thanks for the feedback. is there anything in the os that shouldn't be moved (clicked and dragged) to the D drive? it says that it can cause programs to malfunction or data loss. For example, it specifically said do not move "program files" file over to D drive, leave it in the OS.
Also, I have tried moving photos (we have a lot) and my computer won't handle it. Even moving one at a time takes hours. I have tried to transfer photos to a USB storage, but then when I try to open them on the USB, it says it's not compatible. So not too interested in that if I lose my photos.
