The book gives a decent overview on the field, but lacks technical accuracy. The authors fumble on technical details. For example, the authors botched the explanation of what happens when a unix file is deleted by claiming that all files with a link count of zero will be deleted. They also make the claim that only the SCSI interface will accommodate the multiple simultaneous communication that RAID requires - when really IDE will do this as well given proper firmware. Another gross oversight was the exclusion of reverse engineering in their investigation of rogue files chapter.When emailing the authors about this, all three ignored the email. I do not recommend supporting authors that ignore their readers.
