Click start, run , type diskmgmt.msc, locate your new drive then right click and partition it then right click and format it.

You are a star, wonderful job!

I assuming that that did help you to fix your problem? :-)
When ever you buy a new hard drive or a new external hard drive it must always be partitioned and formatted before it can be used. Bear this in mind and you should never have the same problem again.

I'm glad you got your problem fixed and I'm glad I was able to help. :-)
