try 'dmesg | tail' right after you plug it in and see if you can make out at which sd? it is recognised. Then mount as you would anything else:
mount -t <filesystemtype> /dev/sda1 /mnt/usbharddrive
(provided that's the location of the drive and the directory you want it mounted to.)

i see this: but no idea whats next. what is this '/dev/sda1' mean?../mnt/usbhardrive is fine place.

dmesg | tail

Instead, try an fdisk -l to list what hard drives you have access to. This should tell you some device sd* is available or not.

fdisk -l gives me the below. don't know what is this, "sd" u refer to?
fdisk -l

Disk /dev/hda: 40.0 GB, 40027029504 bytes
255 heads, 63 sectors/track, 4866 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 4801 38459610 83 Linux
/dev/hda3 4802 4866 522112+ 82 Linux swap

The "/dev/sd? " refers to the place that Linux sees the device. Basically all hardware connected to your machine gets a special file under the /dev/ directory. USB drives show up like SCSI drives with names like /dev/sda1 or things like that.

From your fdisk -l output, I don't see the USB disk listed. Maybe there's a driver issue that's stopping it from being seen... I don't know much about the particulars of how USB devices get _in_ to /dev/ ...

to expand on the above: sda would be the first SCSI device recognised by the system, sdb the second etc.
sda1 would be the first partition on the first device.
If this is the first device you have connected to a USB port I'd try mounting sda1.
