thanks to both of you. I am at the office now and I will try your tips at home.
I actually tried the search function but I was presented with a lot of search results,the topics of which does not describe my problem. I do not have the time to look at each and every search result. I find it very much faster to post a question than search. Also what word do I put as a search topic? mounting,partition not visible?hd not visible? drives not visible?
Very time consuming. Not to mention that I only have dial-up connection unlike you guys who probably have a 24/7 connection.
