Hello Tenpin24442218,
If you're importing directly from your camera or SD card, PhD requires that a copy of the photos be made on your PC. That's why "Keep in original place" is greyed out. PhD does not physically import any photos - rather, it records the file path. Once a camera/SD card is disconnected, that file path would become invalid.
To avoid issues, transfer the photos to your PC, even if only temporarily, and import into PhD from your HHD.
