Symptoms:

These drives will be correctly recognised by the BIOS but attempts to read the data areas of the hard disk will result in read errors at every sector.
The hard disk is not identified in the BIOS at all, although the drive is spinning and not noisy, the data area is completely inaccessible.
The hard disk makes a loud distinctive clicking noise when it is powered up, this is perhaps the worst case of the underlying problem that is common to all drives in these series.

Cause: Corruption of the data located in the service area of the drive, often due to bad sectors

Recovery possibilities: Data Clinic are often able to perform a full data recovery on these Western Digital Caviar drives with the above symptoms.

What if I have one of these drives but the symptoms are different?: This is quite possible. These drives are still prone to all the other problems hard disks suffer from ie. mechnical failure, logical failure, etc.
