  2. 2. DataCompass As a specialist in data recovery world, you know many causes of data loss. In general, we can sum up as follows: Causes of Data Loss HARD DRIVE& * Inexperienced&operation error SYSTEM * Viruses MALFUNCTION LOGICAL 42% PROBLEM 58% * Software program malfunction * Forgotten password LOGICAL PROBLEM HARD DRIVE&SYSTEM MALFUNCTION * Hard Drive with quot;Clickingquot; Firmware * Drive spin motor fault * PCBA damage Firmware contains the commands * Bad sector which make the Hard Disk work and * Firmware / ROM damage a mass of management information * System Area defect such as P-List,G-List,bad sectors and so on. Firmware can be compared to the personal computers operating system. Logical problems you can handle with so much available software. However if you can handle those 42% of the problems of Hard Drive malfunction you can do more data recovery no matter what case you meet. Then people will start calling you quot;Guruquot;, bringing you recognition and leadership in the profession and more business to your company without doubt. Want to get more from every drive? 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. --- Yimei Cao, Lead Data Recovery Engineer CBL Data Recovery Technologies Inc.

  3. 3. DataCompass 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. This stage repairs drives that are This extra stage deals with drives with undetected, not responding, and drives physically damaged hardware that can be accessed but produce null components such as head stack and data. Being the primary stage of the DR spindle motor, which can t be repaired: flow, another use of it is to carry out all the only solution is to replace with a round diagnostics to the drive and good one. decide which stage to follow next. This stage involves rebuilding the file This stage deals with drives that have system, retrieving the user data and read inability problems because of verifying the integrity of the files. physical/ logical bad sectors on SA and/ or user area.

  5. 5. DataCompass 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, 3.5quot;, 2.5quot;, 1.8quot; and 1.0quot; 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. Page 5
  6. 6. 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, DC can help you retrieve the data from partially damaged bad sectors which can't be copied/imaged by other tools. And it can efficiently avoid the endless loop as well as unresponsive situations while reading the data. Traditional method With Data Compass 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. 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. Using the built-in DRS software, you can directly access the files which are most wanted by customers. Page 6
  7. 7. 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 (HEPSS--High efficiency power supply system) towards the problems which caused by unstable heads or serious physical bad sectors. When the head reads the bad sector areas, the hard disk's control section will automatically increase the electric output of the head power supply. 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. 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. 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. 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. Read Image DC does both at one time Avoid further damage to instable heads and sectors ShadowDisk 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 quot;SWPS (safe write-protect system)quot; technology which can block the accessing command beyond this rule via base monitoring to prevent all the accidental damage. Finally, it ensures the 100% intactness of the data on the source HDD when doing data recovery. Unexpected writes Page 7
  8. 8. 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 DBER (Dynamic-Balanced Enhanced Read) 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, you can gain 30 percent more data and success rate of file open than other disk imaging tools. Can do nothing about the left 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! 10 minutes? 20 minutes? 50 minutes? one hour? two hours? three hours? Waiting forever........ Easily get rid of the headache with DC. 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. 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. Meanwhile, you can specify any catalog and file to gain accurate acquisition. DC extracts every byte of available data Page 8
  9. 9. DataCompass Your customers have to wait several days or weeks because of multiple bad sectors or too slow imaging speed? Have you Other imaging tools lost many customers due to speed problem? DC adopts Days or Weeks? 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 Days or Weeks? Done in a couple hours, even less. 300% to 500% efficiency compared with any other imaging tools available elsewhere. 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 quot;Analogquot; 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 quot;hot swap methodquot; to access the drive brings us to the times of quot;data recovery without firmware repairquot;. We can read damaged SA and access the data directly, no need to find suitable firmware donor or do hot swap, especially problems like multiple bad sectors in SA. Acquires data without repairing SA SA Read attempt Using DC User data area SA Read attempt Traditional practice 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: PIO protocol and UDMA protocol, 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: forward image, backward image and leap image. PIO Mode, data transfer rate from 3.3 MB/S to 16.6 MB/S Define access mode yourself UDMA100 Mode, up to 133 MB/S Page 9
  10. 10. DataCompass Worrying your work lost in reading process in power surge? Or you intend to stop the reading process to adjust any parameters? DC allows you to stop or continue the read process at your will . As DC has imaged the entire info and sector map in the target drive and shadow disk (normal sectors, damaged sectors and acquired sectors), you may stop this program at any time to read any imaged sector. Convenient and worry-free! Read Save Interrupt or resume the extraction anytime you want Target Drive Do you want to know the whole real-time read process so that you can make an analysis and optimize the operation procedures? Thereby you can get twice the result with half the effort? DC provides comprehensive real-time monitoring. 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. Real-time report of the extraction 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. 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. 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. Page 10
  11. 11. DataCompass 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. DC gives total control Sector Read time Read Bad sector Leap -outs Retries ECC repair Intelligent bad sector leap function: After implementation of the bad sectors attempts Leap 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 Read backward forward from identified bad sector. Through this technique, you can get more user data than other general bad sectors leaping technologies. Sound quality, green energy--DC passed the malfunction-free test for 100,000 hours. DC electric power consumption : 0.028W. Adopting 2008 newly-released FREESCALE ARM11+ACTEL UDMA and Dual Core chip-processing technology for function controlling, DC provides high-speed, stable and precise control of hard drive image, ensuring each operation secure and credible.
