It will format the external drive and erase all of its contents. Backup your data and all contents before proceeding, and do not lose the set password.

  • Let Disk Utility run; when finished, the drive partition will show up on the desktop. The drive will be accessible now without a password allowing files to be transferred over. Eject the disk when finished to require a password upon further mounting and usage.

Clicking on the Remembering password in the keychain will allow the drive to be mounted on a Mac without entering that Mac’s password. But it will still require a password to be used on another Mac. For Maximum security, it’s best to leave that option unchecked.
