I wish to confirm that a drive wiped with a pattern of "00", contains this data in all blocks. I run:
dcfldd pattern=00 vf=/dev/hda
and get result match
But if with a sector editor I change one "00" to another pattern, I get mixed results. Many times I still get a match result.
Am I running the program correctly.
Also, is it possible to get screen progress updates in the verify mode?
