CD and DVD copying software.

Dear members:

While in the process of making back-up copies of my applications' CDs and
DVDs I was surprised by a message from Retrospect stating that if I
proceeded to duplicate the disk with the option "Ignore Ownership" checked
important files would not be copied that allowed the duplicate to be
bootable.

Do any of you have experience with using Retrospect to duplicate CDs and
DVDs ? Is this just a standard warning meant for duplicates of drives that
have the operating system installed and that should be bootable copies ? Or
could this affect my back-up copies ?

I would prefer to leave the option "Ignore Ownership" checked as it is my
understanding that it would allow the disk to be read by other computers
instead of only mine. Is this right ? Could my back-up copies become
corrupted or unusable if I leave the "Ignore Ownership" box checked ?

A member of another forum has brought to my attention that while Retrospect
is a good application for backing your system or any drive, it is not
necessarily the most ideal one to use when making copies of CDs or DVDs.
Another issue would be related to copy protection or encryption that may
render the copies of these CDs and/or DVDs non-usable.

From your own experiences what is the best application available (commercial
or freeware) to copy CDs and DVDs that will allow me to make copies of my
programs in a way that the final copies will be identical to the originals ?

I would prefer an application that would also allow me to duplicate the
programs to disk images I can keep in my hard drive if I decide to do so.

Thank you in advance for your help,

Joseph Chamberlain
