1. What is “HD Doctor Suite”?
HD Doctor Drive Restoration Suite is an integrated hardware-software combined system that fixes firmware issues for drives of all major manufacturers and popular drive families.
2. Why you need “HD Doctor Suite”?
Being a data recovery professional, surely you have such kind of experience: You have to deal with data recovery from a drive with mechanical drive failures. How would you do then? Some of you may have success with electronic (PCB) problems by replacing PCB parts or directly the whole. But what will be the next when it doesn’t do anything good (even worse)? The firmware problems which need to be handled with these tools are causing 60 percent of all drive failures-up to 80 percent for some models.
3. 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.
* Data recovery from HDDs with corrupted portions in the dynamic system of LBA – PCHS translation.
* 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.
4. What is the highlights of “HD Doctor Suite”?
* Cost-effective design for data recovery companies, you do not need to setup a clean room or purchase the rumorous servo writers, or other expensive equipment.
* Comprehensive drive diagnostics carried out with ease and fast speed towards PCB, head stack, SA, firmware modules and media, the vendor-special diagnostics mode provide exact results to help you decide possible recovery methods. Specialized utilities allow more comprehensive and deeper diagnostics towards the SA and firmware recovery by activating the vendor-special restoration flow.
* Unlike tools developed by some other software companies and the vendors, HD Doctor repairs your drive without damaging the user data, while others only repair drive by erasing/damaging all the user data. HD Doctor is specially designed all its functions into three risk levels: RED, BLACK and GREEN, so to indicate what you can do and what you can’t do during the drive restoration process in case you need to maintain all user data intact.
* Software that comes with HD Doctor runs on Microsoft Windows XP/2000. We integrated lots of operation scripts to be functional buttons to reduce the operation steps for easy-to-use purpose, you don’t need to be an expert or go for training.
* View and edit HD Password using manufacturer protocols for all supported manufacturers. Unlike other products who claimed password removal by Brute Force & Dictionary Attack (which actually remove nothing but wasting your time), we actually “see” the password directly.
* Embedded Engineer Note records the engineer’s operations and reviews, on a case basis.
* HD Doctor comes with a full range of adapters for the most common drive types (2.5″ and 3.5″, PATA and SATA, RS-232 cable, jumpers, programmer…).
* Free upgrade of software and supporting list will be provided to all the customers once available.
* Software is designed to support hard drives based on firmware structure and technology used rather than model number. This enables the HD Doctor to support more hard drive models, including some that are brand new on the market.
* Firmware repository maintained officially and by third parties is continually updated for new drives added to the support list, and you can download them as needed from us.
* “One-Click” auto firmware repair for most common firmware failures: for example, G-list overflow, P-list corruption, SMART module corruption and more. Your data becomes one click away.
* Special design enables you to repair even HDD from different manufacturers at the same time.
* Compared with other software’s complex re-activation process for installation, upgrade or transfer of license to a new host computer; HD Doctor can be run on multiple PCs with one license after activation via USB 2.0 interface, enabling you to perform on-site recoveries.
* Hardware Write Protection switch is embedded, which blocks any possible command that may do harm to the user data.
* Both the complete suite and the partial suite include the HD Doctor console, HD Doctor software, a range of adapters, and you get access to downloads, user forum, and free technical support..

