Badly Damaged Heads

Working inside a broken hard drive today we came across some of the most damaged read / write heads we have ever seen. First, below is an example of how the heads should look. Notice how straight they are at the ends. Then below are the damaged heads. They are at 90 degrees to the discs (tomb stoning) and would have been scraping the inner disc surfaces to pieces. Bad times!

If you ever hear scraping, scratching or screeching noises from your hard drive, turn it off as soon as possible. If left too long, it could scrape all of the magnetic coating off the discs until there’s nothing left to recover.
