Lost Data? What NOT To Do and Why

Herein are given the possible damages computers are prone to and the precautionary measures users should implement when faced with such daunting prospect:

Noises from the Computer

When the computer is powered on, the spinning hard disk has to reach certain speed levels. These speed levels are checked before the read/write head is launched across the platter. Sometimes, the disk might be unable to attain the required speed levels. Repeated checks produce clicking noises. Repetitive clicking noises indicate failure of the hard disk.

Clicking is not the only noise that a hard disk makes. Grinding noises might also emanate from the computer. This noise is caused when the read/ write head comes in contact with the media surface and this badly damages data.

When such unusual noises originate:

• It is necessary to switch off the computer immediately.


• Some people repeatedly switch on and off the computer or run the data recovery software with the hope of rectifying the problem. This further destroys the magnetic coating of the platter.


• Running data recovery software in such circumstances causes 1/0 to be written on the disk. Error gets written and data might get extensively damaged.


• It also increases the stress on the read/write head.

• The computer must not be used in such circumstances. Power fluctuations damage the electronic components.


• Power fluctuations lead to a faulty functioning of the read/ write head and this damages data.


• The computer must be unplugged immediately. Power surges that damage the computer most occur on restoration of electric supply.


• An uninterrupted power supply device should be used to protect the computer.

• The computer must be switched off; no attempt must be made to restart it. Even lingering droplets are enough to short the computer.


• No attempt must be made to dry the hard drive like exposing it to a hair drier. Water contains mineral deposits and with its drying up, deposits remain on the surface of the media. This leads to a head crash when powered on.


• The hard disk must be packed in an airtight plastic bag. This prevents the disk from drying up while sending it to the data recovery company.
