i quess not completely. Even Linux kernel can only read/modify files, can't resize or create them so it probably still isn't fully explored.

"forget it" ... the only reliable NTFS implementation out right now is the MS one, which is the reason for http://www.jankratochvil.net/project/captive/ . OpenSores people just aren't good enough at reversing ^_^

NTFS for Windows 98 takes a unique approach to providing cross-platform file system support. Rather than implement code to read and write NTFS drives, NTFS for Windows 98 uses the NTFS and NTOSKRNL system files from a Windows NT/2000/XP configuration. NTFS for Windows 98 wraps the Windows NT/2000/XP NTFS driver in a run-time environment that simulates the Windows NT environment the NTFS driver is written to use. Thus, NTFS for Windows 98 does not rely on potentially unreliable reverse-engineered information about NTFS, provides ultimate compatibility with NTFS, and takes advantage of Microsoft NTFS bug fixes whenever you update the NTFS driver file NTFS for Windows 98 uses to a more recent version

Ok, I was wrong with sysinternals...

But! In my old work, one people demonstred me two-diskette DOS with some third party read-write NTFS driver for DOS. I will try to find out what the hell that was.

two-diskette DOS would most likely be the sysinternals NTFSDOS stuff... or perhaps linux, which has "almost functional" read support and "DANGEROUS! EXPERIMENTAL! OMFG!" write support.

nope, it wasn't linux. it was plain DOS. sysinternals NTFSDOS isn't two disk stuff, it is few KB driver, loaded from autoexec.bat, and it is read-only (that was read-write).

after you add ntoskrnl.exe, ntfs.sy (etc), it's certainly a bit more than "a few KB driver" Wink
