Refurbished hard drive, a story...

Last month, we had received clients hard drive for recovery. From the first point of view it was just another common Western Digital drive from the Dragon family WD30EZRX. What was a little different compared to standard hard drives, was the label on the front of the drive, which made it easy to see that it was a "refurbished" hard drive. Refurbished hard drives have come to us before, but the situation was more specific this time.

Interview with Ivan Jurić from DataSector

Almost two years ago when we announced Job Organizer V 3.13 our colleagues from data recovery industry had nothing but very positive reactions. Our software was made from scratch and offers a complete solution made only for data recovery companies. This kind of software has filled the gap that existed on the market since there were no solutions that covered every aspect of data recovery process.

The appropriate HDD head inspection – The light source

The head replacement procedure on a hard drive is one of the most delicate mechanical operation during data recovery process. Due to various types of head damage, this procedure sometimes may takes several tries and donors. In a certain number of cases, engineers need to inspect and clean the heads from all dust and small particles which got stuck on the head’s ferrit. The whole cleaning process should be performed under the microscope and with extreme caution in order to preserve the functionality of the heads.

Track all tasks from PC3000 on a smartphone - PC3K Monitor

Everybody in data recovery business knows that cloning patients does not finish when the working time is over. This process may last from several hours to several days, sometimes even weeks. It often happens that data recovery engineers need to monitor these tasks from their home during non-working time and this is usually done by some available applications for remote desktop access, like TeamViewer for example. However, this option can be a bit hard for the engineers because many windows have to be open at the same time, especially if they need to check more than one computer with PC3000 card.

Organize your data recovery company with Job Organizer 3.13

Job Organizer 3.13 is a software solution developed to help your DR company simplify the usage of procedures and activities that are necessary steps in order for the entire system to function. Job Organizer 3.13 is a symbiosis of activities that need to complete financial, technical and all other internal procedures necessary for a single company to run easy and with no problems. What can be proven to be a problem is how to manage so much administration and internal procedures. For last 15 years the HddSurgery team was designing software that connects all the specific procedures required to successfully run a data recovery company. The result was the software in which we implemented knowledge and experience which we gained while working on vairous data recovery cases.

Overview of HddSurgery projects in 2017.

Last year, as in all previous years, we have tried to raise the quality of HddSurgery products and services to a higher level. We were trying to listen to our clients carefully and based on that our team of engineers have prepared a set of conceptual solutions for head replacement procedures. The HddSurgery team had only one thing on their mind – clients should be given more than they could expect. During the realization of these ideas, the development of new tools was not going smoothly - researching, presentation of ideas, selection, evaluation, design, production, testing, rejection some of the prototypes, preparation of new solutions, re-design... until the moment we did not get the final version of our products with the best performance.

Motor problem on WD Sadle G6 drive

Western digital drives are known for their motor durability and lack of problems with the jamming. However, there can be other problems that can happen with the bearing and no hard drive is immune. The video below shows two identical Western digital hard drives, but there is a significal difference between them - platter rotation speed.

HDDS WD Black 2.5''-3.5'' Ramp set updated model list

Since the publishing, HDDS WD Black 2.5''-3.5'' Ramp set has been a great success. Recently, we have been receiving a lot of inquiries about the new Western Digital 6TB hard drives, which lead our R&D team into a research of the mechanics of these drives. After completing several extensive measuring processes, we came to a conclusion:

Opening the hard drive – Regular vs. Clean room environment

Data recovery sometimes does not require the patient drive to be opened, but when it does, a specific problem occurs - exposure of the hard drive’s interior to the influence of the environment in which the data recovery operations are performed. Compared to the hard drive’s interior, the surrounding environment’s air is filled with particles of different sizes, and if those particles get in contact with the surface of the hard drive platters, they can irreversibly damage the delicate magnetic coating, creating bad sectors and thus permanently erasing the data recorded in those sectors.

Interview with Adrian Merdariu from Serman Recuperación de Datos

1. Hello Adrian, can you tell us something about ''Serman Recuperación de Datos''? - Serman was the first laboratory in Spain and one of the first in Europe starting in this field in 1989. Currently we remain a market reference, we have experienced an exponential increase in the volume of recoveries while downhill in prices. We bet the steady increase in quality and not only focused on the recovery process but in communication with the client. 2. What is your opinion on the future of data recovery, what kind of challenges are ahead us?  - I believe that the future will be an exciting one, probably the challenges will be more in software development than hardware mechanics. No doubt about it, the development of hardware tools shouldn't be on a second plan.

Opening the helium hard drive - Video

Data recovery on helium-filled hard drives may be our reality in the future, according to some data recovery experts. The reasons for putting the helium inside the drive are numerous: heat reduction, increased platter density and speed, reduced waste of energy, increased number of platters from five to seven with more storage, less noise and so on...

HDD actuator

HDD actuator is a device which moves head arm assembly. Its task is, not only to start and secure continuous movement of hard drive head assembly, but also to fully control it. Securing and control of this movement is of crucial importance for performing elementary function of hard drives. Surface area of HDD platters is divided into large (and increasing) number of sectors for data storage.  Actuator brings head arm and its sliders to the right spot over HDD platters, from where data should be read/or where new data should be written. At the same time, electronic controller manage HDD motor operation. Platters are set in position so that firstly actuator, and then sliders, are able to perform their task.

HDD head assembly

Hard drive heads are the most sensitive part of the device. They are responsible for all virtues of modern HDDs, such as read/write speed. However, issues with their functionality represent one of the most common HDD failures. HDD heads movement is electronically controlled. Their ultra-precise positioning over platters, which rotate with (usually) 5400 or 7200 RPM, is not a simple task from the mechanical point of view. Therefore, HDD head assembly and its functionality is considered as a classic example of successful integration of mechanical engineering solutions with electronics and control.

HDD motor bearings

At the very beginning of the hard disk drives development, for the purpose of securing safe, fast, smooth and precise rotation of the HDD motor spindle (rotor) - roller ball bearings were used. They secured satisfactory low friction and high reliability at the time and were logical solution in terms of price, productivity and availability.

HDD Spindle Motor

Hard disk is a compact mechatronic component and there is no lot available space for placing its motor. On the other hand, the motors of the hard disks (called "spindle motors") must be able to generate enough torque so the magnetic platters could rotate at the desired speed. This means that the crucial requirement for spindle motors is the large ratio between their power and size. Hard drive motors are designed for operation at high speeds over a long period of time. This principle is, as such, problematic in the start and can easily lead to defect. Some time ago, in hard drive industry, leading trend was continuous increase of motor speed, so some devices were working on speed over 15,000 RPM.
