Hard drive failure can be divided into two categories namely, Logical (software related) and Electro-Mechanical (hardware related) failure.


Logical hard drive failure refers to software issues with your hard drive. The drive is still functioning 100% from a mechanical point of view, but you lost data due to other causes. Here is a list of common reasons for logical failures that we encounter on a daily basis:

  • Formatted hard drive(s). Formatting a hard drive (HDD) involves the operating system preparing a hard drive or partition for initial use. In theory, “deleting” the data that was on the drive / partition. When a drive becomes formatted it normally leaves the data on sector level which is in most cases recoverable by specialised software.
  • Deleted file(s) and/or folder(s). Accidental/intentional deleted directories and/or files.
  • Corrupt partition(s) or partition damage. Partitioning refers to the act of dividing a hard drive into multiple or single logical storage units (partitions) onto which data can be stored. This allows you to have multiple virtual “disks” on one hard drive. Once these partitions become corrupted or damaged operating systems are not able to read the data from the volumes and normally suggest that you format your hard drive.
  • Virus infection. Viruses are malicious software that can delete your data or even corrupt your files. Virus infections are a very common cause of data loss and we strongly suggest you install reliable anti-virus software.
  • Reinstallation or reload. Reinstalling an operating system on your computer involves formatting the hard drive and reloading your operating system’s files onto your hard drive. In most cases once this has been done you will not be able to access the data that was on the drive prior to the format reloading process.


Mechanical (electro-mechanical) hard drive failure refers to physical problems with your hard drive(s). Normally this is caused by a failed hard drive component(s) and / or physical abuse. The following are some mechanical failures we encounter:

  • Hard drive makes a clicking noise. Clicking (clacking, knocking) noises are normally as a result of firmware corruption, broken or damaged reading heads or even platter damage. Typical scenario would be a dropped hard drive.
  • Seized motor. Motor spindle seizure (platter seizing) refers to the platters of a hard drive not being able to spin up and thus the drive is inaccessible. This is also commonly caused by the drive received a hard knock (dropped).
  • Hard drive not spinning / dead hard drive. The drive fails to spin when power is applied (attached) to the hard drive. This is normally caused by electrical damage to the PCB (printed circuit board) in the form of power failure / power surges / spikes / lightning damage.
  • Hard drive spinning up and then down. When power is applied to the drive it starts to spin up and then spins down and repeats. This is normally caused by the platters of the drive not spinning at the correct speed or the hard drive failing to pass its initialisation process.
  • Hard drive contamination. Hard drives are extremely sensitive to contamination. This is one of the reasons we have a class 100 clean room where we can safely open hard drives without the risk of external contamination. Once a drive has been opened in a non-clean environment the risks for data loss are very high. Typical scenarios we encounter are: fingerprints on the surface of the platters and dust contamination.
  • Reading heads crash. (Commonly referred to as hard drive or head crash) This concept refers to the reading heads on a hard drive getting stuck on the surface of the platters or physical damage to the heads of the drive. The damage is normally caused by rough handling or manufacturing failures. Typical scenarios would include: the hard drive being dropped or received a hard knock (impact) and component failure resulting in the heads touching the surface of the platters.
  • Firmware corruption. Each hard drive has its own unique firmware which controls its hardware and without properly functioning firmware will be unable to function. Firmware corruption can be caused by manufacturing problems, self-corruption due to everyday use of the drive or even unskilful firmware updates or incorrect use of professional software (human error).



  • No recovery, no charge, that is:100% data recovery satisfaction guarantee
    • You will not be invoiced should we for some reason not be able to recover the data, or the data recovered not be in a useable condition.
    • We can re-negotiate a price (less than the quoted amount) should some of the data recovered be of use to you with the option to proceed or not.
  • 100% satisfaction guaranteed:
    • We will do everything possible to rectify the recovery or refund the recovery charges (or a portion thereof) should we not be able to solve any valid issues with the recovered data.
    • The above is not applicable should the wrong media be sent to us for data recovery.




* Your choice would typically be based on the urgency of the data recovery vs. how much you can afford to spend on the successful recovery of your data.
