the computer can not open DVD, as if does not recognize it

by Sharif / June 3, 2008 9:12 PM PDT

Hello everybody

Recently I installed a software called Daemon Tools in my laptop & since then my laptop can not recognize DVDs, it can play the CDs but not DVD anymore.

The dvd reader drive seems work properly by checking the hardwares property, & the drivers for the drive are up to date.

I already unistalled the software "Daemon Tools", but the problem still there, the computer can not recognize the DVDs.

the DVD reader is: HL-DT-ST DVD RAM GSA-T20N ATA Device, vista home premium.

Your kind help is highly appreciated.

Waiting to hear from you.

Best

Thanks for your reply, but I searched through google, but it seems the UPPERFILTERS LOWERFILTERS removal is advised when the computer can not recognize the DVD drive, this is not the case in my situation.

My computer can recognize the drive, when I click on the "my computer" icon it shows the DVD Drive, & when I checked the device manager, the DVD Drive is showing there & up to the device manager it should be working properly (no yellow triangle or exclamations mark)

So, what do you suggest?

Thanks in advance for your kind help.

The problem is still there

Thanks for you help
I did what you advised me. I found only the LowerFilters and I removed it, but I couldn't find the UpperFilters.

The problem is still the same, the DVD drive can open the CDs but Can not open the DVDs. I also uninstalled the drivers and restarted the computer and the drivers installed automatically as it should be, but the problem is still there, the drive can read the CDs but not anymore the DVDs.

Waiting for your kind help

Thanks

The drive may have expired. To test this I use a bootable DVD such as Vista or Linux. If that fails the drive has failed and we swap it out.

You may not have a bootable DVD (any will do for that test) so try a factory made DVD and VLC PLAYER to try to play said DVD.

We are reaching the point where it's one of the common drive failure modes.

Hi Bob

Thanks for your reply

In fact I just cleaned the DVD lens, & the DVD starts reading the DVD again & the problem solved.

Thanks

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
