Data Recovery Symptoms Of The Main Types Of Hard Disk Failure

Data Recovery - The symptoms of the main types of failure of a hard disk

In this article we examine the four major types of hard disk failure: Firmware corruption, electronic failure, mechanical failure and logical errors. It may occur either alone or in combination. It is also interesting to note that all hard drives have a lifespan and eventually develop bad sectors at any given time.

First > Firmware Corruption

Most people have heard of software (eg software) and hardware (hard drive), but the firmware. The firmware is actually a software code that is embedded in hardware and used to control the puck. This code can be damaged so that the operating system (like Windows) and may not be able to communicate with the hard drive. Since the data is affected in the rule itself is stored, it is almost always recoverable.

If one drive has a firmware bug, mostly normal turn, but it is different, as it is not usually recognized by the host computer's BIOS. Almost always possible to succeed by hard data, but it requires the firmware of the device by a data recovery company, which will then be able to recover data that can be reprogrammed.

Second  > Failure of the electronic

This is the circuit board, sometimes referred to as hard disk drive that can be a sudden increase in peak power or disabled. Sometimes you see the damage to some burning chips on the board of the hard disk. The hard drive is not running, when an electronic failure. In general, no damage to data on the hard disk for a full recovery generally stored possible.

Third > Mechanical failure

This type of error refers to the internal components are defective drive. This type of problem is usually checked on a regular basis, or pops out of the unit. It is important that the user does not delete the album art, if you are not only void the warranty, but also allows the controlled indoor environment and isolates that are contaminated by dust particles. The unit must be disassembled in a clean room.

Mechanical problems are often the biggest challenges for data recovery specialists. When the arm (accessing the written component, the existing data and new data on the disk) the read-write heads bear crashed into the courts, a lot of damage caused. This is called a head crash.

Normally, however, is a head crash rare, and the device has a different type of mechanical failure. The data can be restored in 50% to 80% of cases of mechanical failure.

4th > Logical errors

Logic error term covers a wide range of problems, from simple (eg an invalid entry in the table of allocation of files on the hard disk) to complex (eg data will be overwritten by a bad program that causes image). The success of data recovery procedures for such problems is damaged or deleted data can be performed on the disks, and how the incident occurred in the first place.

The four most common types of hard disk failure, the technical challenges of recovering data. Some data recovery company is 100% of the data from any type of problem to fix, but unfortunately this is a dishonest statement. Potential customers must also be careful, "no solution, no fee" offer made by certain companies. Technicians, of course, would not be willing to spend time relaxing complex can not result in any income and therefore tend to ignore the toughest jobs, but it is at all possible, as "unrecoverable". It is always advisable to get a second opinion if you were told that their data can be restored.
