And does it support compressed and sparse files?
Michael,
Protecting the region from writes coming through a file system using cover files is only part of the problem.
You may need to consider moving your disk metadata anytime you see a write to one of the sectors it occupies. The writes could from a partitioning utility, a format utility or another block storage filter above you that transforms data.
You’ll need to at least be able to move it in the case where you couldn’t defrag a cover file to its current location.
