[CentOS] Help setting up external drive via Firewire
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 http://www.centos.org/modules/newbb/viewtopic.php?topic_id=15767&forum=37 I updated the system's kernel to the CentoPlus [noob at 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 at 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.

It is supposed to be: Linux 2.6.18-92.1.10.el5.centos.plus (See http://www.centos.org/modules/newbb/viewtopic.php?topic_id=15788&forum=37 ) Akemi (nick toracat)

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. Regards Laurence
