"" DVD multi drive of mu Qosmio G doesn't burn anything
Posted: 25-Nov-2010 21:45
My Matsushita uj-846s doesn't seem to want to burn any cd or DVD at all.
I think that it may have started when I updated the firmware. playing DVDs are fine but playing some cds previously burnt on the same drive seems to be a problem as it doesn't recognise the data written on it.
Other external CD drives can read it when connected to the same laptop.
Has anyone had the same issue and more importantly can anyone help solve this? """
He said I think that it may have started when I updated the firmware and i confirm this: At me the same thing happens. I am sure that the problem is in the firmware.
The Toshiba HowTO document contains the firmware 846F103S3Z.exe
Did you try that?
Otherwise check the firmware updates available on Toshiba European driver page for Qosmio G20. You need to check Archive area of driver download form.
