TOAST

Toast is CD Burning software for Macintosh first developed by Miles Software GmbH (Astarte), then around 1997 bought by Adaptec. Adaptec spun its disc burning software to a new name, Roxio in 2000. Later bought by Sonic.

File Information

 * Early versions of Toast software would save a disc image with no extension, as was common for Macintosh systems, but would add "•image" to the end.
 * Starting In Toast 5.1 (2002), the extension ".toast" was added, probably to be compatible with Mac OS X.
 * In Mac OS X, it seems .toast files can be renamed to .iso with full compatibility.
 * When saving an Audio CD to a disk image, Toast saves image to the Sound Designer II .sd2f format.

File Identification

 * Early •image & .toast files begin with the hex values "" which are an Apple Partiton Map. Later versions don't seem to have this header.
 * Most disc images and also the project files have the text string "TOAST ISO 9660 BUILDER COPYRIGHT (C) 1997 ADAPTEC, INC. - HAVE A NICE DAY" with the difference of date and ownership, ROXIO, SONIC is later versions.
