A warning, if you have a FULL memory card
I managed to screw up two memory cards that were full to capacity with images.
I was viewing the images using Windows Explorer in "filmstrip" mode. One of the things this lets you do is rotate an image so that if was taken in portrait (vertical) mode, it will display in the correct orientation. I thus reoriented a number of images. In doing so, I managed to corrupt the Smartmedia cards.
In a card with some available space on it, this is not a problem - I had done it hundreds of times before. But when the card was already full, the write-to-card operation caused problems. I think this operation writes the new, reoriented file before it deletes the original one, and in attempting to write where there was no room, it messed things up. I'm surprised the operating system didn't prevent this.
Anyhow, if you have memory cards filled to capacity, copy the files to your hard disk, and reorient them there. I always do this with any other editing, but thought a mere re-orientation would be harmless.
