Lite-On eHAU424 External DVD Writer
Apr 12th, 2010 | By NivedhThe Lite-On eHAU424 comes in a red box. There’s a picture of the drive on the front. Curiously, there is no identifying information other than “24X External DVD/CD Writer”. The eHAU424 is actually the internal model number.

On the sides, we have the specifications in English and Spanish. The read and write speeds for everything are listed.

Turning to the back, we can see all the special features. Let’s take a closer look at the features and specifications before continuing to open the package.
