RAID 1

I'm posting from a new Windows 7 build.  This time, I have my operating system on a RAID 1 volume.  This kind of arrangement takes two hard drives, "merges" them into a single hard drive, and allows each drive to provide a backup copy of the other.  It's good for reliability; the remaining hard drive simply "takes over" if the other drive fails.

Unfortunately, I discovered that I was unable to create (in BIOS) more than 2 logical volumes in the RAID array.  One volume got used for the boot manager partition, which leaves the rest of the drive (1.4 GB) for Windows 7.

That's not at all what I wanted.  If I don't find a way to keep the OS volume down to a smaller size, I think I'll go back to regular AHCI disks and then plan a backup solution for my OS volume.  I dislike running backups, though.  I hope I find a way to squeeze a 3rd volume out of this array.

edit 7:31pm:

My bad, again.  I misunderstood the use of the word "Volume" in BIOS.  It's good that I try these things out instead of just reading about them.  I still learn from my failures.  :)  So when the BIOS asked me to create volumes, it meant logical "hard drives".  When I create volumes from within an operating system, however, it means logical "partitions".  Oops.

So I'm now using a new, different Windows 7 build from this morning.  This is the correct build that I intended.  I'll experiment with it a bit longer to see if this RAID 1 array will solve the wake-from-sleep problem I've been having in Windows.  So far, it has worked flawlessly.
