Needed FAT32/NTFS specifications/descriptions/headers for low-level disk I/O!

Does anyone know where I can found specifications/descriptions of FAT32/NTFS
structures for programming low-level disk I/O to read/write FAT32/NTFS
drives directly from MS-DOS, for example?

Any help would be much appreciated.

I dont think Microsoft will publish the specs for NTFS, it is the heart of their security for NT and they dont want anyone to be able to read or write to it from dos...or anywhere else. Let me check with some friends about fat32 and I'll get back to you on it.

Have you looked in the MSDN library (http://msdn.microsoft.com/library/default.htm)? The Platform SDK and the Windows Resource Kits areas have file system information. The online library does not offer the NT 4.0 resource kits but the 3.51 is there.

By searching the library, some of what I got is:

http://msdn.microsoft.com/library/sd...32ovr_0svh.htm
http://msdn.microsoft.com/library/sd...32ovr_0085.htm
http://msdn.microsoft.com/library/pa...ilesystems.htm
http://msdn.microsoft.com/isapi/msdn...32ovr_6777.htm
http://msdn.microsoft.com/library/bo.../chpt08-07.htm

www.sysinternals.com has information about both of these. IIRC, they have drivers available to use NTFS partitions from DOS, and to use FAT32 from NT 4.0, as well as the low-level information you need to do it on your own.
