I'm sorry Allen. There is nothing worse than loosing a drive, especially when you don't have a backup. Thus showing the importance of having a good back up routine.
All the software that can retrieve data from a formatted hard drive is very specialized, difficult to use, and extremely expensive. Its not like you just tell it to rebuild drive C. Every step is manual and requires some training to understand how to do it properly because you usually have only once chance to get the data.
There are companies like DriveSavers that specialize in recovering data but they're extremely expensive. I've heard they start around $1000 per drive.
