2017 BEST FORMAT FOR FLASH DRIVE ON MAC INSTALL

Install and run it, then click “Create Volume” and then “Encrypt a non-system partition/drive.” Choose “Standard VeraCrypt volume,” click “Select Device” and then “Removable Disk”-where you should only see one drive selected, assuming you unplugged other external drives first.Īfter encrypting the drive, reformat it (right-click it on the Windows desktop and choose “Format…”), then repeat the encryption step. (Dear Microsoft: Home users care about privacy too.) If you run a home version of Windows, you’ll have to use the open-source VeraCrypt app for this task. Things are a little more complicated in Windows, thanks to Microsoft not supporting disk encryption in the Home editions of Windows.

Finally, erase it in Disk Utility again to leave it free for the next user. Either way, you’d then use Disk Utility to erase the drive, then repeat the encryption step. If you don’t see that prompt, it may be because the drive was formatted for use with Windows systems open Disk Utility, select that drive, click “erase” and go with the default settings. On a Mac, right-click the drive you want to wipe and select “Encrypt” and then follow its prompts. Both Cobb and Joseph Lorenzo Hall, chief technologist for the Center for Democracy & Technology, endorsed that strategy. The other reason to avoid this method is that it can be painfully slow on large drives-a 2017-vintage Windows laptop needed 22 minutes to do a triple overwrite of a 4 GB flash drive.Įncrypting the entire drive to make its contents unreadable without a key-then erasing it and encrypting it again-takes much less time to make your data disappear. Mike Cobb, director of engineering at the data-recovery firm DriveSavers, noted that your flash drive’s vendor may provide an app with simpler secure-erase tools, pointing to ones from Intel, SanDisk and Samsung. On a Mac, open the Disk Utility app, select the drive, click “Erase,” then click “Security Options…” and move the slider control to the third, “3-pass secure erase” option. On a PC, open the command prompt from the Start Menu and type “format e: /p:3,” (if “e” isn’t the letter for the flash drive, change that accordingly).

You can still use the method of dumping random data three times in a row on an entire flash drive, although tools to do that are less than obvious in both Windows 10 and macOS High Sierra. It didn’t want people thinking they could scrub a file from a drive when the attempt might not succeed on a flash drive. That’s why Apple removed the “Secure Empty Trash” command from the macOS Finder in 2015’s El Capitan version. If you’re not sure if your external drive is flash or not, seeing if it fits cleanly into a shirt pocket should is your easiest cue, followed by its complete absence of noise.īut when it’s time to wipe a drive so you can sell or donate it to somebody else, flash drives impose complications that hard drives don’t: Because they automatically move bits of data to less-used areas of the drive to extend longevity, the traditional secure-erase technique of overwriting files with random data may not clear out all of it.

Flash drives work faster and, since they store data in solid-state memory instead of on spinning magnetic platters, they also work longer.Īnd they’re a lot smaller. The computer industry’s migration from hard drives to flash drives has mostly brought good things. However, the file system is not supported by many older systems.When it's time to donate or ditch an old flash-memory drive that stored sensitive information, deleting those files isn't enough. The safest way to wipe the slate clean is actually to encrypt it - and that's not as hard as it sounds. In theory, data capacity of up to 2 TB is possible, but Microsoft has limited the partition size in newer systems to 32 GB in order to promote the modern NFTS format.ĮxFAT is a further development of FAT that in principle offers unattainable storage and data capacity. The maximum data size is limited to 4 GB in the latest version FAT32. It is not supported by many applications.įAT is a file system developed by Microsoft that is also supported by Linux and macOS.

Mac OS Extended (Journaled) with the addition that the file system can differentiate between upper and lower case (e.g. HFS+ or Mac OS Extended (case-sensitive and journaled) Windows/Linux devices are only able to read but not write on USB sticks in this format. A file system developed by Apple that is particularly suited to data media with large memory capacity.
