Procedures for creating Image files of Optical Volumes on the Mac

Before beginning, be sure that all source volume to be copied has been properly updated in the Synclavier by inserting into drive and selecting ‘Load Volume’ on the R-Page.

1.   From the Real-Time program (RTP), ‘break’ to the READY prompt. Use the OPVOLUME utility to check the amount of used space on each source volume. Record this information for later use.

2.   Quit Synclavier®PowerPC™ (S/PPC) and open the InterChange utility. Set Op0: Disk Image and click the SAVE SETUP button.

3.   Click on CREATE button next to Op0:. When the window opens enter the size you wish to make the Optical Image.


Note - The size should be at least 2% greater than the total space used on the source

media to be copied to it. More than one source volume can be copied to a single Optical

Image as long as the total size does not exceed  the Mac limit of 2 gigabytes per file.

You will now be prompted for a name and location to store the file following the standard Macintosh convention.

At this point you have created an Optical Image that from here on out will be treated

just as if it were a new blank optical platter.

4.   Quit the InterChange program and return to S/PPC. Break to READY prompt and use FORMCOPY to Format O0: This will take about 15 min./GByte.

5.   Once the format is complete, boot back into RTP and use the R-Page to Format (name) the new volume.  Be sure NOT to name it exactly the same as any other optical volume you have or indexing problems will occur.

6.   Quit S/PPC and return to InterChange once again. Set Op0: to the source drive and Op1: to the new optical image. Click on SAVE SETUP, Quit InterChange, and return to the RTP one last time.

7.   ‘Break’ to the READY prompt  and type OPCOPY. Check that the Source and Destination volumes are correct before pressing RETURN to begin the copy. The ‘I’ key can be used to alternate Source and Destination just as in FORMCOPY if needed.

8.   If copying more than one source volume to the same Optical Image file, insert the next volume and  repeat step 7.

9.   Once complete you can select an optical image as Op0: from InterChange and use it just as if it were an actual platter or simply as an archive.
