The problem is you've mounted it on / - the same place /dev/hda2 is
mounted.

The free space it's reporting is the same because it's the free space on
/, not the drive.  df works on filesystems, not drives.

If you haven't created a file system on it, you should do that first:

# mkfs.ext3 -j -L data /dev/hdb1

Then create an empty you want to use to mount the filesystem into:
# mkdir /data

And finally mount that partition into that directory.  If there are
files in the directory you use, you'll hide what's underneath so it
should always be empty.

# mount /dev/hdb1 /data

When you put the entry in fstab, it should be like so (space it to line
up everything else in fstab for readability):
LABEL=data        /data        ext3    defaults  1 2

Always mount by label, never by physical partition.

Cheers,
