HI,

I would like to implement a OSX file system call interception such as
write call at block level and not at file system level(below FS level).

It sounds like a filter scheme would meet your requirements. Please see <http://developer.apple.com/documentation/DeviceDrivers/Conceptual/ MassStorage/07_Media_Example/chapter_7_section_1.html>.

The sample code in the document is published separately here: <http://developer.apple.com/samplecode/SampleFilterScheme/ SampleFilterScheme.html>
