The hard disk drive (also known as HDD) of your computer is a device within your computer that stores data that has been created on your system. As you use your computer, data is stored and retrieved from the hard drive making the drive crucial to the function of your computer. Most simply explained, the hard drive functions physically almost like a record player where an arm pivots on an actuator axis and lowers onto an incredibly sensitive disk. The head of the actuator arm reads the information contained on the disk and also writes information as it is created by your computer. This disk is known as a platter and for the hard drive to function properly the read/write head on the end of the arm must be able to read the platter, or System Area. When the head is unable to read the SA the arm begins to move back and forth above the platter and strikes the interior of the hard drive, emitting a clicking or ticking noise. This noise signals that the hard drive is damaged in some way, is dead or is dying and there is limited time to access any important data contained on the hard drive.
In many cases, people who hear this clicking noise attempt to open their hard drive and repair the issue themselves by replacing parts. By repairing the hard drive in this way, there is a chance that it could function for long enough to access data stored on the drive, however this is risky and advised against by computer engineers. The goal of accessing the damaged hard drive is simply to gain enough time to transfer data from the hard drive to an alternate storage system. The data can be transferred to another hard drive or any external hard drive or USB device but the original hard drive will no longer be functional. This is highly discouraged by computer technicians as exposing the hard drive to any urban environment can cause irreparable damage to the sensitive platter. Repairs must be conducted in a cleanroom where the air contains far fewer particles than a normal room to ensure no further damage is caused to the hard drive.
Cleanroom repairs are particularly necessary with RAID Recovery, whether 1, 5 or 10.
The best and safest option is to simply turn off your hard drive immediately after hearing any clicking, ticking or buzzing noises. The hard drive is no longer functional and repeated use of the damaged hard drive Read the rest…
