If you accept a solid-state drive, start with encryption

If yous purchased your computer in the past few years, it probably has a solid-land drive. SSDs are faster than older, mechanical difficult drives and use wink retentivity instead of magnetic platters. Only the downside of the technology is that securely deleting files from an SSD is very hard. SSDs use a technique chosen wear leveling to prolong life, but a side consequence of this procedure is that data can remain on a drive even after you've erased it. Instead of using special software to erase an SSD'southward contents, you're better off encrypting the bulldoze, which employs a mathematical process to muddle up the information using a passkey that merely yous have. Without the key, files on the drive look like gibberish—even if someone succeeds in recovering files, that person still won't be able to open up them.

The good news: Encrypting your storage bulldoze is simple. This is something we recommend doing for every computer with an SSD, even if you're non selling it. You tin also encrypt mechanical difficult drives for the same reason, but the process takes a specially long fourth dimension, and it's easier to do a adept-enough job of removing data on mechanical drives.

Chromebooks usually use solid-state storage, simply Google enables encryption by default, then if yous're resetting a Chromebook, y'all can skip this department.

Windows

If you have a Windows estimator, encrypting your storage drive can exist a little tricky and depends on which version of Windows your estimator has and what components you take installed.

1. Open Settings > Update & Security. Look for Device Encryption on the left sidebar. If Device encryption isn't an choice on this screen, information technology's not available. If it's not showing up, too try searching for "device encryption" in the search bar, every bit in our feel information technology may show up there.
2. If Device encryption is turned off, turn information technology on.

1. Open Settings > Privacy & Security > Device Encryption.
2. If Device encryption is turned off, turn information technology on (BitLocker may be an option here, in which example you tin enable it and skip the steps).

If device encryption isn't an option, BitLocker may be, provided you take a copy of Windows 10 (or 11) Pro, Teaching, or Enterprise. In Windows 11, the BitLocker toggle is on the higher up folio in Settings, just in Windows 10 you'll demand to look elsewhere:

1. In the search box in the taskbar, type "Manage BitLocker" and so select it from the consequence.
2. Click Plough on BitLocker and follow the instructions.

If you're having trouble finding device encryption for your device, the Windows support articles may provide more information. BitLocker can also encrypt external drives, including SD cards and flash drives, which is a more than secure mode to delete files on such drives earlier formatting.

If BitLocker isn't an option, you'll need to turn to third-party software. We like VeraCrypt, merely keep in heed that its encryption procedure is more complicated than BitLocker'due south. Some SSD manufacturers may also provide software for securely erasing their SSDs, though we haven't tested whatever of those utilities.

Mac

Macs take had the same gratuitous encryption tool—chosen FileVault 2—since 2011, and the process is the aforementioned in every version of macOS:

Wipe and reset your computer

This is your final chance to recollect any files, so check i more time before yous go along.

Once you enable encryption on the SSD, or if your figurer has a mechanical difficult drive, all that'due south left is to format the storage drive and reset the operating system. When you do this, y'all have two options: to keep your files (which is useful if your figurer is running dull or has other issues) or to remove everything, which deletes all your files stored on the computer and reinstalls the operating arrangement. If your computer has an SSD and information technology's encrypted, this step isn't necessary if you're recycling the reckoner, but information technology is a good do.

5. Click Security Options. If you encrypted the storage drive, yous can go out this at the default option, simply if yous're formatting a mechanical hard drive, y'all should move it up to at least the second well-nigh secure tier, "3-pass secure erase."

In one case Deejay Utility finishes erasing everything, you lot tin turn off the computer. Or you can head back to the Utilities menu and select Install macOS if you lot desire to first the procedure for the next owner, simply that isn't required.
