> Try another brand of CD-R or CD-RW media.

> Power Calibration Errors can occur when OPC or ROPC tests for the

> Although the Firmware of CD Burners is physically burned onto a chip

> Power Consumption

> A device such as a CD Burners can have different problems if there is
> a power consumption issue with the system and the Power Calibration
> Error is just one of those problems. If using either an internal or

> check all cables for any faults and if possible test with a 2nd Data
> Cable. It is also advisable to disconnect the power connection for
> the CD Burner and test with a spare connector.
