I have just downloaded images from my Kodak DCS760 / 1gb microdrive to my
Mac. One of the images has what I can only describe as a yellow line across
part of the image. It looks just as if someone has used an oxyactelene tool
to burn a hole and then cut the image in half. Any ideas ??
Are you sure its just one image... or possibly every image after that one? What you describe sounds very much like a pixel gone bad. Repair means a trip to Kodak for remapping the sensor. Its a simple and not too costly process (I *think* about $200 out of warranty in the US). Is this sort of what it looks like:

That is a 100 percent view of section of DCS330 image (of a Macbeth chart) with a bad pixel. Note, because this is a one pixel wide line, it may not show up unless viewed at 100 percent.
If it really happened on just one image, maybe it was just an odd event, but I'd be worried about it becoming permanent soon. Usually once a pixel goes bad, it goes bad. It's not uncommon for a sensor to have a few bad pixels. These are mapped out during the initial calibration process for the camera in much the same way that formatting a hard drive tells it to ignore bad sectors. If another pixel goes bad at a later date, the sensor just has to be remapped.
