Hard Disk Drive Failure
There can be many causes of hard drive failure. To successfully recover the data from a faulty hard disk drive it is first necessary to correctly diagnose the problem(s) it is suffering from and repair the hard drive.
Hard disk drive failure happens in 4 main ways:
1. MECHANICAL
Failure Symptoms:
– The hard drive may make a regular clicking noise when it is first powered on. This will last for approximately 20 seconds before the disk powers down.
– The hard drive may beep when first powered on.
– The drive will not be recognised by the computer
– Listen to an audio file of a hard disk drive with a mechanical fault
– Watch some YouTube footage of several types of hard drive failure
Causes:
– The hard drive has received a knock: for example, it may have been dropped, or if it is in a laptop, the laptop may have received a bang.
– Mechanical failure is not exclusive to hard drives receiving knocks, hard drives can fail at any time – especially the older they get.
2. LOGICAL
Failure Symptoms:
– Files and Folders will not open or have become inaccessible
– Files and Folders will not copy correctly – often CRC (Cylical Redundancy Check) errors will be reported
– Files and Folders may have been deleted or overwritten
Causes:
– Areas of the hard drive may not be readable due to the development of bad sectors.
– Data structures on the hard drive may have been corrupted due to (eg) the disk not being ejected from the system correctly.
3. ELECTRONIC
Failure Symptoms:
– The drive will not spin when it is powered on
– Sometimes the hard drive will get very hot
– It will not be recognised by the computer
Causes:
– A power surge has caused damage to the drive
– The wrong power cable has been plugged in.
4. FIRMWARE
Failure Symptoms:
– The drive will be recognised incorrectly by the computer
– Often the capacity of the drive is also reported incorrectly
Causes:
– The firmware (or ‘microcode’) that runs the drive has become corrupted. Often this is a result of software bugs that exist in the firmware.
