Update!!

We did find a backup of the D drive on our TSM storage server. I am checking now to see if the LDF file is there and if we can create enough space on the server to restore to a new drive.

Now I am wondering if we restore the backup of the D: Drive to our server as a new drive letter assuming we can't call it D: (maybe we can), how would I tell the database server to look for the recovered LDF on the new drive location?
