4. Helpful Technical Information

When writing DVD±R/RW and CD-R/RW discs,

you will have the option to assign the disc a particular

file format (the way in which a computer names and or-

ganizes files for storage and to manage data exchange).

There are essentially three file system formats to be con-

cerned with when using a LaCie DVD/CD Drive:

Universal Disk Format (UDF)

ISO 9660

Mac OS Extended (also known as HFS+)

UDF -

This specification, developed by Optical

Storage Technologies Association, is the predominant

file system that allows compatibility across various Blu-

ray, DVD and CD applications, hardware platforms and

computer operating systems.

ISO 9660 -

This is the standard file system which

allows media to be read on a Mac, PC or other ma-

jor computer platform. Published by the International

Organization of Standardization, this standard defines

a file system for DVD-ROM and CDs. It supports

Microsoft Windows, Mac OS and operating systems

that follow the Unix specification, but doesn’t support

custom features of Mac file systems such as long file

names or icon options. Microsoft created an extension

to the format, called Joliet, which allows for Unicode

file character names and file names up to 64 characters

in length (twice as many as the ISO 9660 Level 2 and

3 specifications).

Mac OS Extended -

Also known as HFS+, this is

the file system used by Macintosh. If you will be using

your disc only on Macs, this is the preferred file format.

Hybrid discs (Mac & PC) -

Mac users can also

choose to create hybrid discs which contain two par-

titions: one to be viewed by Mac users, one by Win-

dows users. Toast 7 Titanium does allow this file system

choice.
