How data is stored on a hard drive

How data is stored on a hard drive -

When a file is stored on a computer, the data is stored on the magnetic coating of the plate of the hard drive. This magnetic coating on the plates is the 'glue' that holds the data. Any damage to that magnetic coating means that there is no loss of data as each piece of missing coating contains data. So a dish lacks a little 'of the coating has a better chance of a successful recovery of data as opposed to a dish that has had such a huge amount of magnetic coating removed or destroyed.

hard drive failure Parts

typical hard disk components that fail include:

Platters Hard disk platters, or spindle , is rotated by an electric motor. The speed of this rotation is measured in revolutions per minute (RPM) and the greater the yield of the hard drive ... the greater the number of revolutions is that it increases the reading and writing of data to the dishes. Any surface contact for the dishes may cause serious damage to the magnetic strip contains the data. This includes dust, fingerprints, water, and most important of all, the hard drive heads. Platter damage is the most serious type of damage to cause hard disk failure.

Heads (Head Crash) When the hard drive is not actively in use, the heads are parked until the hard drive needs to read or write the data again. And 'when this head moves outside the ultra thin cushion of' air between plates that causes the head to sleep and touches the plate hard drive.

Firmware The firmware is the program instructions can be found on chips on printed circuit board (PCB). Each version of the firmware is specific for its type of hard drive and every hard drive can go through dozens of firmware revisions to increase disk performance that particular manufacturer. The old hard drive, the harder it would be to find a working firmware for that specific model of hard drive.

Printed Circuit Board (PCB) The PCB of the hard drive is the drive electronics drive that manages and operates the hard drive. If a PCB is damaged it is often replaced with an identical PCB with the same firmware on the original hard drive. Typically PCB damage is from water or fire, but there are other reasons why one would fail PCB. And many times a failed PCB affect other aspects such as firmware or heads.

Types of hard disk failure

In general, when a disk is not because of any of the following:

Failure Otherwise known as a medium head [1945004crash] (as described above), the heads of the hard drive is physically touched and damaged the magnetic coating on the plates.

mechanical failure In general, any electronic failure on the hard drive fits into this category. Fire, water, electrical damage to the hard disk may require replacement 'parts'.

PCB Failure As described above, the PCB failure falls in the type of mechanical failure and can typically be 'swapped' for an identical PCB for that specific type of hard drive. Together with the correct firmware for this disc, replacement PCB can be a difficult type of hard drive repair if the hard drive is an older model.

Logical Drive Failure This type of hard drive Failure is usually the least harmful to the data. This type of error usually means that the computer's operating system (or utility) can see the unit, marked as unallocated space, but because MFT computer is corrupted or damaged, it can not read the data. hard drive failure of this type is non-destructive and the chances of a full recovery of successful data are high.

Types of non-mechanical hard drive failure

Other causes for the loss of data and the reason for the recovery of data would be needed could include the following:

natural disasters, extreme weather conditions that are out of our control can make a bad day worse. If your computer has been immersed in water due to a flood, scorched by the fire or near a lightning strike, there is still a chance to recover data from the hard drive.

The human factor accidentally deleting files, formatting the wrong disk drive, and attempt to update your system only operational for failure are the most common problems that come up. Also, be careful as most of the people who are with their laptops, a small drop from the sofa to the floor or down a flight of stairs, is the kind of jarring force to the disk that could cause serious damage to the hard drive platters .

e-mail viruses are usually the way Most viruses are spread from computer to computer. In addition, visiting questionable websites that have scripts, malware or spyware waiting to understand the system and put your data at risk. We recommend running the latest anti-virus software to protect your data from this type of data loss and to reduce the need to request data recovery service.

So how do you protect yourself from losing your data? Back It Up! However, if you need more data recovery services, be sure to use a company that specializes in hard disk recovery data.
