Isn't this just a cluster-size filling issue?
Which is why effective quota security should enable inode limits as well as byte limits.
I'm not going to dive into the 'is it a bug or not' debate, but did want to make a couple of points - A NTFS file system isn't limited by the number of clusters on a disk. The various components of a file are called streams, and the $data stream is just one of them. If a file has a small data segment, then the entire file can be stored in the MFT, along with the security descriptor, attributes, name, etc. So the minimum amount of disk space that a file can take up is the size of one MFT entry, which may or may not involve an additional cluster. If the file grows, then the data stream within the MFT is replaced by a pointer to the cluster where the data is stored. Hence, the concept of inodes isn't germane to NTFS. Hope this clears up some small amount of the confusion... David LeBlanc dleblanc () mindspring com
