I've been trying to post this all day (Google Groups) without success. Thanks Joel if this posts upon your advice.

Thanks Mladen! That worked perfectly, very much appreciated.
Congratulations on finding that in Metalink as I spent a couple of hours looking at how to do it and still couldn't solve it (maybe I'm getting too old :). I then went and looked at the note you reference and still couldn't find anything to do with "_corrupted_rollback_segments".
I then did a ML knowledge base search (using the flash version, grumble grumble) on "_corrupted_rollback_segments" and it only returned six hits. Only two of those six hits contained the string "_corrupted_rollback_segments"!
I then did an advanced search (unquoted) The Exact Phrase: _corrupted_rollback_segments
And got six hits again with only two hits containing the search string!
