I'm confused, are you trying to keep whats on the Windows partition or not.  'df' only shows mounted partitions, not all partitions available to your system.  For example, some more secure systems will place /boot on its own partition, then rail to mount it.  This makes the disk image of the Linux kernel untouchable by malware.  If you do not mount /boot (not needed for  a running system), then it will not show.

In this case, you have a windows drive as /dev/sda and a Linux drive as /dev/sdb.

Have you tried this?
---------------------------------------------------------------------------
#!/usr/bin/env bash

if [ ! -d /mnt/windows]; then
  mkdir /mnt/windows
fi

mount -t ntfs /dev/sda1 /mnt/windows

There are two identical 300-gig hard disks on my computer;
but only one is accessible. When I do 'df' I see only this:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sdb5             7.7G  3.5G  3.9G  48% /
/dev/sdb7             138G  9.5G  129G   7% /home

Hardware detection shows two hard disks: sda and sdb:

#1 &#8206;ATA MAXTOR STM332062
Old device file: &#8206;/dev/sda
Partitions Primary partitions: &#8206;1 (sda1)
Misc Geometry: &#8206;38913/255/63 (CHS)
Disk controller: &#8206;0 -- Module: &#8206;sata_nv

#2 &#8206;ATA MAXTOR STM332062
Old device file: &#8206;/dev/sdb
Partitions Primary partitions: &#8206;1 (sdb1)
Extended partitions: &#8206;3 (sdb5, sdb6, sdb7)
Misc Geometry: &#8206;38913/255/63 (CHS)
Disk controller: &#8206;1 -- Module: &#8206;sata_nv

When I tried to use 'gparted', I see this error:

error: libhal_acquire_global_interface_lock:
org.freedesktop.Hal.Device.InterfaceAlreadyLocked:
The interface org.freedesktop.Hal.Device.Storage is already
exclusively locked either by someone else or by yourself

So, I booted "Part Magic" Linux live CD and screen captured
the contents of the two hard disks as shown at these links:

http://upquick.com/temp/sda.sdb.png

I want to use the second hard disk to backup all my files
on the first hard disk.

What do I need to do to get the second hard disk unlocked
and mounted so I can copy all my files onto it?
