NTFS - Filename from block number

I am trying to recover an NTFS (Windows 7 x64) format drive with seven contiguous unreadable blocks.  I know the block numbers (from Acronis), but not what file(s) are stored in that range.  Does anyone know of a utility which can tell what file(s) are stored at specific disk address?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

The location of each file and directory is stored in the MFT

By the nature of the MFT there is no reverse lookup, so to determine if there was a file or folder using a specific block, one would have to enumerate the MFT.

Thank you for the response!  I'm familiar with the NTFS structure (I've read the Windows Internals books plus a few others).  I'm just looking for a utility that already does the lookup.  It's not worth the time to write one from scratch.  PerfectDisk actually comes close, but doesn't have the necessary resolution.

I have used WinHex as a data recovery tool for over 15 years now and one of the features I very much like is that it gives me a text report of the unreadable sectors and fills those sectors on the destination drive with UNREADABLESECTOR.  I also found a utility ( http://www.easexp.com/xsearch/ ) which lets me search the entire destination drive for UNREADABLESECTOR and reports which files contain that string.
In most cases; though, I warn the client that there will be some damaged files; but, that the vast majority of their files are fine.
If Acronis filled the unreadable blocks with a known string, try XSearch to locate the files.

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Early this morning I restored the backup.  It looked as usable as the original disk so I decided to risk losing the bad sector info and running a chkdsk /r on the original drive.  Luckily, it gave me good file name information as it replaced the bad clusters.  The two files were easy to get rid of so I'm all set.  I will take a look at the WinHex/EaseXP combo.  That could be very handy in the future.  Thanks...
