There are several causes for this.
Assuming that the 3rd point can be excluded, then please proceed as follows:
In 95/98: The Nero ASPI-driver: Can be downloaded from the ahead Web-Site
In Windows NT: Following ASPI-driver: ftp://ftp.lsil.com/pub/symchips/scsi/drivers/Windows_Drivers/WindowsNT/I386/Tools/ntaspi.exe
Not enough memory to copy this CD. The available space is x MB. It needs y MB.
But according to Explorer there is still enough room on the harddisk (more than x is free), i.e. the figure y must be wrong.
Presumably you have got Norton Unerase installed. Deleted files are not deleted immediately but are given the attribute System, Hidden, Read-Only. The drivers of Norton Unerase make the Windows Explorer see the free memory space as well a the files marked as deleted. Nero does not receive this information.
Please deactivate Norton Unerase or deinstall it.
For the first track only 2-3 seconds are allowed
This error message means that you have set the pause before the first track to an invalid value, e.g. to 0s. This limitation does not apply to other tracks on the CD, i.e. the pause between the other individual tracks can be set as you like, providing the CD Writer can burn in DAO mode or the CD Writer variable pre-gap with a pause of 0s.
The CD is not empty.
Please insert an empty CD.
Please insert an emtpy CD. Please do not insert a CD which has been formatted with PacketWriting Software such as InCD, Prassi abCD, FloppyCD, DirectCD, PacketCD, .. , as CDs formatted like this can only be written on with the respective PacketWriting software. CDs do not have to be formatted to be written on. Please delete a CD formatted in this way using the menu item CD recorder->CD-ReWritable for each user.
This problem has been fixed as of Nero version 4.0.6.2.
Several cases are known in which exchanging the spring solved the problem. In one of the types of CD Writer the spring from a ball-point pen was used.
Presumably WinOnCD / PacketCD is or was installed. Some driver versions of the files C2REC.VXD and C2APIX.VXD (both in the Windows\System\IOSUBSYS directory) cause this phenomenon.
Please remove the drivers mentioned (e.g. by deinstallation). Refer also to drivers of other CD burner programs.
Please continue to read in the following place: Why is it only possible to burn at 2x and not at 4x?
Presumably you are writing on CD-RWs of which your burner assumes that they can only be wrtitten on at a max. of 2x. Not until the actual burning process does your burner check which speed can be used to write on the blank (see also Why is it only possible to burn at 2x and not at 4x?).
Several CD-recorders can no longer write at 1x. Presumably they don't have such a CD Writer. There is no known way to avoid this.
Presumably you have not selected your CD Writer but the image recorder.
In dialog CD-Recorder->Choose CD-Recorder please select your CD Writer .
Presumably you have not selected your CD Writer but the image recorder as for the image recorder these options are unnecessary.
In dialog CD-Recorder->Choose CD-Recorder please select your CD Writer .
Presumably you have not selected your CD Writer but the image recorder.
In dialog CD-Recorder->Choose CD-Recorder please select your CD Writer .

In dialog CD-Recorder->Choose CD-Recorder please select your CD Writer .
In dialog CD-Recorder->Choose CD-Recorder please select your CD Writer .
