Can write to DVD, but cannot read


I copied some media files (*.avi) to a DVD+R (Verbatim 16x) using my Hitachi-LG DVD+/-RW GSA-H31N drive on my Dell PC running Windows XP. I am using Nero 7, but after writing the DVD I can see the icons but can’t play the files. WMP 10 gives me error message.

The strange thing is I made another data-dvd with again media files (*.avi), which works fine.

In third case, I copied to data files each about 2GB to DVD+R. DVD drive shows a blank DVD in drive so I cannot read on my Dell PC but I can read on my laptop.

This is weird stuff. I don’t know really what to do. Any suggestions will be highly appreciated.

Any help on this will be appreciated.


Well the DMA off against the burner is bad news & will make burning very slow. Check this thread to fix it.

Well changing DMA to ON resolved the issue. Although Current Transfer Mode says PIO.

Device Type: Auto Detection
Transfer Mode: DMA if available.
Current Transfer Mode: PIO Mode

Thanks guys.

It really needs to be in Ultra DMA mode 2. Could be you have a dodgy IDE cable.

Clearly wmp10 sucks.

Use a software like VLC tool.

This is a new Dell PC so I think cable might be fine. But problem is still there. It’s not 100% gone. What else I can do to resolve the Transfer Mode to DMA?

IDE Channel in Device Manager:

Nero InfoTool results:

I don’t want to update the firmwares yet, because I might lose the drive alltogether.

Thanks for your suggestions.


Try running the VB script in my sig. Download it and execute it with Explorer.

If I run the script then can I restore it to the current state (PIO mode) later on? Has anyone run that vb script before to fix the issue?



You really don’t want/need to have it in PIO mode.

You can change it manually in device manager should you want to.

I uninstall the Secondary IDE Channel which is related to my DVD drive. Here is what I did.

Uninstalled the IDE channel, restarted my PC, Windows detected hardware and installed it. As far as I can remember current transfer mode wasn’t changed to DMA at this point.

Then I shut down my PC. Yesterday I checked it again in Device Manager, it’s fixed. Now it says

Transfer Mode: DMA if available
Current Transfer Mode: Ultra DMA Mode 5

So I think I am out of the woods now.

One last question, I still can’t read the Data-DVDs that I made using PIO mode. Any fix for that?

Thanks TimC for you reply again. :slight_smile:


The data-dvds those I can’t read on my Dell works fine with my IBM ThinkPad T41. The laptop has Matshita UJDA765 DVD/CDRW.
