Yes. It is designed to be a superset of all common filesystems, feature-wise. 
So it has support for NT ACLs, POSIX ACLs, UNIX permissions, Apple file types 
and resource forks, etc.

I dunno if Windows is OK with UDF on a hard disk, though I have heard of 
seeing it on USB flash sticks.

Also, UDF is optimized for devices with high seek times -- it tries very hard 
to avoid fragmentation, which might actually be suboptimal on hard disks.
