From my testing, if run in DOS with "Direct ATA", EnCase will remove the
HPA without notice (permamently, not temporarily) and image the entire
drive. If run in Windows or in DOS with "BIOS", it will not find the
HPA.

If you use Fastbloc Classic, it will not find the HPA even in DOS
"Direct ATA" mode. This is not suprising since the ATA protocol in this
case is in the firmware of the blocking device.

Does anyone know what the acquisition tools that support HPA do?  Do
they remove the HPA and give one big image file or do they give a
separate image file for the HPA?

The ImageMaster Solo2 just provides a single image which is the full
size of the native drive.

I'm pretty sure Encase from Dos also does this.
