Faulty Hard Disk Drive.


Clicking Drive


When your computer boots from cold it needs to find an operating system such as Microsoft Windows to load into its dynamic memory. An Operating System will have been preloaded on a number of recording tracks on your hard disk drive platter surfaces. A powerful magnetic mechanism called an actuator and servo is initiated by the BIOS and moves read write heads over the platter surfaces, to "seek" and settle on the recording tracks that contain your operating system and data.

Clicking Hard Disk Drive.


The most frequent hard disk failure symptoms reported by Computer Science Labs customers are "Clicking Noises" and "Hard Disk Not Recognised in BIOS".
When the read write heads malfunction the actuator moves the heads across the platters, the servo controls fail and the head assembly returns violently to its backstop, causing a clicking sound.

Clean Air is Essential.


With an operational malfunction such as read write failure you will need the professional services of a Data Recovery company such as Computer Science Labs to repair your hard disk and transfer your data to a reliable alternative hard disk. The repair usually involves the replacement of the read write head mechanism for which a clean air environment is essential.



Hard Drive Rebuild and Recovery:

Computer Science Labs Advanced Data Recovery Service gives you access to unique data recovery methods, procedures and technology capable of recovering data from badly damaged hard disk drives and storage devices considered unacheivable by normal methods. Typically conditions such fire,flood,scratches or a "head crash, will result in the magnetic surface of the hard drive platter being damaged.

Hard Drive Platter Cleaning:

With badly contaminated hard disk drives we are able to clean the surfaces of the recording media and rebuild the hard disk to an operational state that will extract data from the recording areas.

Read Write Head Track Positioning:

With Head Crashes although we cannot recover directly from the damaged or scoured surface areas we are able to recover data recording patterns from the non affected areas. Reading from these areas is normally prohibited by the scanning algorythms used and set-up during manufacture. Here at Computer Science Labs we can manipulate these algorythms and retrieve data from the hard disk.

Hard Drive Tooling Methods:

Our Research and Development department collaborates with The Manchester University to bring new data recovery tools and techniques to the data recovery, computer forensics and IT industry.

Data Recovery Solutions:

Our research and development teams have found new solutions which can fully recover data from drives that are particularly difficult to work with, for example hard disk drives with integrated acoustic spacers assemblies. These spacers make it extremely difficult to implement platter swaps whilst maintaining alignment to read write heads. Many drives that have suffered mechanical failures and needing a platter swap would be deemed unrecoverable using conventional methods and techniques.

Hard Drive Motor Spindle Replacement:

Computer Science Labsí newest development, SERT can recover data from these drives.
SERT is included in our Advanced Data Recovery Service; our technicians will facilitate your recovery by undertaking the mechanical recovery process on your behalf in our certificated laboratory facilities. We operate a high level service and encompass excellent facilities and capabilities.
