Query: Will need Google if you want to recover from disk failure

I have to echo Lamar Thomas's review -- there is precious little on how to recover from a failed drive. You will have to go back to Google to learn how to recover from a single failed disk if using software raid to provide redundancy for your data. Having a paper reference for various types of disk recovery (in the case of not having a readily available web browser at the same site as the raid server machine) was the main reason I bought this book. So I was quite disappointed. Most of the book's material on hardware raid controllers is dated and by nature vendor specific. Moreover much of the material on creation of software raid that this book provides is unnecessary if one creates the raid partitions at installation.
