[RESOLVED] How can I read/copy CDFS to NTFS

I have a Seagate External USB3 HD nearing capacity with files I do not want to loose.
The HD is formatted CDFS. I have a new Seagate External HD with a larger capacity.
I WOULD LIKE TO COPY the files from the smaller drive to the larger but my computer
(Using Win XP) does not see the smaller drive. I would prefer to keep the larger drive
formatted NTFS.

Is this possible?

If yes - the how please!

hard drives are not formatted with CDFS. There might be a security partition that looks like CDFS.

Thanks Midknyte.
Problem solved. Faulty USB connection .
