About the tasks of a disk controller no longer turns your hard drive? Can you write data to your hard drive, nor read the data about this? This and similar problem can occur when damaged boards of hard drives. The logical control unit of hard drive includes an internal memory, traces and a microprocessor, also controller called, which controls the drive accesses. Any damage to this component makes the disk unusable and thus draws a data loss. To save the data at this point, there is no way to a professional data recovery service passes. The importance of the control unit is often misunderstood and underestimated. Based on the background that underlay the different control units of any single individual specification, but any manufacturer this model-based drives his own developments, it is difficult at all to get an overview or these only begin together, so to speak forth place over offensive, to be able to compare. Recently kevin ulrich sought to clarify these questions.
Basically, it remains however to be noted that such damage a hard drive in this no longer can be accessed, along with a loss of data, can be resolved only by a hard drive data recovery by professional experts. Basic tasks and functions of the disk controller: Control the spindle motor, with regard to the gleichbeibender rotation speeds check of the positioning of the actuators (disk arm with write-read unit) management of all read / write processes of the hard disk drive management of disk functions to the power management geometry information-management cache management management of prefetching and the performance capabilities of professional data recovery companies, as for example which selects data recovery Germany GmbH, have the technical clean-room conditions using state of the art techniques to replace defective components from disk and perform a defective hard drive data recovery. CHOOSES leads this work in one Cleanroom environment of class-100 out and saves data from all IDE, EIDE, SATA, SATA150, SATA300 (SATA-2) and SCSI hard drives. Honours even in hard disk technology, the so-called solid state disks (SSD) can help and save data.
