As a new user, I have begun creating video projects using AVI files recently transcribed by Digital Transfer Systems, from 16mm movies, into a new portable 320 GB hard drive. Saving as I proceeded, I completed the first project today. Then, to my consternation, I found that one of the two video clips (equivalent to DVDs) in the hard drive has disappeared; the second is still in place. Earlier, each opened in Windows Media Player and played beautifully. I have not tampered with the portable drive.
And of course the Videowave project no longer has the many storyline panels I had laboriously arranged in proper order and trimmed. A search on my new HP Vista Home Premium turns up only the second videoclip. The drive shows a folder for each video, with 5 GB in the second (including the video clip) and 975 MB in the first (with no clip).
I am at a loss. I will be grateful for any advice.

Do you know what you named that first clip? It's likely hiding somewhere, maybe your c drive? Have you left clicked start, documents, to see if it shows up there?

Found it! Thanks, Tom.
