What is a Hard Drive?:
Commonly known as a hard disk drive (HDD), a hard disk, a hard drive, or a fixed disk. A HDD is an electro-mechanical data storage device that stores and retrieves digital information by use of magnetic storage and one or more rigid rapidly rotating disks called platters, coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile storage, retaining stored data even when powered off. Hard Drives can either be internal or external and connected by a cable.
Common Hard Drive Faults You May Encounter:
When a hard drive fails it can happen for several different reasons. The hard drive might have a software fault such as bad sectors on disk platters, firmware issues that operate the hard drive, operating system faults and file read errors caused by sector problems or viruses or malware. Hard drives have moving parts and also can suffer from mechanical or physical damage such as read/write head damage, motor damage and damage to the disk platters. We have been recovering data in London from hard drives for 14 years. We recover data from all the leading manufacturers. It is important you get your data diagnosed by a Professional Data Recovery Company to maximise your chances of a full file recovery. While it is tempting to use free data recovery software, it is highly likely a professional would be able to retrieve more of your valuable lost files. Below is a list of some of the common faults we receive in:
Physical and Mechanical Hard Drive Issues:
Hard Drive Mechanical or Physical failure is when the parts inside the hard drive fail. Parts inside can fail due to wear and tear but in most cases it is either due to the hard drive getting a knock or a fall or a power surge. Typically parts failing inside the hard drive casing include Read/Write head failure – the read write head read data from the disk platters. Motor Failure – the motor spins the disk platters inside the hard drive casing. Disk Platters – Disk platters can get damage due to motor or read/write head failure. Our Hard Drive Data Recovery Engineers have a high rate of recovering data from mechanical damaged hard drives.
Hard Drives Formatted Accidentally or Through Technical Failure:
Deleting files from hard drives happens on a daily basis. Files and folders can get deleted by accident or on purpose. If the files get deleted on purpose we have a Forensic Data Recovery Department that can recover from this situation. Hard Drives can also get reformatted by mistake or on purpose. We have a data recovery solution for formatted or deleted data. Our Data Recovery Engineers have 14 years experience in recovering data from this type of problem.
Electronic Failure – PCB Failure:
PCB electronic failure is when a hard drive has damage to the electronic components on the hard drive. The electronic components on a hard drive is usually a PCB that sits on the back of the hard drive. The PCB powers up the drive and allows it to work. In a lot of cases this board fails. If you have an electronic failure we can recover your data for you as we have nearly 20,000 hard drive parts in stock.
Hard Drive Firmware Failures:
Hard Drive Firmware is a piece of software that resides on the disk platters or the PCB on the hard drive. The hard drive firmware runs the hard drive and allows it to operate. In a lot of cases the firmware gets corrupted. When this happens your hard disk will not get recognised on boot up process or it will get recognised but by a different name than normal or will display an incorrect capacity of the hard drive. We have a large database of firmware software for all makes and models of hard drives. If you have a firmware failure contact one of our Data Recovery Engineers today.
Hard Drive Issues Caused by Your Operating System:
When a Windows PC, Laptop Mac or Server has an operating system fault the operating system will not load. When this happens it means the sectors on the hard drive where the operating system is installed cannot be read correctly. This is known as bad sectors and is a very common problem with hard drives. We have specialised hardware imaging systems that can force read off the bad sector information to enable a full data recovery.
