DMA will not stay enabled

Reasons why DMA will not stay enabled after restarting your computer

1.The device (hard drive, HP CD drive, HP DVD drive, CD-ROM drive) does not support DMA.

2.DMA is not available on your computer.

3.DMA has not been enabled in the computer's Basic Input/Output System (BIOS).

Refer to your computer's manufacturer for more information about using DMA on your system.

Software Errors

HP RecordNow reported it was unable to read fast enough

When HP RecordNow creates a CD, it does so in a single, continuous operation. This operation requires that the computer's hardware and software transfer data from the source device to the HP drive fast enough to keep the HP drive's laser turned on at all times. If the HP drive becomes "starved" for data, the laser will turn off, and the recording session will fail. There can be many different causes of this error.

This error is more likely when making second-generation copies, when using a slow or unreliable CD-ROM as the source drive, or when using faster write speeds (10X or 12X) especially when the blank media is not rated for higher speeds.

Other problems occurred after enabling DMA

If you enabled DMA and your system locks when accessing the HP drive or you start to have other system problems, disable DMA as a possible solution.

If you are prompted to "retry" following a failed CD recording, first, try the following:

1.Clean your source CD.

2.Use your HP drive as your source drive.
