Hard Drive Electronics

Symptoms

  • The hard drive does not power up, therefore it does not make any "spinning noise."
  • The hard drive does not un-park the heads. This can usually be heard as a small click once the platters reach full speed.
  • There is a burnt smell from the hard drive circuit board or there is visible damage to the board or chips.
  • The hard drive repeatedly clicks, bangs, thrashes or makes strange noises. This is less common.

Common Issues

  • This type of failure is often caused by power surges or faulty power supply.
  • With the optimization of modern Drives, simply swapping the electronics with a similar hard drive may be difficult or impossible. In some cases, this may actually cause additional damage.
