Check the depth of field preview with the lens on and the camera on. If the aperture does not react, it may be a problem with the lens rather than the camera. Check the camera with another lens if you have one.

SOURCE: D70 doesn't appear on Mac desktop

This is easily solved.
Most probably the camera's USB connection mode is set to PTP. This is useful for certain situations such as controlling the camera from the computer (you even take photos from OS X's built in Image Transfer).
Change this to "Mass Storage" in the camera settings menu and your camera will behave just like a card reader. Next time you connect it to the computer, plug it it, then turn it on and it will appear on the desktop and in the sidebar as an attached drive.
Don't forget to eject it before disconnecting just as you would an ordinary external drive.

Sorry for the long answer, but this is complicated.

Some photo editors will allow you to set them up to display the date on the photo.

HOWEVER on all digital cameras:

The date taken is part of the image data that is stored in the file, but not as part of the image. If you print directly from the D70, you can set the date and data to print in one of the menus, but this only applies if you print from the camera. There is no way to actually put the date on the image like there used to be in some film cameras. Since the "picture" is now just a set of computer data bits stored on a card, disk, or other medium, the actual picture is defined by the jpeg standard, which is part of the ANSI/ISO/IEC organization. A camera manufacturer could add an extra bit of hardware to generate some kind of laser mark on the digital sensor in the camera, but I'm not aware of any camera that has this. For sure, the D70 does not.

In the various softwares that you can buy to read the file, the information in the file (like the date) can be interpreted and printed any way the software is programmed, including putting it somewhere on the printed output.
