Dvd player will not play disks that a lap top will. it says can not read disk.


Page 12 of the manual...

Just the CD discussion. DVD is above it on page 12...

CD [CD] [WMA] [MP3] [JPEG] [VCD]

≥ [CD] This unit is compatible with HDCD, but does not support the Peak Extend function (a function which expands the

different bit rates).

§1 Includes single-sided, dual-layer discs.

§2 A process that allows play on compatible equipment.
≥ It may not be possible to play all the above-mentioned discs in some cases due to the type of disc or condition of the recording.

DVD Drive reads CD's but wont read any DVD's


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.

Dvd writter is not working


Replace the rubber belt inside. That rubber belt keeps other rotating parts inside to move faster as the motor is running, replaced it with a tight one so that when your insert a cd the optical inside can easily read your cd. The optical lens need to run with as a desired speed of your ROM xspeed.

Put a new gear belt and replace the old and tired belt inside.

your dvd may have power to open up so that you can insert the cd but the only possible thing that i can suggest is that the cable attached to your dvd may be damaged or try checking if your computer recognizes your dvd and if its not recognized... it may have problems on the cable or the hardware itself.

Dvd writter not working


if the device is set up as a master and not a slave device it may be interfering with the hard drive. check the jumpers on the back of the device. If it's plugged into the same cable as the hard drive it must be a slave device. Otherwise, check your bios upon bootup to see if you it's trying to boot from the device instead of from the hard drive.
