There are three sizes involved:
The size of the media.
The size of the filesystem.
The extent of the data.
In principle, these sizes are in decreasing order (the filesystem should fit on the media, and the data should be within the filesystem boundaries). Furthermore the filesystem on an optical disc is typically adjusted to the data, so copying the ...

To mount a .ccd file created with CloneCD, first translate the file to an .iso file,
ccd2iso MyImage.img MyImage.iso

sudo mkdir /tmp/disk
mount -o loop -t iso9660 ./MyImage.iso /tmp/disk/
