Hi, according to what I understand the unit works for some situations especially but you cannot visualize the content, in this case the problem that you one presents shows off to be Cd-DVD's unit that this trumping, if the equipment this one even in guarantee, you must come to an CAS or Center of Authorized Service, in order that they diagnose and replace the unit
Power Calibration error indicates that the drive hasn't been kept clean and is unable to guarantee a good write to disc... I recommend a wet and dry CD/DVD Cleaner disk with Alcohol on the wet side (Like Tape Head cleaner liquid) and let it dry for a minute then run the disc again... if it still happens the drive is on its way out.
A couple of possibilities:
With a known good DVD with files inserted into your Compaq CR-589, double click in your My Computer, double click in your CD/DVD.
1. If it opens and displays the content, then there is nothing wrong with your DVD but the auto start feature of your OS was disabled, enable auto start;
2. If in My Computer or in Device Manager, the DVD doesn't show up, then it can be hardware problem, IDE/power cable problem, bios did not recognize DVD device, replace if and as needed;
3. If the DVD is in My Computer but will not display the files or contents, possibly defective DVD, replace.
Hope this worksa out for you. Pls post again how things turn up. Good luck and kind regards.
The semaphore timeout period has expired refers to the fact that the driver is no longer communicating with the device and failed.
Each time a CD Burner is setup for a CD Burning session the burner hardware will perform a 15 step power test to determine the OPC for a Blank Media Disc, OPC meaning Optimum Power Calibration.
This test also takes place during the CD Burning process so the CD Burner can determine the best burn speed and method for the disc; this test is called 'Running Optimum Power Calibration'.
Although the test is performed by the hardware of the CD Burner, the device initializes the CD Burning Software for the test to take place. This is one reason why your software may report the "Power Calibration Error" or ?Calibration Error Full?.
With Power Calibration errors they can be caused by different factors and sometimes difficult to locate, especially if the errors are at random. Below are the known factors that will cause the Power Calibration Errors and how to check each factor, it is important that each point is considered if wanting to get to the bottom of the error.
Power Calibration Errors can occur when OPC or ROPC tests for the media disc so the condition of the disc, brand of disc and even the firmware for the CD Burner can be the cause for the errors occurring.
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 external CD Burner make sure to disconnect all other devices, except the hard drive and Burner, before attempting to burn a disc. Double 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.
If you have no trouble with other discs, use them and put to one side the lightscribe, other than that try the burner in another pc or with other burning software, as you can see it's quite ridiculous what problems burners can create.
