I currently have two drives on my pc, one external on which I save all my pics by default and back up on the other.

Over the past two years I have noticed that some of my pictures were damaged in the following way:

A. The picture is dislocated at the bottow part about 1/3 down, meaning sort of cut in two and top part is dislocated from bottom part about 1mm.

B. At the same time, the colour of the bottom part of the picture is completely modified!!!!
C. Both A and B occur together.

At first I thought maybe it was Windows picture viewer that was creating this, but starting thinking it was a hardware problem because I recently scanned some pics with Zoombrowser from Canon that I took 4 years ago and notice this issue on 5 of my pics which had this issue!!! I had not looked at these pics over the past 4 years and so I sort of put the idea that Picture viewer was the problem.

I find it weird that this could be caused by both hard disks, and starting to think its either Windows or my computer hardware (other than hard disks)??

Any input would be appreciated!!!

I certainly hope someone has a better idea about this than I do. If I understand correctly how you are storing pictures,it sounds to me as if your pictures are being corrupted in the transfer to the external drive, and the corrupt pics are being backed up to your internal drive. This may be due to the way the I/O controller works. Instead of using it in one direction at a time, you are trying for through transfer. The computer is attempting to direct photos from your camera or card reader into a buffer in your computer's memory, and immediately sending them to the external drive using the same I/O controller.

Don't know of an easy way to fix the existing pictures, but would suggest a different storage workflow, such as uploading to internal HD first, and copying from it to your external drive.

I user a card reader and copy CF Card folders onto my external HD.

Once a month or so, I copy as back-up, my whole "photograph" folder to my internal HD. I sort of understand what you say, but my dislocation of pics used to happen even if I copied pic from reader directly onto my internal HD.

I am still at at a lost with how to deal with this, but thanks for you input on this issue.
 
I think you could better diagnose the problem if you knew where/when the images went bad.

Is this problem affecting all your pictures on both drives, or just some older ones?

Is it possible that the images you transferred from the first disk were bad at the time of transfer?

You might take some fresh images off a memory card and check them after each transfer.

If you have a card reader, try downloading them directly from the camera and again from the reader.

Only a small percentage go bad after being on my drive for a good lenght of time.

Only older ones, not recently downloaded ones.

No, even with second disk.

Started transfering from my camera, but am 99% sure it is not from card readers because I allways look at every picture I transfered to my disks in order to classify them and never noticed a dislocation issue when freshly copied! Doing both doesn't change the issue!
