I have centos 5.3 installed on a server.
I have a Seagate 1TB USB hard disk partitioned, formatted as ext3 and with data on it. When I plug it into my desktop linux pc I get a device /dev/sda1 which I can mount.

However when I plug this hard disk into the centos 5.3 server the only thing which is shown in the dmesg output is :-
usb 1-7: new high speed USB device using ehci_hcd and address 3
usb 1-7: configuration #1 chosen from 1 choice

what is the content of the /dev folder?
do you have any other fixed drives? like HD, CDs, etc?

do you have any partition on it ?
run fdisk -l to if there are any

you can run also
lvmdiskscan to see if the os aware of it.
if you want to do stuff with GUI install qparted or gparted

run the command lsusb, it should show you a list of USB ports, the once connected should show the device name, if all showed 000 000 0000 ...etc.

Then your kernel did not detect it.

I have the contents of the dev folder shown below in the code snippet box.

The server is a HP DL380G5 and it has a bunch of SATA drives connected to the raid controller card.
It also have a dvd writer drive.

Yes the drive is partitioned and formatted. If I plug it into my old suse desktop linux box it is detected and I can map it as /dev/sda1

I am currently running the following kernel version :-
# cat /proc/version
Linux version 2.6.18-92.1.22.el5xen (mockbuild@builder16.centos.org) (gcc version 4.1.2 20071124 (Red Hat 4.1.2-42)) #1 SMP Tue Dec 16 13:08:49 EST 2008

I have the latest kernel 2.6.18-128.1.10.el5xen installed but would need to reboot the live server in order to activate it.

There's a possibility that your Centos installation does not have the necessary modules loaded.  You'll want to see the usb mass storage and scsi base-system modules.  It's very likely that the scsi driver is part of the kernel instead of a module, so you probably won't see it.

Do an lsmod and paste the results.

I faced a related problem once. On a Dell R200, the front panel USB port did not recognize USB mouse and Keyboard! The simplest solution was to use the USB ports in the back and it worked. Can you please try other ports? Else you may want to investigate into using "lsusb -v"  or lsmod or modprove in figuring out the recognized devices, vendor and device ids and then check whether the corresponding module is present or not.

I previously tried one of the rear ports and then the front usb port and neither worked.

The output of lsmod is shown below.

I didnt disable usb in the bios but that doesnt mean it was disabled when I got it.

I will reboot the server tomorrow and let you know. I should really activate the latest kernel at this point aswell and a reboot and bios settings check will accomplish both tasks.

Yes it turned out it was a kernel/module related issue. I rebooted the server and the BIOS had the USB ports enabled but after booting into the newer kernel it worked fine.
