OK, I didn't know about the business with it determining raid size based on the first drive. None of that information was in instructions I saw about replacing a failed drive. It just said to make sure that the drive wasn't smaller.

I'd always assumed that the raid, once it was built, stored redundant information on what the size of each of the drives should be and then used only that amount of space when a drive was replaced (even if it was larger). My thinking here was that drive sizes will always go up, and a well designed raid solution should take into account the fact that finding a drive of the same size might be difficult several years down the road. So I guess the copy it makes of the drive 0 configuration data on drive 1 is useless.
