Partitions on drive not recognized

I have windows 7 pro 64 bit installed on a new computer. Windows is installed on a 128 GB SSD (My C drive. Another drive SATA has two primary partitions, D and E. D is used for most of my programs, E is used for my Data. I want to clone my system to another drive, to use as a backup. I do not want to clone the E data drive.
I used Acronis TI 10 to easily copy the C drive or partition. When I try to copy the the D drive partition which is on the second drive, TI shows the drive in two partitions, but will not allow me to select, the individual partitions. I do not want to copy the data partition, because it is very large. I have tried to do this several times and still cannot figure out a solution. Can someone please help?
Thank you,
Ron
