Thanks, Jeremy.  The new HDD is, in fact, exactly the same model # as the rest of the array.  I figured doing it that way would make life a lot easier - it's the same cache, access times, blocks, bytes, everything, and I don't have to worry about anything being any different.  That's also why I'm buying 1 TB drives to use for backups, and they're all going to be the exact same model # - so that when I'm ready to move from a 750 gb storage solution to a 3 tb storage solution, it'll be simple.

fdisk - the Linux way, and then I'll be back up & running.

Well, tomorrow is the day.  Hopefully, I won't be too tired after work to do it mistake-free.

If your new drive is the same size as the old one you don't have to do
anything other than fdisk it as an FD partition, plug it in and
rebuild the array. However, if its larger, you need to make a
partition as the same size as the original disk, mark it as FD in
fdisk and rebuild the array.
