Last week my external hard drive crashed. I've learned the hard and expensive way a very important lesson...BACK UP everything that is important to you. It looks like a lot of the images I've taken since last summer may be lost. Most of the images I have backed up on CD somewhere, but some, like my own personal pictures are lost. I still have one data recovery place who is going to take a look to see what they can do, but its going to come at a nice price.
