External harddisk is not mounted--not visible

[hoboy]

I use dual booting, vista ubuntu 9.10.
I have just bought a new 1T external harddisk i have used it on windows to backup some files.
Now I want to backup some documents in ubuntu, but the harddisk is not visible, I can't see it, ok I think the term in Linux is that it is not mounted..
Is there something else one should do ?
