Data recovery in cases of service area failure: All modern hard drives have service area (SA). It is an area of the drive which has microprogram (firmware) written on it. Microprogram is written upon special negative cylinders (from -1 to -32), which have significantly lower media density, and which is started during disk boot up […]

DATA RECOVERY IN CASES OF MECHANICAL FAILURES: Head Disk Assembly – HDA is the most sensitive part of every, hard drive since it is critical for operational capability. In our Laboratory terminology, all malfunctions of this assembly are called MECHANICAL failures. Those are: HEADS Reading/writing of data is done by magnetic heads which levitate over […]

DATA RECOVERY IN CASES OF LOGICAL FAILURES: With more then a decade of experience and top of the technology equipment, ou Laboratory can access and identify most file system signatures. Here are only some of the signatures we have in our know-how database: EXfat, FAT 12/16/32, NTFS, HFS, UFS, EXT2/3, JFS, NSSREISER, XENIX, SOLARIS (XFS)… […]

Data recovery in cases of PCB (electronic) failures: The role of Printed Circuit Board – PCB of any hard disk is to provide hard disc with constant power supply and to provide connections with motherboard controller. On early HDD, PCB min and only function was to provide continuous power suplly. All control logic was on […]
