That gave me the following:
    hpmount: /dev/hdc2: This is not a HFS+ volume (Unknown error
    4294967295)
I tried hpfsch -v /dev/hdc2, which gave me a long message (appended at
the end of this email) that ended with:
    Volume was last Mounted by hfsplus kernel module: 
    xL+H
    Invalid total blocks 880, expected 0
    Done ***
    *** Checking Backup Volume Header:
        Unexpected Volume signature '  ' expected 'H+'
        hpfsck: hpfsck: This is not a HFS+ volume (Unknown error
        4294967295)

I then took out that drive and put in a HFS+ drive that only had one
partition on it; that worked fine and when mounted using mount
-thfsplus device mntpoint I saw lots of gigabytes.  

So, I am guessing that the problem is that the original drive was
partitioned into one HFS+ partition and one ext3 partition.  I
originally formatted it into a HFS+ partition on the mac and a "linux"
partition, and then once it was in my linux machine, I reformatted the
non-hfs partition to ext3.  I did this because I don't know how to
format a disk as hfs+ using Linux  Evidently this doesn't work, and I
believe it was the source of the problems.

Thanks,
Ric

the result of hpfsch -v:
