-.'''SA Emulation Technology'''
-To start with, the concept of ‘Service Area (SA) Emulation Technology’ will be explained, which is also called ‘Hard Drive [[Firmware]] Service Area Emulation Technology’.
-Emulation is used to describe a technology which duplicates (provide an emulation of) the functions of one system using different system, so that the second system behaves like the first system. It also refers to the ability of a computer program or electronic device to imitate another program or device. In reality, this technology has been applied to virtual computer system networks, such as virtual partition, virtual workstation, and virtual storage system. The virtual system is designed to accomplish a certain set of commands. The command set is used to reallocate the calculative resources which also enable the isolation of software, hardware, data, network system and storage system. Basically, the emulator is achieved by the emulation of the command set defined by desired system.
-Emulator can be categorized into different types according to the objective simulated layers. Currently, there are 4 main types of emulations which are hardware emulation, logical emulation, software emulation and application emulation. The Hard Drive Firmware Service Area Emulation Technology has been introduced here. This is a new technology which is used to initialize the firmware information of a specific hard drive by loading predefined SA resource file onto the memory of the external emulator. In another word, the hard drive will boot itself from the information on the emulator rather than from the native firmware information. By using the SA emulator, user can access the data area directly without repairing the '''corrupted firmware'''. This technology is quite similar to the Hot Swap operation where the emulation of SA is achieved by a donor hard drive. Because of the nature of the adaptive information, many modern hard drives are not facilitated themselves to achieve a successful Hot Swap operation. But, by using an external SA emulator, this problem can be resolved.

-== Overview ==
+'''Data Compass''' is a hardware and software data recovery tool produced by [[SalvationDATA]]. The product uses a "3+1 Data Recovery" to restore damaged media. The product is intended to recover data from hard drives with multiple bad sectors, platter surface problems, head instabilities, or are making clicking sounds. A software component is available for filesystem repair.
 Data Compass is a hardware and software data recovery tool produced by [[SalvationDATA]].
-According to our [[3+1 Data Recovery]] process, the stage following the drive restoration will be data recovery using Data Compass.
+== External Links ==
+[http://www.salvationdata.com Official web site]
-After bringing the failed drive back to life, as a data recovery professional, you know now you need to recover the damaged file system by using file system recovery software; and maybe you know also you need to do a disk imaging in order to work from an accurate, stable hard drive image.
-−
-Unfortunately, traditional disk imaging tools and methods are designed for and work on good HDDs only, not the patient HDDs that are unstable or inaccessible because of media defects and instable head, which are common challenges of Stage 2 in practice. Even more, with those traditional imaging tools, the time involved and the ordinary user-level repeated-read access to the media bring a risk of damaging the disk and head, making data lost irretrievable.
-−
-But now there's a better way: The disk probing equipment included in the Data Compass suite bypassing the disk-level problems such as multiple bad sectors, damaged surfaces, malfunctioning head assembly, or corrupted servo info, In the meantime you can use the default software or any other defined software you have been familiar with (R-studio, Winhex, any) to perform file recovery. Through the Data Compass, problem drives will become intact hard drives and ready for file recovery attempts..
-−
-== What can Data Compass do? ==
-−
-−
-Data recovery from physically damaged HDDs is what Data Compass designed for.
-−
-' Data recovery from HDDs with severe multiple BAD sectors, which appear because of platter surface scratch or malfunction or instability of the magnetic head assembly (MHA).
-−
-' Data recovery from HDDs that start to produce "clicking" sounds, which may be caused by corruption of sector servo labels or a MHA malfunction. If some heads or surfaces are damaged it is possible (before installation of MHA replacement) to create a copy of data using the remaining good surfaces or drive heads.
-−
-' Availability of tools for logical analysis of FAT and NTFS file systems in the software complex allows data recovery in cases, when a drive is functional and only logical data structure is corrupted.
-−
-'When used with malfunctioning drives, Data Compass complex often allows selective extraction of data necessary to your customers without reading all data from a drive ("recover data by file" without creating a complete disk image) saving a lot of time. In some cases, when drive malfunctions cause constant self-damage (like scratches on disks or instable MHA) these are the only means to accomplish this task. With the [[ShadowDisk]] technology adopted, users need not to worry about the drive degradation problem.

-== Technologies of the Data Compass ==
-−
-[[SA Emulation]]™ Technology: Feel that too difficult to conduct firmware repair? Or you have come across media defects in the SA (so far no tool in the world can fix this kind of problem)? AnalogT enables us to directly generate key information for booting drive in RAM; therefore, users can initialize the drive and access data area independent of the drive SA. We can disable the read attempt to the damaged SA and access the data directly, no need to try hard to find suitable firmware donor.
-−
-[[DBER]] Dynamic Balancing Enhanced Reading Technology: This easily helps you to extract data from partially damaged bad sectors which can't be copied/ imaged by other tools. Experiments have proved that you will have 30% more data recovery and file opening success rate using DC, compared with other image devices.
-−
-[[ShadowDisk]]™ Technology: It images every sector of the source drive you read to an external shadow disk, any following read request towards those "read" sectors will be directly transferred to the corresponding sectors on the shadow disk; which means each sector of the source drive will experience one read operation during the whole process. ShadowDiskT technology ensures the minimum read towards the source drive; therefore effectively avoid further damage to the media and head, helps you to get rid of the situation before ShadowDiskT Technology: that's the head stack collapses halfway of the disk image and gives clicking sound.
