LOL, the PC World site lists the file as InfoTool but downloads another Nero Toolkit program called "CDSpeed" .
Download the Nero InfoTool from here:
*www.cdspeed2000.com/files/NeroInfoTool_227.zip
and then once it finishes the diagnostic, select your CDROM and you will be able to see checkmarks on CDR. CDRW, etc. if it supports it.
Like so,
