The SalvationDATA Data Compass easily helps me get rid of SA

bad sectors which can't be repaired by other drive restoration

products we've been using before, because it gives access to

user data area directly by using its Analog technology which

virtually boot the hard drive SA-independently.

This stage repairs drives that are

undetected, not responding, and drives

that can be accessed but produce null

data. Being the primary stage of the DR

flow, another use of it is to carry out all

round diagnostics to the drive and

decide which stage to follow next.

This extra stage deals with drives with

p h y s i c a l l y d a m a g e d h a r d w a r e

components such as head stack and

spindle motor, which can t be repaired:

the only solution is to replace with a

good one.

This stage deals with drives that have

read inabil ity problems because of

physical/ logical bad sectors on SA and/

or user area.

This stage involves rebuilding the file

system, retrieving the user data and

verifying the integrity of the files.

DATA Extraction & File Retrieval: The key task.

After bringing a failed drive back to life, as a data recovery professional, you know now you need to recover the file

system which may be damaged 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 damaged

HDDs that are unstable or inaccessible because of media defects and unstable 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 lost data irretrievable.

Now in 2008 a world-leading solution incorporating state-of-the-art data recovery technologies changes the mode of data

recovery revolutionarily. Data Compass helps to easily complete the incredible difficult job.

Data Compass is the Stage 2 and Stage 3 tool used in extracting the data and in file recovery.

Powerful Functions of DATA COMPASS

Supporting More Types of Hard Disks

DC supports a comprehensive series of PATA and SATA hard drives,

Including IDE, SATA, 3.5", 2.5", 1.8" and 1.0" from different

manufacturers to do physical and logical data recovery. Also it can be

used for the logical data recovery towards the storage medium such

as FLASH (USB, SD, MMC) and FDD.

Supporting More Types of Partition

Partition Formats

See how the powerful functions make your operation easier and more professional

DC has abundant and creative built-in functions. Whether it is a HD with firmware problem or bad sector, it allows

you to access the data directly like accessing the good working hard disks. With DC, you don't need the

traditional repair.

DataCompass

The following is a brief introduction on how the DC solves your numerous difficult

problems.

You can't access the data from the hard disk or you can read the data from the hard disk, but all the data are

unidentified? Don't worry about it; your data are still on the sectors. With built-in optimized algorithm and DBER

(Dynamic-Balanced Enhanced Read) technology,

. And it can efficiently avoid the endless loop as well as

unresponsive situations while reading the data.

DC can help you retrieve the data from partially damaged bad

sectors which can't be copied/imaged by other tools

File system crashed? Once the file system crashed, the operating system can't get any

information from the hard disk, such as Partition, catalogue, even all the files disappear. It

seems that the hard disk includes no data. The damage may be caused by multiple bad

sectors, damaged surfaces, malfunctioning head assembly, or corrupted servo info, etc.

Data Compass has built in DRS software which is used for logical data recovery.

Using the built-in DRS software, you can directly access the files which are most wanted by customers.

DRS adopts the built-in

algorithm to revise the disordered file structure. What's more, it can search the file header independently, not relaying

on the way of operating system's scanning by sectors.

With Data CompassTraditional method

DataCompass

Via the Sector Editor, you can read the data in sectors. However, once attempting to read the data, the heads will

click continuously. A professional may take risk to solve the problem by swapping the head stack. However, if you

can't find the donor head stack or you never know how to swap it, what will you do? DC has

the professional solution towards the

problems which caused by unstable heads or serious physical bad sectors. When the head

reads the bad sector areas,

Thus it can enhance the head's read and

write ability to the utmost limit of the design, in order to prevent the endless clicking caused

by the head read failure in the original standard working mode. From now on, you don't need

to risk swapping head stack for this kind of disks, cutting the cost remarkably.

(HEPSS--High efficiency power supply system)

the hard disk's control section will automatically increase

the electric output of the head power supply.

As a professional, you may always choose head swap to make HDDs detected by computer. However, because of the

head and sector instability, chances are that the head will be damaged and the sectors will be scratched again by

multiple read operations. Shadow Drive technology of DC can image sectors which have been read to an external

shadow disk. Therefore the future read operation request will be sent to corresponding sectors of the shadow disk.

That means the sectors in source disk which are read many times in the traditional data recovery process will be read

only one time now.

You need know that finding a matching head stack is not an easy task. Herein, DC can reduce the customers'

loss by long time searching for a donor head assembly, and additional cost by purchasing another donor as well as

reduce the high risk of the multiple head swap.

This technology maximally reduces the number of read operations towards the source drive

to effectively prevent further damage to the head and sector as well as avoiding multiple head swap in data

imaging.

It is a great risk of accessing customer's HDD directly through OS. That is because when the OS is reading the sectors,

it will automatically write administrative data into the sectors, which provides convenience to the system resource

management. Unfortunately, this operation will cause the source HDD corruption and data loss, when this

configuration runs on some extremely unstable HDD. DC has a built-in

technology which can block the accessing command beyond this rule via base monitoring to prevent all the accidental

damage. Finally,

"SWPS (safe write-protect system)"

it ensures the 100% intactness of the data on the source HDD when doing data recovery.

