Now I'm confused. I have two times posted my question? Then sorry, that was not my intention.
You have deleted my posting with the comment "dup". Then tell me please where should be the other posting with exactly the same question. This would be fair instread of silent delete.
You put the same post in two different subs...choose the most appropriate sub and put your post there. Posting multiple times is frowned upon.
Your post is not a storage question, as that pertains to the actual storage drives, not migrating to a new os drive. The subjects of each forum should be pretty clear.
