Power Calibration Error when copying to DVD

  sheila.weston 11:30 17 Dec 2004

Can anyone suggest how I can correct a 'Power Calibration Error' (according to the log file) when I try copying Data files to DVD. I can copy to a CD without any problem. I was using Nero 5, but have downloaded a trial copy of Nero 6 from ZDnet and the same thing happens. My drive is a new Sony Dual Drive DVD RW DW-D22A.

try different media - I used to get this error when using certain kinds of disk - there was nothing wrong with the writer (not the same one as yours)

if this does not cure it suggest trying something different from nero to burn with

I was at PCWorld yesterday, thinking about getting some different discs. The advice counter checked the disk I was using and said that it should be OK to use so I didn't get any more! Fiddlesticks!

Yes, I *will* get some different ones at the next visit. Meanwhile I have shown the log printout to a friendly local computer engineer and he thinks that the drive is at fault, so I have made a tentative appointment for a check and possible replacement in January. It is just too much hassle to send it back to Mesh. But I'll try different discs before that.

Yes, I tried downloading a trial VSO and that didn't work either. That log said something like 'dirty burner', but it is meant to be NEW. I don't want to waste money on a ?'drive cleaner' as it really shouldn't be needed. Better to cut my costs and get the experts in.

Many thanks for those two links, Rayuk. They are most useful.

Georgemac - I have managed to exchange a Bulkpaq DVD+R disk for a Bulkpaq 4 x speed DVD-R disk which WORKED. So you were quite right - I should have done this ages ago!

ALSO - Someone found a FAQ on the Nero website, which explains more, so I'll mark this thread as 'resolved'.:
9. I get a 'Power calibration error' or 'Calibration area (almost) full' error message. Why?
Power Calibration is controlled by the recorder.
Before any write operation, all recorders must do a 15 step power test to determine the optimum power for writing to the CD; this is called "Optimum Power Calibration"(OPC). During the write, it continues to do this test to get the best write throughout the whole CD; this is called "Running Optimum Power Calibration" (ROPC).
This whole process is controlled by the recorder, though initiated by programs such as Nero. There is an area on the inner part of the CD for the test and test data info to be stored. You can use this area up to 999 times.
If you receive the "Power calibration error" or "Power calibration area is (amost) full" error message, the cause will be either poor media, poor power, or a defective recorder.
Please try the following solutions:
Update the firmware of your recorder. Please check the manufacturer's website for the latest version.
Try another brand of CD-R or CD-RW media.
Try different power connectors, and for recorders, do not share power with other devices. It needs its own power connector. If the error occurs with an external recorder, the power source in the chassis could be the cause. As a test, try to take the recorder out of the external chassis and connect it internal.
Try different configurations, such as taking the CD-ROM to the primary IDE bus as slave and have only the recorder connected to the secondary IDE bus as master.
Send the recorder in for service.
