Not reading dvd disk - ASUS SDRW-08D2S-U/BLK/G 8X Slim External DVD Writer Optical Drive Black USB2.0 Burner

Try the DVD-disk in some other computer, to see if the disk is the problem in _more_ than one computer.

Try some other DVD-disk in your computer, to see if your Sony drive can read _any_ DVD disks, i.e., if _NO_ disks can be read, then it's time to replace the drive.

Some DVD players will read 'DVD-R' ("minus-R") disks.
Some DVD players will read 'DVD+R' ("minus+R") disks.
Some DVD players will read "both" types of disks.

So, if you're burning onto a DVD+R disk, you won't be able to "play" the disk on your Toshiba DVD-player.

Instead, buy "blank" DVD-R disks, and write on them.

check your drive spesc - it can't not compatible with some disks, there are many formats: DVD-R, DRD+R, DVD-RW, DVD+RW.
some disk recoder applications can leave open sessions and it makes disk readable only on the same drive where it was burnt

its the disk laser sensor is to sensetive that why it canot reads with an ordinary disk or a pirated disk or a disk that has a small scratch.

Hello,

Let me explain some things for you to understand what happened with the dvd drive.

A laptop (or desktop) dvd writter drive is actually build around 2 separate optical systems each specialised to deal with either a cd or a dvd type of disk.
A cd has normally around 650mb - 700mb.
A dvd has normally around 4,3gb - 4,7 gb.

But both disks have the sime size. So the larger capacity disk, the dvd has higher data density as related to the disk surface. Therefore because these disks are being read using laser diodes, each diode must be tuned to a specific frequency for each type of disk. A cd is read/written by a 860 nm diode (infrared) and a dvd is read written by a 630 nm diode (red). These are separate optic subcomponents (by the way, a blue ray disk and reader is called blue ray because of the diode that is used to read them, it's on 437nm and it's emitting blue light).
If your drive will read only cd's and fail to read a dvd then it means that the coresponding optic block for dvd reading has failed. The cd optic system will continue to function as it's not linked to the dvd part.
In this situations there is little to do to save your drive so you should consider the replacement or assistance in a service center for your problem. I'm sorry as we aren't able to fix this without having to dissasemble things and use some service equipment.

If when you insert the disk you hear a whirring and clicking noise, CD spins, and does not read, then that is a problem with the DVD lens.

The DVD lens try to focus on the DVD track, by moving lens pickup and spinning the disk, but cannot read the tracks because the lens is dirty or defective.

Try first cleaning the lens with a DVD cleaner disk. And also if you can see the lens from the outside try blowing some canned air on it.

If this still does not help, then the lens pickup may be faulty, in this case you often replace the whole DVD drive unit inside the DVD player.

A DVD - R disk means DVD Read disk, therefore, in order to burn a DVD you will need a DVD RW (meaning Read + Write)

Also, confirm if you DVD drive accepts DVD(-) and / or DVD(+) disks

My portable dvd player turns on and the disk does not spins but the screen turn light blue and does not read the disk
