Yeah, I would.  The output of fdisk is the canonical info appearing in the
partition table.  The partition table records only a zero length partition 
on /dev/hdb.  You still have options...

If you did indeed see a working hdb1 at some point in the past then it 
looks to me like the parittion table has been altered or has become 
corrupt since you last accessed the drive.

Tools exist to attempt to find lost partitions.  Warning: These tools can
do irreparable damage to your data.  They can also recover your data.
Quite a few tools are available.  Some OSS Linux based tools include gpart
& testdisk.  Both of these utils are on Knoppix I believe.

When trying to recover really important data it makes sense to dd an
image of the disk to a safe place before beginning the recovery attempt as 
this gives you a safety net.

Cheers,

Rob
