Remove the extra pipe.

Code:
sudo dd if=/dev/sdb count=$((2*16384)) | hexdump -C > /home/bob/Desktop/logfile.txt ; less /home/bob/logfile.txt

Since I do see NTFS how would I fix it?
Much like I said; create a boot sector that matches the place where you found the partition. Without knowing where you found NTFS though, that may be difficult. I'm reluctant to give too general instructions lest it be my fault your drive gets messed up.

Here's a dump I managed to get from the very start of an NTFS partition:

Since you only see a raw device though, not a partition, yours won't be at zero.

NAME

       ntfs-3g.probe - Probe an NTFS volume mountability

SYNOPSIS

       ntfs-3g.probe <--readonly|--readwrite> volume

DESCRIPTION

       The  ntfs-3g.probe  utility  tests a volume if it's NTFS mountable read-only or read-write, and exits with a status value accordingly.  The
       volume can be a block device or image file.

OPTIONS

       Below is a summary of the options that ntfs-3g.probe accepts.

       -r, --readonly
              Test if the volume can be mounted read-only.

       -w, --readwrite
              Test if the volume can be mounted read-write.

       -h, --help
              Display help and exit.

EXAMPLE

       Test if /dev/sda1 can be mounted read-write:

              ntfs-3g.probe --readwrite /dev/sda1

EXIT CODES

       The exit codes are as follows:

       0      Volume is mountable.

       11     Syntax error, command line parsing failed.

       12     The volume doesn't have a valid NTFS.

       13     Inconsistent NTFS, hardware or device driver fault, or unsetup SoftRAID/FakeRAID hardware.

       14     The NTFS partition is hibernated.

       15     The volume was not cleanly unmounted.

       16     The volume is already exclusively opened and in use by a kernel driver or software.

       17     Unsetup SoftRAID/FakeRAID hardware.

       18     Unknown reason.

       19     Not enough privilege to mount.

       20     Out of memory.

       21     Unclassified FUSE error.
