Simply erasing a USB drive in Disk Utility will automatically format it too.Because there are different types of formats for different purposes, its good to know the differences before accepting the default settings.
If you are concerned about privacy, for example, you can format the drive with encryption and a password. Disk Utility can also partition a USB drive, creating two or more virtual drives from the same disk. If there are any files on the drive you need to keep, copy them to your Mac computer. Launch Disk Utility, located in the Utilities folder inside the Application folder in Finder. If you want to protect the disk with a password, select the Mac OS Extended (Case-sensitive, Journaled, Encrypted) format. ![]() For example, Doc.txt and doc.txt, are recognized as two different files. The journaled format protects the integrity of hierarchical file systems. Apple recommends using MS-DOS (FAT) for disks 32GB or smaller and ExFAT for larger disks. It takes only a second or two to erase a 32GB disk, but its not very secure. Formatting A Usb Drive Software Could StillAnyone with the right recovery software could still find the data. If data privacy is a concern, drag the slider to the right to use the Most Secure option. The two settings between Fastest and Most Secure balance security with speed. If you selected an encrypted format, enter a password and verify your password in the text fields. Each time you access the drive, you will be prompted for that password, although Keychain will offer to remember it for you when using it on your Mac. Type a hint to help yourself remember the password and click Erase. Click the Partition tab, if you want to use more than one partition in the drive. A drive with two partitions, for example can have one partitioned in ExFAT and another in a Mac OS Extended format, so you can use the same drive on a Mac and a Windows computer. Encryption is not an option when you partition a USB flash drive. ![]()
