Any data modification that is minimally logged has to be written to the data file before the transaction completes
I don't think that's true. If it is, it violates the write-ahead-logging model, which SQL Server uses; only
log records should have to be hardened for a transaction to complete, not data blocks.
SQL DBA,SQL Server MVP(07, 08, 09) Prosecutor James Blackburn, in closing argument in the Fatal Vision murders trial:
If in the future, you should cry a tear, cry one for them [the murder victims]. If in the future, you should say a prayer, say one for them. And if in the future, you should light a candle, light one for them.
