Sound of Hard Disk Clicking
You hear clicks coming from your hard disk drive, either in the form of clicks or grinding sounds. This can happen when you start the computer from the beginning or half while working on your project.
2. Possible Causes
An irregular click or chunk usually indicates that your hard drive is physically damaged. If you use a disk that is activated by S.M.A.R.T, you might see a disk failure warning that will occur when you turn on the computer. This problem can be caused by the following:
– Head accident
– Bad sector
– Mechanical Error
– Virtual Memory Paging
A. Crash Head
This is physical damage from the disk plate when the hard disk head scratches the disk surface. Therefore the grinding noise is observed when this happens. First, turn off your computer and don’t try to turn it on. Consult a data recovery company immediately and avoid unpacking the disk to fix your problem yourself. Operating without the correct tools and a clean environment can result in further damage that complicates the recovery process.
b. Bad Sector
Usually the bad sector is physical damage from the disk area range. A clicking sound occurs when the head tries to read from the same disk area several times due to unsuccessful attempts. This can also occur when the head cannot calibrate with a media servo track due to the gradual weakening of the magnetic domain on the platter which causes the drive to be continuously reset. If the disk condition is not too bad, the standard process is to scan the surface of the disk. This helps mark all bad sectors and prevents your system from writing new data on the damaged disk area.
c. Mechanical Error
Sometimes these sounds can be caused by damaged spindles, Read Write heads or loose components. If you can still access data on disk, you are strongly advised to immediately back up all your data. Your disk is almost dead. If your disk stops spinning after a few moments clicking sound, you might want to send the disk to a reputable data recovery company to recover your data.
d. Virtual Memory Paging
When your physical memory is full, the drive can do a lot of virtual memory paging while maintaining system operation. This will result in excessive disk activity. To overcome this problem, you can add physical memory by adding more RAM to your computer or using a secondary hard disk to load the swap file.
Hard disk drives sometimes produce whooshing sounds when looking for highly fragmented files. This is caused by spinning disks when the read and write head moves back and forth to access the sectors where data is stored. It is important to distinguish the spinning sound from the clicking sound. This roar can be reduced by periodically defragmenting your hard drive. Defragmentation rearranges data that is spread out on the hard drive to make files and programs run faster. This moves files that are normally accessed to the beginning of the hard disk where data can be loaded at a faster speed.
