Re: Dvdrw internal and external will not recognize dvd...

Please give a look at the manual here



Page 17 will tell you what type of CD and DVD you can use.

If you are trying to use a DVD-RW or DVD-R it will not work and it will produce the descibed effect.


Can you please try with a DVD+R and see if it works? If it doesn't work with a + means that the optical drive has some problem and need to be replaced.


Let me know if you need more help.

Dell gx 260 there is no disc in the drive.

OK, first of all you said you put a blank DvD in the drive. Make sure your dell has a DvD writer. Look on the drawer of the drive and see does it say DvDrw or DvDROM. It has to say Rw for rewritable and not ROM for Read Only Media. Maybe you have a Combo Drive that is DvDrom and CDrw which means it will read both DvD's and Cd's but in can only Write CD's.

If in fact you do have a DvD writer make sure you're not trying to put a Blue Ray disc in the drive.

Lastly, remove the DvD from the drive. Click Start/My Computer. Notice what it brings up as to your DvD Drive. Does it Say DvDrw or just plain ole DvD. DvD means it will only read a DvD.

Dvd player,do i have to unhook my internal one ,inordr to use an external dvd burner

No, You should start up pc and after it is to the desktop just plug it into a usb port. Windows should recognize and either load software or ask for disc. Usb devices has to be plugged in or removed live. That is while the computer is running.

Buy a new or used dvdrw for laptop, first take out the laptop battery. Locate the two screws at bottom of your laptop, take them out, whit a paper clip open the dvdrw from a small hole in front of it, pull the defective dvdrw out, if the front plastic face plate is diferent from yours you can change them using a small - screwdriver (be carefull). If you dvdrw have a smalls canals at sides in your defective dvdrw take them out and put them in the new one two, Install the new dvdrw by slowly pushing in to the dvdrw hole until it take its place, put the two screw drivers back + the battery and you shuold be on your way.

Hi charles.It sounds like a Windows error and not the drives so no jumpers or firmware must be changed/flashed.

Instead try to go to device manager and unistall all the CD Devices. Then you have two options. Reboot and the system automatically installs the drives again.

Alternatively you can scan for hardware changes in the device manager immediately after you unistalled the devices.

Hope this helps.
