Well, no, I dont want to complicate my existence. I just want to read those kind of values thanks, fvalerin

I wanna know ways to make low-level operations to devices (mainly the hard disk) in .Net Framework by using C++ dll's or something ????? By ways I mean maybe a class or a Windows standard API library (doesnt matter if its not managed code) Specific things I want to know are (mostly consultations) : - the beginning/ending number of cluster and track of files, - the beginning/ending number of cluster and track of folders - the size in clusters of files - the volume serial number - the size in clusters and tracks of a hard disk, etc - can I do "interrupts" ??? Let me know the class or the Api library and the documentation, if there is it. thanks in advance, fvalerin
