| when computer users are no longer able to connect to | | | | Placing your hard drive in the freezer to recover your |

| Causes of such failures can be broken down into four | | | | matter; however the internet is littered with examples |
| main categories. | | | | of such practises with alleged successful outcomes. |
| 1.Diagnosis | | | | Hard drive media are based on very precise control |
| Often Neglected this very important first step of the | | | | mechanisms down to a sub micron level freezing the |
| recovery process can make the difference between | | | | media will destroy this precision, not to mention the |
| failure and success, it is worth noting that items 3 and | | | | water content that is now inside the disk enclosure... |
| 4 can be incorrectly diagnosed by untrained attempts. | | | | Hit or tap the media to make the hard drive work, |
| 2. Logical Failure. | | | | contrary to popular belief this will not work either. |
| File system corruption directly affects the logical | | | | Open the drive up for a quick look, you may see the |
| integrity of the user's data and their ability to access it | | | | problem and be able to fix it, highly unlikely that any |
| under normal operating conditions. | | | | untrained computer user will discern anything; in fact |
| Common situations are deleted or virus affected data. | | | | the very opening of the media could yield the media |
| 3. Physical failure. | | | | now unrecoverable. |
| Noisy hard drives such as clicking, ticking or knocking | | | | Clean room, what? Are the necessary? |