Unexpected writes

DataCompass

To HDDs with lots of bad sectors, some traditional tools which can skip bad sectors may help you image eighty percent

of sectors, among which sixty percent have data that can be recovered finally. But in a one-time data recovery service,

the customers' required data are quite possibly among the forty percent you can't handle. You may take several days to

recover the data, but it is useless. That's because the disk imaging tool you are using can only skip the bad

sectors, which causes a large amount of data loss and intactness damage. With built-in optimized algorithm and

technology, Data Compass is able to retrieve bad sectors that are

partially corrupted and cannot be cloned/ imaged by other tools available. Proved by the experiments,

DBER (Dynamic-Balanced Enhanced Read)

you can gain

30 percent more data and success rate of file open than other disk imaging tools.

Serious physical bad sectors may cause the HDDs stuck in data imaging process, which will waste you a lot of

time. The automatic monitor function of DC can realize auto soft reset, auto hard reset and power reset, total three

kinds of methods to automatically reset/reboot drives that become unresponsive because of media scratch, to continue

imaging process and make the program continue the data read operation automatically. As a result, you don't need to

stand around watching and waiting for the entire system to be rebooted. Save your valuable time and labor cost!

The anti-error mechanism of BIOS and OS can prevent you from reading the sectors with physical damage, even

depop the whole HDD. In this condition, all the BIOS-dependent and OS-dependent tools turn to be totally useless.

Meanwhile, you can specify any catalog and file to gain accurate

acquisition.

Equipped with a HOST, DC makes you be available to operate on the HDD to gain more customer data

independently on the BOIS and OS, good or bad.

Your customers have to wait several days or weeks because of

multiple bad sectors or too slow imaging speed? Have you

lost many customers due to speed problem? DC adopts

UDMA100 transmit protocol with transmit speed 6G/M, sector

servo reading technology and totally the factory model. You

can easily backup the data after only one servo reading

process, even for serious bad sectors, at least increasing

efficiency compared with any other imaging

tools available elsewhere.

300% to 500%

Feel it's too difficult to repair your firmware? Or you have come across bad sectors in SA which is headache even

for experienced engineers? Through the new technology, DC directly generates key information for booting

drive in RAM; therefore, users can directly access data area in hard drive without initializing the SA. With the fast

changing hard drive density and models today, such "hot swap method" to access the drive brings us to the times of

"data recovery without firmware repair". We can read damaged SA and access the data directly,

"Analog"

no need to find

suitable firmware donor or do hot swap, especially problems like multiple bad sectors in SA.

The different conditions of data recovery are numerous so we have to carry out different access methods to enhance

the efficiency. But you can't optimize this on the basis of different conditions as ordinary softwares only offer one

single reading mode. DC offers two built-in modes: which you may customize to

your own protocol based on your needs or special conditions. For multiple bad sectors, you may choose PIO to read

more data; for fewer bad sectors, you may choose UDMA. At the same time, you can adjust the two modes with three

selectable methods to control the whole reading process:

PIO protocol and UDMA protocol,

forward image, backward image and leap image.

Worrying your work lost in reading process in power surge? Or you intend to stop the reading process to adjust any

parameters? . As DC has imaged the entire info and

sector map in the target drive and shadow disk (normal sectors, damaged sectors and acquired sectors),

Convenient and worry-free!

DC allows you to stop or continue the read process at your will

you may

stop this program at any time to read any imaged sector.

Do you want to know the whole real-time read process

DC provides comprehensive real-time

monitoring.

so that you can make an analysis and optimize the operation

procedures? Thereby you can get twice the result with half the effort?

Buzzer, LED and procedures scroll bars can offer you real-time feedback of current flow, indicating which

operation is in process on your target drive. Thus it allows you to understand the overall operation of the process and

facilitate your accumulation of experience.

For those professionals who are originally engaged in data recovery, they have a set or

sets of their familiar Phase 3 software products, in other words, the logical data recovery

programs.

The drive restoration products they want to purchase - Phase 1 and Phase 2 devices- can

be in good compatibility with the Phase 3 products they already have, thus no need to get

familiar with another new set of program features.

This feature can make your job easier, more convenient,

especially for those who are involved in the file system restoration for many years. The experts who have their favorite

software will benefit a lot from this considerate design.

DC adopts the open-source design of upper logical software, so you are free to

specify any logical data recovery program you are familiar with, which is used as

the upper recovery software to work with the DC.

Intelligent bad sector leap function: After implementation of the bad sectors attempts

according to the value which is pre-set on the device, the software will try to leap from the

sector skipped and read backward until bad sectors found again, rather than reading directly

forward from identified bad sector. Through this technique, you can get more user data than

other general bad sectors leaping technologies.

You can pre-set a series of read parameters scripts on DC, which allows you control over the full operation process:

Sectors leap, read timeouts, retry attempts, bad sectors repair (ECC processing), optional read mode, the enhanced

error-tolerance algorithms against bad sectors imaging (based on UNC / AMNF / IDNF / ABRT) and read / ready

timeouts.
