Hi
I am using CDRWIN and is giving me the following message every time I try to burn an iso file

ERROR:File lenght is not a multiple of the CD-ROM sector size

In CDRWIN I select " File backup and tools" then from the drop box i select
"Record an ISO9660 image file"

Is this the right way to do it? if not please tell me how to
and in case I am doing things right what might be wrong?

I have a plexwriter 40x12x40 and CDRWIN Ver 3.9A
