Moving one partition from boot drive to separate SSD

My main HD started showing signs of failure so I used the opportunity to replace all the HDs with SSDs. I used True Image (clone) to do it and it worked great.

My questions: the two HDs in my system each had 2 partitions. Disk 0 was C: and D: and disk 1 was E: and F: and both cloned the same way to the SSDs.

I'd like to split off D and F to separate SSDs, so I'll have a total of 4 in the system, each with one partition. I know Clone can't do that. Can Disk Director? And if so, how would this be done? The interface on the program is a bit of a terse mess.

Thanks.
