span of disk area. When the head make several attempts to read from
the same area of disk multiple times but fails, it generates the
clicking sound. 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. Perform a disk surface scan if the condition of
the hard disk is not too bad. This helps to mark all bad sectors and
prevent your system from writing new data on the marked sectors of
This is a physical damage of the disk platter
when the head of a hard disk scratches the surface of the disk. This

Hard disk drive occasionally produces a
spinning 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 different sectors where the data is stored. It is
important to differentiate this spinning sound from the clicking
sound. This spinning sound can be reduced by defragmenting your hard
drive from time to time.
Defragmentation reorganizes the scattered data
on the hard drive to make accessing of
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.
