In that case I can pick nits as well! I was trying to be brief there. I am not sure if unmounting the disk indeed has flushed all the dirty blocks out. And I am sure that even when the disk is not mounted there can be blocks in the buffer cache that will prevent you from seeing whatever someone else put there after you read your blocks. Doing a echo set cuu off > /proc/dasd/devices should invalidate whatever left in buffer cache for it though, I think.
