Options for securing external storage in OS X

USBDriveIconXThe default approach for storing files on drives other than your boot drive is to get an external storage device and then copy your files to it; however, by doing so you leave open the possibility of someone getting your drive and accessing your data.

How to manage iNode files in the “lost+found” directory

HardDriveIconXIf you open your Mac’s boot drive, you may find a folder called “lost+found” next to the System, Applications, Users, and other system directories at the top level of theĀ drive.

Until now TRIM support in OS X was reserved for Apple-supplied hard drives, but with the release of OS X 10.10.4, Apple has included a tool that allows for TRIM on third-party SSD devices.
