Interesting... will this also work for a rebuild/recovery? If so, how do I start a rebuild from a particular location? (do I just write the sync_min sector before adding the replacement drive to the array, and it will start from there when I add it?)

Are all sector counts in terms of a drive sector position, or an array sector position?

Thanks,
Michael
