sounds. Again, aim for the spot marked by the red X, and optionally the green stars for a more complete job.

This is a very effective method of destroying drives, and it's also a lot of fun, not to mention a great way to relieve stress! With solid-state drives, things can get very complicated, and I could write reams about TRIM commands and garbage collection, and so on. The problem is things get convoluted, which is when mistakes happen and your precious baby pictures or work project gets deleted.

With that in mind, I'm going to keep things simple. One way to erase SSDs is to use the manufacturer's utilities. Here are some links to get you started. One of the easiest ways is to encrypt the entire drive with a complex passphrase. On Windows, you can use something like VeraCrypt. On Mac, you can use the built-in FileVault utility, and you're done. No passphrase, no data. You can then format the drive, from which point it should be sterile and ready to accept a reload of the data.

If the drive is dead, or you just want to get rid of it in a hurry and don't want a functioning drive at the end of it, then you can take a hammer to the SSD or flash drive. One thing to bear in mind is that the data in SSDs is held on small flash storage chips rather than large platters, and to securely erase the data, you need to smash the chips.

Usually this means taking the cover off the drive before you start swinging. If you're not sure which are the flash storage chips, just drive a nail through all the large chips to be on the safe side.

Rapid encryption in BitLocker directly addresses the security needs of enterprises while offering significantly improved performance. In Windows Server , Windows 8, or later, Encrypted Hard Drives offload the cryptographic operations to the drive controller for much greater efficiency. When the operating system identifies an Encrypted Hard Drive, it activates the security mode.

This activation lets the drive controller generate a media key for every volume that the host computer creates. This media key, which is never exposed outside the disk, is used to rapidly encrypt or decrypt every byte of data that is sent or received from the disk. Configuration of Encrypted Hard Drives as startup drives is done using the same methods as standard hard drives. These methods include:. There are three related Group Policy settings that help you manage how BitLocker uses hardware-based encryption and which encryption algorithms to use.

If these settings aren't configured or disabled on systems that are equipped with encrypted drives, BitLocker uses software-based encryption:. Encrypted Hard Drives utilize two encryption keys on the device to control the locking and unlocking of data on the drive.

The Data Encryption Key is the key used to encrypt all of the data on the drive. The drive generates the DEK and it never leaves the device. It's stored in an encrypted format at a random location on the drive. The Authentication Key is the key used to unlock data on the drive. A hash of the key is stored on drive and requires confirmation to decrypt the DEK. When a computer with an Encrypted Hard Drive is in a powered off state, the drive locks automatically.

As a computer powers on, the device remains in a locked state and is only unlocked after the Authentication Key decrypts the Data Encryption Key. Once the Authentication Key decrypts the Data Encryption Key, read-write operations can take place on the device. When writing data to the drive, it passes through an encryption engine before the write operation completes. Likewise, reading data from the drive requires the encryption engine to decrypt the data before passing that data back to the user.

In the event that the DEK needs to be changed or erased, the data on the drive doesn't need to be re-encrypted. After the restart, Windows will encrypt the drive. In case you want to encrypt a removable drive, Windows will not require a restart and will encrypt immediately.

For an encrypted system drive, Windows will ask you to unlock the drive — via password , key, or connecting your USB. To unlock an encrypted removable drive, simply type in the password , when you connect it to your PC. You can install it on every Microsoft OS from Windows onward. DiskCryptor is also lightweight, which helps avoid a noticeable impact on your system performance.

The software is specialized in encrypting sectors. This means that full disk encryption could take a while. Reviews suggest that the tool is awesome for encrypting drives and smaller parts of your system. Decryption will be considerably slower though, so you can go grab a cup of tea and a good book. You can use it on Windows, Mac and Linux operating systems.

The tool is constantly being updated, so improvements in terms of functionality and security keep coming up. VeraCrypt is very flexible and can be used for both full disk encryption and just encrypting a single file. Both tools are quite similar and the truth is you can use them combined to achieve the maximum efficiency.

The biggest difference between them is actually who can use them. VeraCrypt can run on practically every operating system. Power-users may prefer to use VeraCrypt, because it uses several encryption algorithms and is open-source - which means anyone can apply changes to it. The process is similar to all other types of encryption. Stick with the default settings, unless you have a good reason to change them. Do backup anything important before beginning to format. In a nutshell, both software are excellent and will serve you well.

What about yourself, as a Mac user, you ask? Well, FileVault already exists in Mac environment. You have the option to enable it to start preventing unauthorized access. Doing so is very easy, too. The next step is to choose how you want to be able to unlock your disk and reset your password.

The encryption occurs in the background as you use your Mac, and only while your Mac is awake and plugged into AC power. Any new files that you create are then automatically encrypted as they are saved to your startup disk. After the process is done, you will need to restart your Mac. But let me share a secret with you. You can actually go without any encryption software. What you need is a. It does the job, all while hiding in the shadows.

It has a circuit built into the disk drive controller chip, so all data is encrypted and decrypted to the magnetic media automatically. The encryption is absolutely invisible to the user. You just give the drive a password and from there on you are best buddies.

What are best friends for, after all? SED are secure, reliable and easy to use — go for it. Securing your external drives is essential. The USB is a small and convenient way to carry your data everywhere. That also makes it easy to be stolen or lost. Luckily, you can buy a flash drive with integrated encryption software. These drives use a physical pin pad and often come with features like automatic overwrites, in case you enter an incorrect pin too many times.

This method is not immune to failure, however. Besides being much cheaper or even free, software tools are just as effective as the hardware solution. The only major flaw is the time it takes to encrypt your files. It also requires a bit more tinkering, but no worries. The process is pretty much the same as with USB drive encryption.
