Is Rajeev Nagars book accurate, and should I use it as a reference?
Rajeev Nagar’s book can serve as a good reference text for background, as well as for a discussion of many of the issues involved in writing a file system and/or a file system filter driver for Windows NT. The most significant limitation to the book is that much of it was done against Windows NT 3.51, although it was released just after Windows NT 4.0 became available. Thus, some of the detailed information is no longer applicable. However, since it is the only text available on this subject, it still plays an important role in the reference shelf of a file systems developer.
