As I stated earlier you don't need to wipe your HD's unless there are install problems which call for it. Just delete then format new partitions using the booted Win7 installation DVD.
Boot the Win7 DVD, choose Custom install, then use the Drive Options to delete all partitions on both HD's, create new partitions as you wish (take all the time you need to get them right), then format and install Win7 to the partition you create on the target HD which should be plugged into the first SATA port and appear as Disk0. Ignore the 100mb System Reserved partition which the installer will create when you use it to partition.
Following these steps will get you a Perfect Reinstall
