No, it is not. NTFS, if one looks at it, is a direct descendant of Files-11, the on-disc filesystem layout for VMS. ODS has several of the elements of NTFS:

* a master file table (INDEXF.SYS => $MFT)

* ACLs, with a system of ACL-bypass privileges

* a whole bunch of special files, with known fixed entries in the MFT, including a block bitmap file and a bad block file (BITMAP.SYS => $Bitmap, BADBLK.SYS => $BadClus)

In contrast, there are significant dissimilarities with HPFS.

That corroborates my reference a bit where author says they made changes to filesystem during the clone of VMS. There would be similarities between the two filesystems if this were true.
