Chapter 13. Troubleshooting Recorder Pro... > Eliminating Buffer Underrun Errors

Eliminating Buffer Underrun Errors

If your recorder doesn't support burn-proof recording, even the fastest computer may fall victim to the dreaded buffer underrun error; as you learned in earlier chapters, this error results when your computer can't transfer data to the recorder at the necessary rate to ensure a successful recording. The older and slower your computer, the more likely it is that a disc will be ruined. Try these solutions:

  • Record from a disc image. Rather than recording a number of smaller files “on-the-fly” (which is far less efficient), try creating a disc image, then record from the image—this is much more efficient and requires less overhead, because the image is a single file.

  • Record at a slower speed. Although your system may not be able to support the highest speeds available with your recorder, you can always record at a slower speed—for example, if you can't record at 32x, try recording at 16x, instead.

  • Don't multitask while recording. Dedicate the entire resources of your computer to recording by shutting down all unnecessary applications (including those running on the Windows taskbar).

  • Defragment before recording. A defragmented drive transfers data significantly faster; I describe how to defragment a hard drive running Windows XP in the section titled “Defragmenting Your Hard Drive” in Chapter 3.

  • Use the fastest drive on your system. Whenever possible, choose the fastest drive on your system as the location for source data and temporary files created by your recording software.
