recording with two cd recorders

[stankycat]

hi,
i have 2 yamahas external cd burners. I wanted to use one as the reader, and one as the burner. This way, mtu 2.4 does not record onto the hard drive, and then wait for me to insert a blank media.
Is this possible.
when i explore my computer, I do see both drives, and they are labled E, F. But when i open mtu, i cant differentiate between one and another.
can anyone help?
