I noticed this a few versions ago and just verified that it's still the case on 2012; disabling an index and issuing a rebuild (alter index <index> on <table> rebuild) causes some set options to be lost, namely compression.
Why is this?
I was under the assumption that a disabled index maintained all its settings/metadata, it was just the physical pages that were removed.
Is there a technet article which explicitly states which settings need to be manually redefined when rebuilding a disabled index?
