Subject: Re: Maximum number of files on a disk ?

Two further points:
1. Are all these filed in a single directory?
2. How new is the ubuntu? You're probably using the open source NTFS-g  
emulation, which is itself based on the FUSE filedystem. That ntfs-g  
component did have a bug that resulted in the operation unsupported  
error. It was fixed in a later version
