There is a difference between having hot pixels and dead pixels.
Dead pixels will show up at exactly the same spot, no matter what the exposure (whether very long or short shutter time) or the ISO setting (whether very low or high).
Hot pixels, on the other hand, show up in high-ISO or long exposure shots. EVERY camera will have these, including the D30. Their appearance and position varies, depending on the situation.
What can you do?
For dead pixels, live with it, and post-process to remove them. That's the advantage of digital. There is software available that you can specify the position of the dead pixel, and batch process your files.
If you really cannot tahan, you can send the camera to the service centre, where they can "map" the dead pixels, and modify the firmware to make these invisible. But be prepared to pay, unless there is some other defect you're sending the camera in for - then you can ask them to ("by the way") remap the camera to blot out the dead pixels.
For hot pixels, just post-process using a noise-reduction software like Neat Image.
Don't worry about it. It's an inherent "feature" of digital cameras. Just go out there and shoot some more.
