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.

Firmware Database Summary

Last year we announced the Firmware Database, a free service for downloading firmware files for various types of hard drives, intended for data recovery and computer forensics proffesionals. Creating of such service was possible due to collecting a huge amount of firmware files which was provided by HelpDisc Data recovery (HelpDisc spasavanje podataka).

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.

HddSurgery training in Bangkok (Thailand)

After another successful HddSurgery tools training, many companies have shown interest in the presentation of the use of HddSurgery data recovery and computer forensics tools. The next country HddSurgery training was held in was Thailand. It was hosted by the government's Electronic Transactions Development Agency (Public Organization) or ETDA, Ministry of Information and Communication Technology. The training took two days to complete.

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...

HddSurgery data recovery tools training

Last week, HddSurgery held its first official training regarding the usage of HddSurgery data recovery & computer forensics tools. Multiple presentations about principles of hard disk drive mechanics were also a part of the training. At the beginning of the presentation, HddSurgery's marketing manager Miloš Gizdovski welcomed our guests from the United States and France and held brief introductory presentation. Firstly, he presented both of our companies - HelpDisc data recovery, as a company which needs and ideas stand behind creation of HddSurgery, firstly as a tool brand and later as completely new company.

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.
