hidden file on CD is not shown in Redhat9

[12345671]

I try to mount OfficeXP installation CD on Redhat9 and on Windows seperately. Redhat9 shows 270MB, windows shows 470MB. Then I check because one hidden file on the CD is not detected on redhat9.
I initially plan to do a backup of this CD on Redhat9. But found this annoying problem, is there any solution for this? Or I can only use Windows PC to backup Windows CDs?

Thanks

... Redhat9 shows 270MB, ...

Hm.
RedHat is a distribution.
Much more informative would be to tell us, which tool shows 270 MB: mc, ls, du, konqueror, k3b, ...?

In which way is the file hidden?

Most burning-software supports modes to burn a 1:1 copy - intended to ignore dirty copy-protect mechanisms.

dd is a tool which is able to ignore file-systems, and copies bytewise entire disks too.

In redhat9, I use graphic interface, right click the mounted CD and properties shows the 270MB. In WinXP, same, right click CD, use properties, shows 470MB

Then I check the CD on WinXP, the some file properties on this CD under WinXP is hidden. Their total size is around 200MB. So I doubt that is the reason.

I want to back up those CDs on my Redhat box(in case the original CD wrong), but not burn them one more time. That is why I want to make copies on Redhat9.

... to make a cd only when needed?

Your 'graphic interface' - perhaps konqueror - might have an option to show hidden files, but I guess it's meant for hidden linux-files (files starting with a dot, like .bashrc).

k3b - a graphical burning software - might have an option to store an iso-image on the harddrive, and AFAIK, an ISO-image is needed, to create for instance a bootcd.
But you should read more about that elsewhere - perhaps k3b has a help section, or google finds more about iso-images.

dd is a commamnd-line tool, and should only be used from experts. I don't recommend that, but you may read it's manpage (man dd) and decide on your own. Again: It might be the the right tool to save the hidden files to your harddrive, but whether and how it would be possible, to create a rescue-cd from it, is very unclear to me.

i suppose your redhat is unix, who cares about size ?
mkdir /where-you-have-space
cd /mounted-cdrom

tar cfb - 126k . |(cd /where-you-have-space; tar xfvp -)

I would strongly advise to use dd to backup your CDs as dd creates an ISO disc image that can be burnt back on to a CD-R/CD-RW directly on both Windows and *nix

dd if=/dev/cdrom of=winxp.iso
