How can I create custom cdrom partition on my Ultra Backup 16GB Drive?

Hello.

I have Ultra Backup drive and I don’t need portable soft feature on virtual cdrom drive, but I want to use this this functionality to create partition, for example for installing OS from It.

I read forum and found tool for removing cdrom drive from usb-drive, but how can i resize this partition and load custom content to it? I know, similar tools exists for other flash-controllers, including Sandisk. Please help me to solve this problem.
