Recover data from a drive

Running HP-UX 11.  I have an 18 GB logical volume that contained two 9 GB physical volumes (not mirrored).  This file system contained ascii data files of data that was archived and purged from a progress database.  The first drive in this volume failed.  The majority of data is recoverable from a backup.  However, there was one folder that was not backed up.  

I forced the volume group to be active.  I obviously can't mount the "good" disk in the logical volume by itself, but I used the "dd" command to dump the data into a file on another file system.  If I use the "string" command on the dump file, I can see the data that I'm looking for.   My question is, is there a way, either from the binary dump file or from the physical volume itself, to restore the data from that drive with the directory structures in-tact?  All I can see in the binary dump file is the file contents.  No directory names or file names.

I just want to recover any directories, sub-directories, and files that exist on that particular drive.

Thanks.
