No valid drive/disk when dvd is inserted program tells me there's no valid drive or disc found?

CLEAN THE DISK WITH WATER, THEN WIPE , THEN ALLOW TO DRY COMPLETELY . THEN INSERT AND TRY. SHOULD WORK.

Use a factory restore/recovery disc if one is provided when your computer is purchase new. Insert disc into cd-rom and change boot priority or if in startup there is a boot option, use cd/dvd rom as first boot priority and follow instruction. If one disk is not provided, with some (branded such as sony, hp, etc) a recovery/restore partition is created within the harddrive, if this is valid, when booting up the computer, there should be a F-key prompting setup or etc.... if there is press that F key and follow instruction. If partion drive is not created for recovery/resotore, then you must create one disc... You can create this disc when in the operating system, go to your start task and in "all program" see if there is any recovery tools or aplication, which is usually your brand application exm.... acer computer has "acer recovery" and use such program to create a restore disc, once disc is created, turn of computer and set your boot prefernce to cd/dvd and then insert your disc and restart your computer, a black screen will be followed and prompt you that it is booting from cd/dvd rom and follow instruction. If one disc or program is not provide, consult your computer brand and have them send a copy of your factory restore disc for a small fee at your own cost.

Check for cracks or scratches on the dvd disc?It a dvd movie disc,not a computer program dvd disc?Take the dvd disc,washes it with some dish washing soap.To clean all the grims and grease out of the dvd disc laser surface to the dvd player laser eye to read the dvd disc.

hello,

The most common reason for the system not reading discs is a bad drive. The following website sells the drives and does installs:

store.richspsxparts.com/wiiredvddr

This drive should fix any reading issues you are having with your games, or issues inserting your games or ejecting them (or lack thereof). This is the entire DVD drive assembly mechanism replacement for your system including a new laser. If your discs are not ejecting, or you cannot insert a disc -- or you can insert a disc but it will not load, this is what you need to get your system going again!
Hope this will help....

clean the dvd or the dvd drive , try to install it in other pc
to be sure that is you pc or dvd

have you tried a cleaning disk?if not get some cleaning alchol wipe the disk leave a little on it not much,insert the disk ,this might clean the lense.

If the CD or DVD disks you inserted work in some other reader, then your reader is the problem -- even though it is properly connected to your computer, and Windows has the correct device-drivers, it is the "hardware" that is the problem.

When you insert a disk, rotate it to some position, i.e., top-lettering goes in first, and close the drawer. Do you hear the drive start to spin the disk? Open the drawer. Is the disk in the same (non-rotated) position? If so, then the motor that spins the disk is the problem. If the disk does spin, but nothing happens, then it is the "laser" part of the mechanics that is not working.

Replace it.

Check the following parameters

- Type of disk--> it must be a DVD RW disk (Read and write), if the media is only DVD R, you can't burn it
- Your DVD driver--> Check if it accepts DVD RW(-) or DVD RW(+) or both. With this information, check if the media matches the driver capability
- Roxio settings--> In the Main Menu select--> Disc--> Disk information--> confirm that the right driver is selected (drive D or E or the letter your computer uses for the DVD driver)

goto program defaults/media player/disc insertion= and choose the options you require. Or goto computer-cd/dvd drive and choose the program you wish to run the disc

A couple of quick observations: -If you have two or more optical drives you could be inserting the disk in the wrong one. -You may have just misspoke when you said *insert into the DVD/CD burner drive a CD-R disc* but just to make sure you need to be inserting a blank DVD disk and not a blank CD. No offence intended, especially since I?ve made both of these mistakes in the past myself :)
