Hard drives are the most common media in computers, laptops, and servers. The density of disks is increasing, and the speed is growing. Manufacturers of hard drives try to increase the durability and reliability of data storage, but the Achilles heel of all hard drives remains mechanics. We provide the best hard drive recovery services.
Our company provides a wide range of services for recovering files from hard drives (HDD). Our hard drive data recovery center has specialized equipment and a large number of hard drive-donors. Our engineers have been working since 2000 on recovering files and repairing hard disks. Every day, we are brought to the data recovery various hard drives and other digital media.
Typical faults of modern HDD
- destruction of the service information – occurs as a result of failures of the hard drive, poor contact in connections, poor-quality power. A similar failure is especially susceptible to such hard drives as Fujitsu, IBM, Maxtor;
- the failure of the electronics board (controller) – mainly occurs during a power failure. Often, the combo chips (engine controls) fail. This product is subject to Quantum, Maxtor, Seagate, WD;
- damage to the BMG (magnetic head unit) and preamplifier circuit-commutator circuits. Similar malfunctions can occur due to the impact of heads on the surface of magnetic plates or stick of MBG, the switch can fail during a power failure. Typical representatives: Quantum AS +, Maxtor D540X, IBM;
- mechanical damage: the destruction of the surface of the plates (BAD blocks), engine jamming, sticking of magnetic heads. Occur in case of improper operation, factory marriage or due to a large wear of the drive.
Self-recovery of data from a failed hard disk can lead to a permanent loss of your files.
Recovery of information on the HDD with a broken service area
The disk is not detected in the BIOS or is detected incorrectly, while the hard drive can make uncharacteristic sounds or pound. HDD can also be detected correctly, but user data is not available, the system can not boot from this hard drive.
Restoring files from the hard disk, in this case, is to restore the data of the HDD service area. These works are held at the PC-3000 stand, in the technological modes of the hard drive. A particular difficulty in data recovery, in such cases, is the destruction of the hard disk defect tables (translator).
After data recovery, it is possible to fix the hard drive.
Data recovery with a faulty controller
With this fault, the hard drive knocks are not detected in the BIOS or do not show any signs of life at all.
Restoring the hard drive’s performance consists of replacing or repairing the controller and sometimes a floppy disk controller needs to be flashed. After replacing the controller, the data is transferred to a healthy drive.
Recovery of hard disks in case of faults
In this case, the HDD most often knocks or emits sounds similar to screeching, the drive is not detected in the BIOS. There are cases when one or more magnetic heads fail, then the drive can be detected in the BIOS, but the data read in part.
To restore the hard drive requires opening the hermetic unit and replacing the block of magnetic heads from the donor (the same hard drive). The data is extracted from the Data Extractor.
After recovery and transfer of data, both the patient and the donor are not subject to repair and use.
Data Recovery after having Bad Sectors
With this malfunction, as a rule, the operating system stops loading, some folders or files are not readable, while the hard drive can make shuffling sounds.
Information recovery is done by sector transfer to another hard drive using the Data Extractor software and hardware, which in many cases allows you to subtract information with a significant percentage of bad sectors. Then the data recovery takes place at the program level.
With minor surface damage, it is possible to repair your hard drive after data recovery.
Data recovery in case of jamming of the engine or BMG
With the wedge of the engine / BMG, the disc does not spin, which can cause burnout of the microcomputer chip. Also, the surface of the magnetic disk is usually destroyed.
Jamming of the engine is eliminated by repairing it or replacing the pancakes with a healthy drive. In the case of sticking of BMG, the hermetic zone is opened and the heads removed to the parking zone. After that, a copy is made to a working hard drive on the Data Extractor. Winchester operation is not subject to and its repair is impossible.
