How to delete multiple partitions from Disk0

Hi, I re-installed Windows 8 on an mSATA SSD drive and would like to use the regular 2TB drive for data. I accessed Disk Management and hoped to be able to delete all the Dell created partitions, however, I do not see such an option. I've included a screenshot for your reference. I'm able to format the Data (D) drive, but cannot do anything with the other partitions. Thank you in...
