hi, i just had the same problem a few hours ago, I was informed I had to initiate the drive and partition/format it.

I did this by start/run then typing cmd
then typing diskmgmt

your missing drive should show here, but as inactive. I right clicked mine and initiated it, then formatted it.

I hope you fare better than me however, as after this I transferred 10GB of files to the new drive and lost the lot :(
