The solution i am posting works perfectly for Acer laptops wiht Matshita UJ-850s. I have not tested it on Toshiba yet.
Method 1: Remove the registry entry
WARNING: Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method.
These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. Note If you had installed multiple CD-writing software products on your computer, you need to uninstall the software products before you remove the registry keys.
1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK.
3. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/Class/{4d36e965-e325-11ce-bfc1-08002be10318}
4. On the File menu, click Export.
5. In the File name box, type savedkey, and then click Save.
6. Click the REG_MULTI_SZ data type UpperFilters, and then click Delete on
the Edit menu. When you are prompted to confirm the deletion, click Yes.
Note If this data type is missing, go to Method 2.
7. Click the REG_MULTI_SZ data type LowerFilters, and then click Delete on
the Edit menu. When you are prompted to confirm the deletion, click Yes.
8. Quit Registry Editor, and then restart the computer.
Let us know if it does work for Toshiba too.