Survey data from companies that specialize in data recovery may be used to investigate the primary causes for how data actually gets lost.
Hard drive failure is the most common cause of data loss, accounting for 38 percent of data loss incidents.
Drive read instability includes occasions where media corruption or degradation prevents access to the data on a disk. This explains 30% of lost data.
Software corruption, which might include damages caused by system software or other program (e.g., a virus attack), accounts for 13 percent of data loss incidents.
User error accounts for 12 percent of data loss episodes. This includes the accidental deletion of data as well as incorrectly partitioning the hard drive.
The relative magnitudes of the different types of data loss are illustrated as bellow. (This analysis ignores data loss due to theft, an increasing problem given the growth in use of laptops).
Causes of Data Loss: (Source: A survey of 50 data recovery firms across 14 countries.)
21 May 2009: IBM announced the results of a study conducted by the I.T. analyst firm Freeform Dynamics, commissioned by IBM, which showed that Linux desktops were easier to implement than IT staff expected if they targeted the right groups of users, such as those who have moderate and predictable use of e-mail and office tools
The research behind the report, “Linux on the Desktop: Lessons from Mainstream Business Adoption,” was designed, executed and interpreted independently by Freeform Dynamics. Feedback was gathered via an online survey of 1,275 I.T. professionals from the U.K., U.S., Canada, Australia, New Zealand and a spread of other countries across Western Europe and the Nordics. Ninety percent of the study’s respondents had direct experience with desktop Linux deployment in their business.
Those with experience of such migrations said that Linux on the desktop was best achieved when it was first targeted to groups of non-technical users. Transaction workers and general professional workers were seen as more than twice as likely to be primary targets for desktop Linux adoption than mobile and creative staff. A majority of the respondents indicated that Linux desktop deployments to these targeted groups was easier than anticipated.
“Some users care a great deal about their desktop computing environment and may be emotionally or practically wedded to Windows,” said Dale Vile, research director, Freeform Dynamics. “The trick is to avoid getting distracted by these, and focus on the users for whom the PC on their desk is simply a tool to get their job done. Migrating a general professional user who only needs to access a couple of central systems, an email inbox and light word processing is pretty straightforward.”
Key statistics of the study include:
71% of respondents indicated cost reduction as their primary driver for adoption.
35% stated the ease of securing the desktop was another primary driver
32% cited the lowering of overheads associated with maintenance and support in general were factors contributing to the benefit of desktop Linux adoption
Those with experience of Linux desktop rollouts are 50% more likely to regard non-technical users such as general professional users and transaction workers as primary targets for Linux
58% of those with prior experience of a Linux desktop rollout see general professional users as primary targets
52% of those with prior experience of a Linux desktop rollout see transaction workers as primary targets.
32% of those with prior experience of a Linux desktop rollout see power users as primary targets.
47% of respondents said usability was the main consideration when evaluating or selecting a desktop Linux distribution for use in a business environment
The study confirmed Linux on the desktop adoption is primarily driven by cost reduction. About twice as many of the respondents cited cost savings over security as the primary driver of why they’d adopt Linux on the desktop. Participants in the study indicated that both environments can be secured adequately — it’s just cheaper to secure a Linux desktop and maintain it that way.
“If a company is a ‘Windows shop,’ at some point it will need to evaluate the significant costs of migrating its base to Microsoft’s next desktop and continuing the defense against virus and other attacks,” said Bob Sutor, vice president of Linux and open source, IBM Software Group. “Savvy IT departments see the Linux desktop as a PC investment that actually saves money during this downturn. We see the recession fueling open source on the desktop.”
The user groups in the study were defined as:
IT operations/support staff
General professional users (relatively light and predictable use of e-mail, office tools, etc)
Transaction workers (mostly using enterprise applications in a routine prescriptive manner)
Other (non-IT) technical staff (e.g. engineers, technical designers/architects)
Office based power users (e.g. finance staff, marketing teams, knowledge workers, etc)
Highly mobile professional users (e.g. sales, roaming managers, etc)
Creative staff (non-engineering, e.g. graphic design)

Slide 1781: What is in the System Area Info. Each category is called a Module and is a UBA block.
1. Smart Data
2. System Logs
3. Serial Number
4. Model Numbers
5. P-List (Primary Defects List – i.e.: manufacture defect info that does not change)
6. G-List (Grown Defects Lists – sector relocation table)
7. Program Overlays – Firmware, Executable Code, or updates
8. Specific Tables like RRO – (recalibrate repeatable run-out and head offsets)
9. Zone Tables
10. Servo Parameters
11. Test Routines
12. Factory Defaults Tables
13. Recalibration Code Routines
14. Translator Data
a. Converts Logical and Physical Address to locations on the drive
b. Heads and Track Skewing Info
15. Security Data Passwords for drive – possible encrypted info.
System Area or System info notes
1. Usually there are two or more copies on different platters of the drive
2. Most of the time system info is on the Outer Tracks – Extreme Outer Edge
3. If info is corrupt it can be copied from the second one to make the drive operable
4. System Log Info can be written here
5. SA – Not Uniformed or standard in any way,
6. Completely different per drive and per drive family
7. Can sometimes be copied from similar drives or drive families using special tools
8. The smaller the amount of data stored in the SA, the more likely it is to replace with parts, PCB’s and heads.

Slide 1816: The System Area is made of UBA Modules (Utility Block Addressing) which are sector blocks logically grouped together that contain a specific MODULE. Each UBA block might be different per a drive manufacturer. The UBA # might be Smart Data on one drive and a different type of data on another drive. The UBA area is inaccessible over the standard interface. Most of the commands to talk to the UBA modules are vendor specific and which is generally not made publically available. There are certain pieces of hardware that can be used to communicate with this area such as the PC3000.
For example: In the UBA 1 Area it could be a Bad Block List. As larger drives have been created there has been a need for larger bad block areas. So this might be expanded from two sectors in a previous drive to three sectors in a newer drive. But the firmware for the drive can still refer to each of them as UBA 1 and does not have to have any changes made to the code in the firmware regardless of the size change.
