USB external hard drive is not detected

[russell23]

Dear CentOS users,

I am running CentOS-4.4 in my IBM ThinkPad R51. I could able to mount see my external hard drive (USB) in my box. I thought kernel recompilation would help and I did it enabling USB storage options and SCSI options. Even after this my external hard drive is not getting detected. I am attaching my dmesg as a text file. Could any one help me to solve this issue? I already posted a query regarding this issue, but unfortunately didn get any reply. (Administrators kind attention please!!!!!!!)

Any help would be appreciated,

Typically, you will see "sd" or SCSI Disk class devices from dmesg or /var/log/messages. You could just check with a "fdisk -l" as root to see a new drive.

Dear pjwelsh,

Thank you for your kind reply. I did check using "fdisk -l". But it is not showing my external hard disk, it shows only my laptop disk of 40 GB. Could you shed more light on this?
