>>>From what I've read in "Inside SQL Server 7.0" it can be done. That book recommends that write-behind caching be disabled. It also notes that some controllers do not allow for it to be disabled and recommends at least one that does. If you like, I'll take a look Monday to find more details. Unfortunately, the book is at my office and I don't have a copy here at home.
