Recording an Additional ISO 9660 Session
This section describes adding a session to a CD that contains a previous session. For more information on this and other multisession options, see Working with the Select ISO 9660 Window.
To ensure that data from the previous sessions is still accessible
1In the Data tab, click the Disc Settings button (or the disc title).
The Disc Settings drawer opens.
2 In the Disc Settings drawer, click Advanced, then select the ISO 9660 option.
3 Drag any data to the ISO 9660 content area.
4 Click Select.
The Select ISO 9660 window appears.
5 In the Select ISO 9660 window, click the Settings tab.
6 Ensure that the format CD-ROM XA is selected, and select the same Naming option that you used in the previous session.
7 Click Done.
The size of the selected data appears in the Data content area.
8 Insert into your recorder the ISO 9660 disc you want to add data to.
To verify that the inserted CD is the correct one, choose Recorder > Disc Info.
9 In the Disc Settings drawer, select the ISO 9660 option again (if it changed).
The Multisession Options dialog appears.
10 In the Multisession Options dialog, select an options:
• If you don't want previous sessions visible when inserting the CD, choose Ignore Existing Sessions. Choosing this option produces a CD that contains ONLY the data from the new session. (All old data will be inaccessible.) This is the best option when you only care about the data recorded in the current session and don't want the older sessions to clutter your view of the CD.
• Note: Only use this option if you are sure you no longer need older sessions.
• To make all sessions visible when you insert the CD, choose Append to "[name of last session]." The new session is added to the existing ones already on the CD. This is a good choice when you want to preserve an archive, and each session contains data you need.
• The Append To option results in a CD that has the name of the new session as its volume name or label and has both the new data and the old data together in the "top" level of the directory structure.
• It is also possible to delete folders selectively from the structure.
• For example, if you no longer needed a particular folder, you could create a new folder in the ISO dialog, give it the same name as the folder you no longer need, and then define it as invisible. Afterwards, you could add any new data you may want and then record a session. Toast will add the new data to the structure, and the folder you marked would no longer be invisible. (see Changing Names and Visibility).
• For backups recording only the data that has changed since the previous session, choose Incremental Backup.
11 Click OK.
12 Choose Recorder > Recorder Settings (or click the green Recorder Options button, and choose Recorder Settings).
The Recorder Settings dialog appears.
13 In the Recorder Settings dialog, click the Advanced tab, and then select the option you want:
• If you want to add data to this disc later, uncheck Close Disc. (If the resulting CD would be nearly full, or you forgot to select CD-ROM XA, this option is disabled.)
• To close the disc so that no further data can be added later, select the Close Disc check box.
14 Click OK.
15 Click the red Record button.
16 When prompted, insert a disc into the recorder.
Toast displays a progress bar as it burns your data to disc. A message appears indicating that recording is complete.
