I got a WD 1TB My Book with eSATA/USB/Firewire400 connectivity to backup
data on a client Centos 5.1 machine.
USB 2.0 works fine out of the box but is rather slow, Nautilus predicts
about 1+ hour to fully backup just one day's worth of data or about 100GB.
So I was hoping Firewire would be faster, which is why we got the
version with all 3 interfaces to experiment with first.
Following the suggestions given to another user here

I updated the system's kernel to the CentoPlus
[noob@localhost ~]$ uname -s -r
Linux 2.6.18-92.1.10.el5
After a reboot, everything appears to work as expected, with the
motherboard's TI Firewire controller detected
[root@localhost ~]# lspci | grep 1394
04:07.0 FireWire (IEEE 1394): Texas Instruments TSB43AB23
IEEE-1394a-2000 Controller (PHY/Link)
However, now I'm stuck as the system does not appear to detect the drive
when I connect the firewire cable and turn it on.
I've followed some of the suggestions to check the drive status like
"fdisk -l" but this only shows the drives already installed in the system
"tail -f /var/log/dmesg" shows no new messages when the drive is
connected/powered on
So I'm at a loss as to what else I should be doing to get Firewire to
work and will appreciate any help on this.
Thanks!
2 things jump out:
1. As has already been pointed out that is not a Centos Plus kernel.
Did you reboot after installing the new kernel? (You have to reboot for
a kernel update in order to be running the new kernel).
2. 1 hour to copy 100GB sounds like a very good speed. Obviously the
eSATA interface will be the fastest as it will the the same as having it
plugged directly into the SATA controller. For reference I recently
copied 73GB from an internal SATA drive to an internal (software) raid0
array (made up of 2 SATA disks), and that took 1.5hours.
