Windows 7 backup tries to format blank disks

[Gormenghast]

When trying to backup to removable media ( CD or DVD ) Windows tries to format blank disks.
I believe this will not work, look at the following link.
Windows Backup does not back up to CD-R, CD-RW, or DVD-R devices
It would appear this type of medium is not supported.

System TipThis article applies to a different version of Windows than the one you are using. Content in this article may not be relevant to you. Visit the Windows 7 Solution Center

When you select a backup media device in Backup (Ntbackup.exe), you cannot select a CD-R (compact disc recordable), CD-RW (compact disc rewritable), or DVD-R (digital video disc recordable) device

Windows 7 does not use Ntbackup.exe.
