Three Reasons a Hard Disk Drive May Click


There are a number of reasons that a hard drive may start clicking – none of them are good signs. However, some clicking hard drives are worse than others. 

Service Area Corruption
The Service Area of a hard drive is much like an OS for a computer. If there is damage in the Service Area your drive can click due to bad modules. This may require both logical and physical data recovery work.

Bad Heads
Many people assume a clicking hard drive means a head has gone bad. The heads are the magnetic parts on a hard drive which read and write on the platters. Sometimes, new drives have a bad head due to a manufacturers’ defect. This usually shows up within the first two months of using the drive.

After two years or more, heads may degrade. This causes a hard disk failure due to too many read/write cycles or, more simply put, old age.

Degraded Heads
While a new head will typically go bad all at once, causing catastrophic hard drive failure and a data recovery emergency, a degraded head due to age may read and write, or fail to do so, intermittently. Continuing to run the drive, however, can cause complete hard drive failure. . With more and more data stored in tightly condensed patterns on today’s hard drive platters, the likelihood rises that continuing to run a clicking hard drive will result in catastrophic data loss.
