You wearn't defraging while rendering, were you?

I sometimes defrag during a project if the project takes more than one day ( I defrag at the end of the day just before shutting down). Perhaps this is the reason my pre-renders aren't very "sticky" ?

This is a catch 22, as you need to de-frag before printing to tape, so I close the program then do the business, opened V4 and all was lost.
The project file was on a different drive and the pre-renders on a different drive again

Did it this afternoon with the project file in the same folder as the video and all was not lost, just plain odd

I had a thought on this, if you do a search for the Pre-renders, are they actually deleted from the drive, or does Vegas just seem to forget they exist?

I can't see how defragging has ANY effect on Vegas, other than preventing dropped frames in extreme cases. It's a low-level operation that physically re-organizes the files on the hard drive. The physical location of files on a disk is completely beyond the knowledge of Vegas. All it knows or cares about is the contents of a particular file, and whether the disk system can deliver those contents fast enough.

I never defrag my drives, and have never seen dropped frames. I attribute that good fortune to the fact that drives have gotten to be many times faster than the data rate needed by DV. In other words, even if a file is fragmented all over the drive, the disk can still get the pieces together fast enough to not matter.

If you are correct, then my theory might be wrong. I was thinking that maybe Vegas, in order to access files faster, was actually pointing to the location on the disk for files like pre-render, etc. 9which would explain how they can create so many small files and still play fluidly). If this was the case, then a defrag would move the location of the file, making Vegas "forget" that it had pre-rendered.
