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).
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.
2. 1 hour to copy 100GB sounds like a very good speed. Obviously theeSATA 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.
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 44Mbps).
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 savings!
Going to reboot the system now with the new kernel and hopes I don't lose the NIC or something :D
