CD vierge mais pas vide !!!

Bonjour et merci de m'aider !
J'ai bien recopié ce qui est écrit sur le disque : CD-R Compact Disc Recordable.
J'avais la copie d'un logiciel dessus, j'ai formaté le disque et tout a été supprimé mais tout l'espace n'est pas disponible.

RE...
J'insiste !!!!! Un CD-R ne peut être gravé qu'une seule fois ! Désolé.

Stands for "Compact Disc Recordable." CD-R discs are blank CDs that can record data written by a CD burner. The word "recordable" is used because CD-Rs are often used to record audio, which can be played back by most CD players. However, many other kinds of data can also be written to a CD-R, so the discs are also referred to as "writable CDs."

The data burned onto a CD-R disc is permanent, meaning it can not be altered or erased like the data on a hard drive. Typically, once a CD has been burned, it will not be able to record any more data. Some CD burning programs can record data as "sessions," allowing a disc to be written to mulitple times until it is full. Each session creates a new partition on the disc, meaning a computer will read a disc with multiple sessions as multiple discs. CD-RWs, on the other hand, can be erased and completely re-recorded. Like CDs, the data on CD-RWs cannot be altered, meaning the disc has to be completely erased each time you want to add new data.
