According to the documentation the zen imaging engine (img) doesn't
offer a means to verify/check the integrity of an image file. I've been
using Ghost (corporate edition) for the last few years, which offers a
"check" option in the dos/win32 clients. I used this feature regularly
to verify critical images written to the network, burned to DVD for
distribution to service providers, etc.

What does the zen imaging engine do in terms of error
checking/correction during image make process?
