Recovering select files from a failing hard disk

Hello,
	I know similar questions have been asked on the list, but this
one has a slight twist to it.
	I have a failing hard disk that I want to recover only a few
directories from, so I was wondering..

1. Can I bypass mounting or reading certain sections of the filesystem?
2. Can I force part of a drive to be remapped to other sectors?
3. Is there a backup superblock on the disk and what would it be? I know
this feature exists on some filesystems, but I'm not sure if UFS is one
of those filesystems.

	The reason for these questions is that I believe that the
portion of my failing hard disk is involved with the statistics portion
for the data slice or a series of directories. So, I want to grab the
files off my disk and just dump the thing asap.
