3.7 is pretty old and may not have support for your SATA hardware, I suggest that you follow the documentation link near the top of this page and readall of the downloading faq, then make yourself a copy of a new version, either 5.1.1 CD ot for a DVD version either 5.1.1 ot 5.3.1.

If the hard drive isn't partitioned then there would be no data on it.

Yea, this last statement was already inferred. However, I'm not able to write a Knoppix book just for you. I suggest that you read a lot of the other information found through that documentation link, then ask specific questions when you have done your homework.
