Finding and mounting a device

Carpodbt · 07-07-2009, 11:55 AM

I'm new to linux and I was asked to install some drivers from a usb or a usb optical drive onto a linux variant (centos 5.2).
My problem is that I cannot find the device name anywhere so I cannot figure out how to mount it.
Am I going about this all wrong, or is there some obvious way to find out the devices name?
Any help will be greatly appreciated.

use "fdisk -l" you should see some else drivers then "mount" it.

To be honest in linux you are not mounting a device but a file system

USB disks are consider as hard disks here.

Try the command without the USB first.
fdisk -l

take the output of disks carefully.

now plug-in the usb and you can find the new disk which willl be displayed as
sdar sdb or sdc ... like.

create a dir with mkdir /usb
then mount your disk

mount /dev/sda1 /usb (say your disk is shown as sda1)

cd /usb to get your files

You can also view the log..

tail -f /var/log/messages

After you issue that command, plug in your device. You will see the system detect the device and assign it a device node..

Code:

it-lenny:~# tail -f /var/log/messages

This method can also be handy for troubleshooting..
