Will
creating data CDs from the hard drive help avoid Buffer Underrun
Errors in Toast on a Mac?
Creating data CDs from slower input devices, such as Zip drives,
Jaz drives, older CD-ROMS, or over a network, will often result
in Buffer Underrun errors on the Macintosh. To help insure a more
efficient writing session and to avoid the Buffer Underrun errors,
it is recommended that the files first be copied to the Macintosh
Hard Drive before writing the CD.
NOTE: There must be as much available Hard Drive space
as the original content required.
Steps:
File Selection:
1) Launch the Toast application.
2) Double-click on the Hard Drive icon on the desktop.
3) With the Hard Drive window open, select the files and folders
to put on the CD.
TIP: To select multiple tracks hold down the 'command'
key while selecting the tracks.
4) Drag the selected files to the top portion of the Toast window.
Toast will automatically select the appropriate format (audio,
Mac Files and Folders, etc).
TIP: For more information on supported formats, refer to
the Toast pdf format manual (i.e. 'Toast User Manual 3.5.pdf'
or 'Documentation.pdf') that is usually installed on the Hard
Drive in the Toast folder.
Removing Undesired Files:
1) To remove any undesired files or folders that have been selected
and moved to the top window of the Toast screen, click on the
<Data> button, locate the undesired files or folders and
highlight them.
2) Click the <Remove> button.
3) When finished removing files from the Toast window, click the
<Done> button.
Writing Data to CD:
1) Click the <Write CD> button once all the files to place
on the CD have been selected. The 'Start Writing Now' window will
appear.
2) The option is available to select the appropriate 'Write Speed'
from the drop-down list, though data CDs written from most Hard
Drives can be written at the maximum available speed.
NOTE: Check the 'Simulation Mode' box to test the function
of the computer system. 'Simulation Mode' actually verifies the
data transfer rates and functionality of the Yamaha drive. It
will not write data to the CD. It is only a ''practice run''.
NOTE: The option to select the 'Create Disc Image First'
is not necessary because the procedure above has been performed.
However, for future reference, the 'Create Disc Image First' box
can be checked if the CD is being burned from somewhere other
than the Hard Drive. A 'Disc Image' creates a copy of the information
on the Hard Drive first, then writes to the CD. This action will
help insure a successful burn. A Disc Image is not compressed,
therefore, there must be as much available Hard Drive space as
the original content required.
3) Click either the <Write Session> or the <Write Disc>
button to begin the writing process.
NOTE: The 'Write Session' option (if available) should
only be used when writing data (anything but audio) to the CD.
Writing a session allows data to be written to the CD until it's
full. Each session written will show up as a separate CD icon
on the desktop display, though all sessions will be written to
the same CD. 'Write CD', is different from 'Write Session' in
that when the <Write CD> button is clicked, it writes the
data to the CD, then locks the remaining space on the CD allowing
no other data or sessions to be added. This option is useful when
writing CDs for distribution.
