 First, check that your PCI-X card has been recognized:

 The chipset on my SATA-II card requires the [[kernel]] module <code>sata_sil24</code>. Simply load this module (assuming your kernel is 2.6.x+):
   modprobe sata_sil24
 then,
-  lsmod |grep sata
+  lsmod | grep sata
 to make sure it loaded.

 After connecting the HDD to the computer via USB, Linux may not always automatically recognise it. The easiest way to manually configure this new HDD is to turn it on and then:
-  tail /var/log/messages
+  $ tail /var/log/messages
 One of the lines should have something like the following:

 The "<code>sda</code>" is the part we are interested in. This means your new HDD is going to use <code>/dev/sda</code> as the mount point.

 Only do the following ''if'' there is a pre-existing partition you wish to delete (note: <code>fdisk</code> may need to be run from <code>/sbin/fdisk</code>):
-  % fdisk /dev/sda
+  $ fdisk /dev/sda
   d   # delete a partition
 The easiest way to create a partition is to use [[fdisk]] (note: Important! You must exercise caution here and only partition un-mounted drives). As root, enter the following
-  % fdisk /dev/sda
+  $ fdisk /dev/sda
   p   # display a list of current partitions
   n   # create a new partition (create a "primary partition")

 It is customary to use the <code>/mnt</code> subdirectory for external mount points. Create a sub-directory here and call it whatever you like (I will call mine "xhdd"):
-  mkdir /mnt/xhdd
+  $ mkdir /mnt/xhdd
 You may want to issue the the following command to grant other users access to the mount point:
-  chmod go+x /mnt/xhdd
+  $ chmod go+x /mnt/xhdd
 Now manually mount the drive and test it with:
-  mount -t ext3 /dev/sda1 /mnt/xhdd
+  $ mount -t ext3 /dev/sda1 /mnt/xhdd
 *Step 5: Add new external HDD to <code>fstab</code>
@@ Line 53: / Line 56: @@
 To test that the above works, first un-mount the HDD (as root):
-  umount /dev/sda1
+  $ umount /dev/sda1
 Then mount it using the information in your <code>/etc/fstab</code> file:
-  mount -a
+  $ mount -a
 This mounts all filesystems (of the given types) mentioned in fstab (unless they are already mounted).

 This step will take a while, depending on how large your external HDD is and other factors.
