My computer has two 1TB drives in a RAID1 configuration and I added a 2TB drive some time ago, with no problems. This morning I woke to one of the 1TB drives having failed. After shutting down and removing the failed drive, windows 7 booted and Intel Rapid Storage technology started rebuilding across to the 2TB drive.

1) Why did it do this?
2) I shut down the computer and unplugged the 2TB drive. Is the data on that 2TB drive safe? (I shut down when the rebuild process was at 14%).

sounds like a few things may have happend. for what you described to happen, you would have added the 2tb disk to the same array as your raid1. the disk would be usable but part of the raid1 system.

then the failed disk would be the recovery disk. not a big deal in itself, but rapid storage would start looking for a new drive/disk to recreate a new recovery disk from your master disk. however if your shutdown was forced or as a result of a crash, this will happen automatically.

since this process seems to have stared, and got 14% done, i would say that anything on your 2tb drive is gone. if it was still formating, some data may be recoverable using software.

Yeah, looking at the screen when the rebuild was happening, the three drives were listed in the same array.

Think I might have screwed the pooch on this one upon install. Oh well. This is why I do backups.

Thanks
