Is there a way of upgrading the drive?

I have a latitude 2110 myself here and I was thinking of upgrading the drive from the 160 gigabyte drive in there to either a 500 or s 2 terabyte hard drive for it. To give it some breathing space for it. I have already done this before with other laptops without a problem. This one since it is a smaller unit. And the drive bay for it is concealed from being shown. Can it be done. SSD's I am not looking into due to the high cost of it. But the Terabyte ones look good for it as well to be used.
