Unable to perform Disc-at-once

**cobra2008** · 26-02-2009

I have Windows XP running on my TOSHIBA Satellite A100 Laptop. Yesterday I tried to burn a DVD but suddenly got an error "unable to perform the disc at once".

So I tried Nero 7, Nero 8, Nero 9 again and again but the same error.

Please help me with this!

How old is the DVD burner and have you updated the firmware in it? It seems that you may have an incompatibility with the media you are using and a firmware update should solve that

Apparently, Nero has a setting under the File/Options… Expert Features tab called “Enable DVD Overburning.” Set this value to its maximum value (4600 MB).

From what I’ve been reading, apparently some DVD-R drives have trouble just recording the standard 4.7 Gb on a DVD-R. So, even though 4600 MB on a DVD-R isn’t technically “overburning,” just having Nero label the action as overburning alleviates the problem.
