See kindledrm.py for a script to identify DRM-free AZW ebooks.
Hey! Yep, the books I was trying to convert that came up with checksum error were all Tpz. Both in Samples and the Full book. Seems I had a lot of this format and I wasn't aware. Paul was gracious enough to show me how to figure out what format it's in. I didn't know, because when you extract from an IPhone/Itouch the format is always .prc. No matter if it's azw, azw1 or tpz. Good for future knowledge too anyone that uses this device.

Thanks again
