What is head crash?
head accident can be the two most destructive words that the computer owner ever hears, and for a good reason. It is one of the ways that the computer's hard disk can physically fail. The Hard Disk Read/Write head is to fly over the data storage plate below, separated by a gap of less than one dust particle. The gap itself is essential because any physical contact between the head and the plate causes extensive damage to the fine magnetic storage medium. Depending on the severity of the accident, some or all data stored on the unit will be lost. One of the most common causes is vibration or dropping a computer when using. The absence can also be caused by mechanical failure of other hard disk components and an electric increase. Newer hard disk models were built with active hard disk protection, a system that uses a motin sensor to detect acceleration. If the protection system is running, it parks a drive that protects against physical damage.
When a head accident occurs, physical contact between the head and the plate scored the plate surface. The plates are spinning at very high speed and damage with a short contact with the head can be extensive. Scoring destroys data in this sector and also releases electromagnetic dust. This dust has the potential to initiate a chain reaction of continuing accidents if the drive is left in operation.
The accident itself is usually accompanied by a highly behaved sound of grinding or screaming sound. There may also be a repeated click, known as a click on death, a head sound that hits a limiter when the drive tries to calibrate again. Computers that produce these types of sounds should be transported to Professionial repair because attempted to restart them can cause further damage and loss of data.
It can be possible to obtain some data on the disk after a head crash, but only with the help of a data recovery expert. The data in the freeThe days of the contact zone were involved in an invulnerably. Depending on the areas of damage damage may or may not be possible or may not be possible. It is necessary to set up clean to ensure a sterile environment for working on the inner components of the hard disk. This type of data recovery is not a project that can be performed at home.
The cause of the head accident cannot always be prevented and may occur without warning. Experts recommend to regularly back up your hard drive to an external device or online backup service. Installing a new hard disk and recovery from backup is faster, easier and cheaper than attempting to restore data from the head accident, provided the backup is available. Data recovery experts can be expensive and the results are not guaranteed.
