How do i sove disc error problems

I too have this problem with my Pioneer PD-X77M. It will not recognize the CD in the case & goes through all six saying NO Disc.

Read head damaged.

If a read head burns out or the alignment has changed, the laser is inoperative. If a CD/DVD was a copy or reproduced on a computer it too may not be read. If the medium works on other devices, then the players laser may be defective.

Have you solved this problem? I met the same problem. A clean CD doesn't work because I can't insert any CD.

Are the discs ones that you created (burned), someone else burned, or commercial discs? The message of disc not finalized usually appears when you put a CD or DVD from one unit into anther without closing (finalizing) the disc. The finalization step doesn't matter if the disc is being moved between computers with compatible OS versions (for example: XP through Windows 7). However, any other device will need this procedure completed.

Take the disc back to the unit (computer or other burner) where the disc was burned. If the computer uses Windows, put the disc in the optical drive. Open My Computer (Computer) depending on the OS by double left-clicking on the icon on the desktop. Right click on the optical drive and select Close Session.

If you created the CD on another machine, check the details for that device.

Note: you should double-check that the format that you burned to disc is compatible with this CD player. Not all models support MP3 files. On my own older CD player, I had to burn WAV files without gaps in a Disc At Once format to get the discs to play without skips.

I hope this helps.

(if the discs were commercial discs or have been finalized, I would expect a different error. In that case, I'd suspect a tracking problem and a "No Disc" error.)

The laser pickup unit [Optical Pickup Unit] is faulty. Bose uses a special type. You can't get it from open electronic spare part market. It is best to get this set repaired by the authorised service center for bose at your town.

From the description the new DVD driver is defective and should be returned if still under warranty. The only concern that I have is the replacement you got is identical to the original and that it is not a aftermarket product, because they don't have the same specifications as the original.

Is this the case with all CD's, or just one? Have you tried cleaning the CD?

Anything that creates finalized standard audio cd's will do (filenames= xxx.cda). On a PC that would usually mean copying the files from original CD's rather than 'ripping them, then 'burning' the project to a disc.

When you try to write data to an optical disc, you may experience any of the following symptoms:

* You receive various disc write error messages.
* You experience issues with the drive and the built-in recording feature of Windows XP.
* You experience issues with third-party programs that you use to write data to the disc.
* You cannot read the disc in all versions of Windows.
* You cannot read the disc, or some files on the disk, by using an MP3 player.
* When you add files or folders to a disc that already contains data, some files are lost.
* Recording files to the disc is inconsistent.
* The disc recording operation is consistently unsuccessful.

TROUBLESHOOTING

Troubleshooting specific errors
If you experience one of the following errors, follow the appropriate steps to resolve the error.

* There is no disc in the drive. Please insert a writable CD into drive.
This error can occur if the CD-R drive or CD-RW drive is not recognized as a recordable device. This error can also occur if the device driver has been corrupted. To resolve this issue, see Method 3 in the "General troubleshooting" section and Method 1 in the "Advanced troubleshooting" section.

* Drive not accessible, incorrect function
This error message typically occurs when you try to write to a CD-R or a CD-RW, and the Windows XP built-in disc recording feature does not recognize the CD drive as a recordable drive. This error message may also occur if specific third-party programs are installed. For more information about how to troubleshoot this error,

when you access the CD-ROM drive, the DVD-ROM drive, or the CD-RW drive
* Error Deleting File or Folder.
Cannot delete file name. Files on this CD-ROM drive are read-only. You cannot copy or move files over to this CD-ROM drive.

This error message can occur because individual files cannot be deleted from the CD-RW. You cannot use the CD disc recording feature of Windows XP for random-access storage while you are writing to disc.

To set the service to Automatic, follow these steps:
1. Click Start, click Run, type services.msc /s, and then click OK.
2. Double-click IMAPI CD-Burning COM Service.
3. Under Service Status, click Start.
4. Try to write data to a CD.
