Computer systems are prone to data loss with relative regularity, often precisely because they are always becoming faster and more complex. Data loss can take the form of crashes, corrupted hard disks and server failures.
A professional service will swiftly send a courier to collect the failed hard disk. Back at the laboratory, technicians will mount a close inspection of the hard drive in order to provide the client with an estimate of the severity of the problem, the length of time that it will take to fix and the cost of data recovery.
A timescale for data recovery will be agreed with the client before the hard disk is repaired and data restructures restored, the raw data is extracted and the file listings are analysed. Data files are usually returned on new media, such as DVDs or an external hard drive.
The length of time that it can take to recover data from a crashed system depends upon the nature of the crash. The failure can be due to something relatively simple, such as a crash of the computer’s operating system or simple human error. However, there can be more complex reasons for a crash, such as attacks by hackers or infection by computer viruses or malware. Most seriously of all, hard drives can become physically damaged or corrupted.
A simple problem with the operating system usually means that all the technician has to do is use their expertise to extract the data and copy it on to a new form of media, such as another hard drive or disk.
In the event of a faulty or corrupt hard drive, the technicians will have to take more drastic steps, such as making repairs to the file directory itself or by attempting to retrieve the data with the use of specialised software.
In this scenario, the technician will use a powerful microscope to examine the hard drive itself for signs of damage. A similar analysis will be carried out on the system’s electronics and electrical systems, such as its power source, servos and interfaces. The technician will carry out the same level of examination for the drive’s magnetic media, such as its read/write heads.
If the examination reveals faults or complete breakdown, the offending components will be repaired or completely replaced, allowing the disk itself to be cleaned under safe, clean lab conditions, before being upgraded and reprogrammed.
The disk will now be functional once more, whereupon the all-important data will be able to be accessed and extracted. Professional data recovery services have special proprietary programs to read any data stored on the disk’s magnetic platters.
When the data is extracted, it will be transferred to the lab’s own secure servers, before being carefully checked for errors and gaps. If any bad sectors are found, they will be repaired in consultation with the client.(Olivia Wilson)
