Thanks Akemi & Lawrence for pointing out the obvious that I was blind to! :D
I overlooked the exclude line for the Centos Update repo so yum took the
wrong kernel update instead. Now downloading 2.6.18-92.1.10.el5.centos.plus
and hopes everything will work after this.

The first day's transfer just completed and it took about 1hr 10 minutes for
101GB, from du -h, which I think is in terms of 1024. So that's like
24.6MB/s which admittedly appears to be around the maximum real world data
transfer rate for USB 2.0. According to some reviews of this WD model, the
Firewire was supposedly up to 1/3 faster (they had figures of 35MBps vs
So I am hoping to see a similar speed from the Firewire here to save some 20
minutes of waiting time, a whole week's backup would be almost 2.5 hours of
Going to reboot the system now with the new kernel and hopes I don't lose
the NIC or something :D
