I have 2 mirrored SATA drives on a 2003 Server. I was using the server as a router and was watching a movie via Netflix on a workstation. Suddenly I lost my internet connection and after investigation I discovered that the entire partition with the OS on it just disappeared. It looks like part of the hard drive isn't partitioned. So both drives lost the primary partition which had the operating system on it. Has anybody seen anything like this before? I had a seperate partition with data on it, and it wasn't touched.
