The most commonly used data carriers in IT are hard disks. This is mainly due to the high storage capacity at a relatively low cost. Most hard drives are used as a single volume in the system. Most server architectures have RAID-based disks. For some time, the SSD hard drives have spread due to the enormous speed advantages. These belong to the technical structure of the flash storage media and have nothing in common with the classic hard drive.
The first hard drive was from IBM in the 50sproduced. Since then, many generations of hard disks (HDD) have been developed with a wide variety of capacities and access speeds. The maximization of storage space and speed has increased exponentially within the last few years. This is mainly due to the refinement of the inner workings of a hard disk. The number of platters (data-carrying disks) within a hard disk has been significantly increased, which in turn resulted in an increase in the number of reads or write heads. The construction by means of many mechanical components has a high sensitivity to external influences (tipping / vibration / camber) result. The cause of a defect / failure of a hard disk is more than 70% external influences.
Data recovery from hard disks
In order to meet the high demands on fast technological change, we work closely together with the hard disk manufacturers. We develop our own data recovery services and technologies on this basis. Only through our many years of experience and the constant accumulation of knowledge, we are able to recover data from “antiquated” older hard drive models as well as the latest HDD variants.
Specialize in the data recovery of RAID systems of all types, variants, and configurations. Defects and damage to hard disks Hard disk damage can have many causes. The variety of technologies and types, as well as the number of hard drive applications, provide a tremendous amount of failure causes that can lead to failure and data loss.
The most common causes of errors that we detect in the context of data recovery:
- Electronic, hard disk defects
- External electronics (motor controller, broken lines)
- Internal electronics (preamplifier, motor)
- Overridden servo data, boot code, service area
- Mechanical disk problems
- Damaged, scratched plate surface, surface damage
- Defective (partly broken) read / write heads (head crash)
- No longer movable / fixed bearings
- Destroyed servo data / service area / boot code
- Decentration of individual plates usually with consequential damage
We often process so-called software bugs, even logical bugs that cause problems in the service area and file system partial overwriting or deletion.
Strange and atypical sounds of a hard drive
In some cases, especially with mechanical defects read or write heads, surface damage, bearing problems, engine damage, etc., clearly audible and non-typical noises of the hard disk can be heard.
How does Data recovery hard drive data recovery work?
First, we create a 1: 1 copy of the defective customer data carrier. This will prevent further damage to the original medium. Be sure to choose the data recovery company that does not work on the original media.
In the event of mechanical damage, it is necessary to work on the original data carrier, but only until it is fully functional. In many cases, after full data recovery after the data recovery, no reinstallation of the system is required.
