Yes, by and large, this is true. Your processor which supports RAID normally provides an Alert function which will put out an error display if one of the RAID drives fails. What you need to do is 1) Find out how to use it. 2) Check it daily
Since the RAID drives are quite reliable, as long as you check it daily you will normally have lots of time to get a failing drive replaced. But don't fool around once you see a failure display, you are living on borrowed time until you fix it. =========================================== Cyrus Mead IV [EMAIL PROTECTED] IntelliWare Systems, Inc.

I was told that if you lose one volume of a raid set you can replace and the data will get rebuilt, but if you lose a second volume before you get the first one rebuilt you will lose all the data -- irretrievably! Is this true? Is there any reasonable way to get around it? Is there a reasonable alternative to raid? As always, Many TIA! Dennis -- Dennis G.
