Hard links on a UDF file system

[Jason Pearce <jason dot pearce at ieee dot org>]

I have a removable disc (IOMEGA REV), and I want to use cygwin to take 
backups using cp -l and rsync as per 
http://www.mikerubel.org/computers/rsync_snapshots/
This requires hard links to work, which they do on the NTFS partitions, 
but the IOMEGA has a UDF file system and they don't seem to work there 
(revealed by ls -i).
I believe UDF supports hard links 
(http://www.k-par.com/pdfs/resources/whitepaper/DVDWhitePaper.pdf), so 
maybe its just Cygwin that does not allow them?
Can anyone help?


Some additional background:
My first thought was to reformat the IOMEGA to NTFS but I found I could 
not. IOMEGA's web site says the following:
*
> *Why does the Iomega REV drive use the UDF file system for PCs?*
> The UDF file system is the file system of choice as it overcomes many 
> of the limitations of other popular file systems. The FAT32 file 
> system has a 30GB format limit and a 4GB file size limitation. The 
> NTFS file system does not support removable media. UDF also allows 
> Iomega REV disks to use advanced ECC error correction on its media.
*I am not sure if that claim is true, but I have not been able to find a 
way to format the disc to NTFS.
