Data Recovery and Diagnosis - What causes a Hard Disk Clicking Sound
Inside of a hard
clicking sounds emitting from your hard disk drive, either in a form
of clicking or grinding sounds. This can happen when you power up
your computer from start or halfway while working on your projects.
The irregular clicking or
chunking sound usually indicates that your hard drive is suffering
from physical damage. If you use a S.M.A.R.T enabled disk, you may
see a warning of a imminent disk failure when you power up your
computer. This problem can be caused by the following:
1. Head Crash
2. Bad Sectors
3. Mechanical Faults
4. Virtual Memory Paging
Here is how to fix the above
This is a physical damage of the
disk platter when the head of a hard disk scratches the surface of
the disk. The grinding sound is therefore observed when this occurs.
Firstly, turn off your computer and do not attempt to power it up.
Consult a data recovery firm immediately and avoid dismantling the
disk to repair the problem yourself. Operating without the correct
tools and a clean environment can result in further extensive damage
which complicates the recovery process.
Typically bad sectors are physical damage of a span of disk area.
The clicking sound happens when the head attempts to read from the
same area of disk multiple times due to failed attempts. This can
also occur when the head is unable to calibrate with the media servo
tracks due to the gradual weakening of the magnetic domains on the
platter that causes the drive to reset continuously. If the
conditions of the disk is not too bad, a standard process is to
perform a disk surface scan. This helps to mark all bad sectors and
prevent your system from writing new data on the damaged areas of
Sometimes these sounds can be a
result of a defective spindle, Read Write head or loose components.
If you are still able to access data on the disk, you are strongly
advised to backup all your data immediately. Your disk is close to
demise. If your disk stops spinning after a period of clicking
sound, you may wish to send your disk to a reputable data recovery
firm to recover your data
Virtual Memory Paging
your physical memory is full, the drive may perform numerous virtual
memory paging at the same time maintaining the system's operation.
This will result in excessive disk activity. To deal with this
problem you can increase the physical memory by adding more RAM into
your computer or use a secondary hard disk to contain the swap
Hard disk drive occasionally
produces a whirring sound when it searches for a file which is
heavily fragmented. This is caused by the spinning platters as the
read-write heads zoom back and forth to access the sectors where the
data is stored. It is important to distinguish the whirling sound
from the clicking sound. This whirring sound can be reduced by
periodically defragmenting your hard drive. Defragmenting
reorganizes the scattered data on the hard drive to make files and
programs run faster. It relocates the commonly accessed files to the
beginning of the hard disk where data can load at a faster rate.
