If, your computer starts acting “funny”, and you don’t have ALL your new photos backed up on external storage – do it, do it now! I had worked on this photograph for some time, and then, yesterday, my computer started showing me the dreaded “Blue Screen of Death and Destruction!” It took some trips to “Safe Mode” land and some registry fixing to get the computer half-way stable.
At least, I have been able to off-load all new photographs to external hard-drives.
I know that computer crashes are not usually predictable. The key, I think, is to automatically save to external drives immediately. I should NOT assume that the computer will start and continue to work, when I need it to.
