Need help recovering lost partitions

I have a hard drive which had about 5 ReiserFs 3.6
logical partitions on it until last night.  After
booting up my computer (running Mandrake 9.2) I got
some error messages saying that it needed to fsck the
drive.  It went in a loop for quite a bit of time --
fscking all the partitions and then rebooting, finding
errors again, and rebooting.  I figured out how to get
in manually, and tried backing up my data.  In the
process though my partition table was lost.  (I tried
deleting an ext2 partition I didn't need using fdisk
and when I wrote teh new partition table to disk the
partition was empty).

At some point I decided that enough is enough and
installed Mandrake on another hard drive, and tried
finding partitions using parted and gpart.  Neither
utility managed to detect my partitions.

So I took a big jump.  I put one giant partition on the
hard drive (ReiserFS) and ran reiserfsck --rebuild-tree
-scan-whole-partition.

I was overjoyed to find that the files were there --
6,000+ files and numberous directoies were found. 
However, every file I opened was either filled with
nulls or gobblygook.  

I know the data is on the drive.  However reiserfsck
found them proves this.  However, I figured that
(perhaps) the --rebuild-tree is reading all files from
the start of the giant partition.

How can I go about recovering my data?

Many many thanks in advance,

-Dan
