I have an external harddisk. When I plug it in the computer, the computer will show nothing (even not show extra partition at all) but the light of the harddisk is lit up. The harddisk is a Samsung G2 portable.

You didn't specify OS, but I'm going to assume Linux is available to you (use a LiveCD if you need to)
Check:
fdisk -l
cat /sys/block/*/device/model
dmesg
lsusb
