DVD drive not working - "The device is not ready"

Sony 12x40 DVD ROM will not read any CDs - error message "The device is not ready"

Previously erratic performance, problem got worse when a troublesome CD-RW was inserted in the drive now fails to read discs that were previously no problem.

Windows 98 O/S

Any ideas/suggestions?

Sounds as though your drive needs surgery, which can be more expensive than replacing the drive, possibly your laser has slipped.

Have you tried installing the driver? Go to COntrol Panel -System - Hardware - Device Manager, and look for the drive there. Click on it to troubleshoot, or update driver.

Try doing something that will prompt you to place a disc in the drive such as starting a game when it says, do so. Then exit the program and remove the disc. It may work.

The only driver required for CD/DVD-ROM drives and rewriters is the basic Windows CDROM driver; rewriters also require burning programs - try Removing your drive via Device Manager and its Properties before rebooting.

This will allow Windows to reinstall New Hardware and also install the CDROM driver again.

It's unlikely that the laser is out of alignment or requires cleaning - both are very uncommon faults.

Have you also checked that DMA and AutoPlay are enabled and that you haven't also got AutoPlay enabled/disabled somewhere else, such as when using TweakUI?

Your DVD drive does not have DMA turned on . DMA can significantly improve performance. Please read troubleshootig section of the readme file to learn how to turn on DMA transfers."

Whats DMA?

How is it turned on?

Desktop>My Computer>right click icon>select Properties>select Device Manager tab.

Double click on Disk Drives>double click on listed HDD>check DMA box.

Double click CD-ROM>double click on listed CD-ROM drive.>Settings tab>check DMA box.

Click OK>restart.

Means Direct Memory Access.

Thanks for replies re DMA - but I don't think thats the answer to my problem.

The device reads DVDs but not CD ROMs? Any ideas/suggestions?
