Greetings!
How do i read any physical block on a disk from Lightsped C?
I've tried PBRead with the parameters as described in IM v2,
it returned "no error" (0) as the status, but 0 actual bytes
read and a zero buffer.

code fragments would be appreciated
direct Email would help me see the answer sooner
thanks
