Disk sector map?

I was wondering if there is a simple and small utility that will show a list of sectors (or clusters) that a file occupies? When you'd click on a file it would list the sectors and perhaps the number of fragments. Something like:

Sector list for FILE#1.ZIP
6366 sectors in 3 fragments
45000-45128
49143-52564
73483-76300

I have this functionality as part of other "full-size" packages. But a small stand-alone utility would be cool.

 

I think Sysinternals has such a software,, but I can't recall its name right now, it does have disk in it.

 

Got it : DiskView, http://technet.microsoft.com/en-us/sysinternals/bb896650

 

A simple API can do the job.
