The cause of hard drive crash might vary in every case and the most common hard drive crash factors are:
- frequent power spikes
- operating system malfunction
- system data structure corruption
- read/write head crash
- disk mechanical failure, and
- natural disasters.
Damage to hard drive is divided into two major categories:
Logical Hard Drive CrashIn case of logical failure or crash, your hard drive physically remains intact. Only the data structures of the drive, such as file system, become faulty. Damage to computer file system does not let the operating system to mount the hard drive and access data from it. Other causes that may cause logical data loss include, accidental deletion, operating system corruption, MBR corruption, hard drive formatting, virus infection, and more.
Valuable data is recoverable after logical failure in a quick and easy way through third-party applications. These tools are known as Data Recovery Software. They are particularly designed to carry out in-depth scan of entire hard drive through, using advanced scanning techniques. Such utilities are completely easy to use with simple graphical user interface.
Physical Hard Drive CrashPhysical damage is the leading cause of premature hard drive failure. Such kind of damage occurs after failure of the mechanical/internal components of hard drive. The reasons may be read/write head crash, power spikes, short circuit, and natural disasters.
When a hard drive is powered off, most read-write heads park on a special area of the platter that protects the heads and platter from damage. When a hard drive is powered on, the heads are designed to float across the platter surface. If a hard drive suffers any physical damage during this time (such as bumping or jostling), it is likely to suffer a head crash. In such circumstances, you need to find a reliable and experienced Data Recovery Service provider company to repair or replace damaged hard drive components and get your precious data recovered.
Symptoms of hard disk crash- Computer will not boot
- Error messages like "No Fixed Disk Present" or "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER"
- Blue or black screen after power up (commonly referred as Blue Screen of Death)
- Clicking/ticking/humming/grinding and crunching noises coming from the drive
- System often reboots, restarts, hangs or freezes
- "Drive not formatted" and “Operating system not found”, messages
The problem can only get worse!1. Pressing the start button repeatedly to boot a computer is a fatal mistake that might kill a damaged drive. The drive might have suffered a head crash with the read-write head touching the rotating platter and causing damage to the magnetic media in the platter surface. Repeated attempts to start the disk result in increasing the damage to the platter surface.
2. Pulling out the hard drive or hitting the computer in a hope to jerk it to recovery can cause damage to the many minuscule magnetized pieces of the drive, making a damaged disk inoperative.
Computer users need to avoid these knee jerk reactions and take recourse to hard drive recovery tools and techniques.
Argh, it's too late for me!! Sadly, I pressed the start button repeatedly and hit the laptop to jerk it to recovery in my many attempts to boot up my stupid laptop...
Sent my hard disk to a data recovery company this morning for evaluation... The guy just advised that it is likely that the hard disk suffered a head crash and further analysis is to be done to determine if data is recoverable... Cost for data recovery for physical hard drive damage is pretty high man, from $600 - $2,000!! Gosh...
My whole year worth of photos for 2010 and work/personal documents for the past 5 years are gone!... forever!! **Whine, whine, whine
My advice to you: Go and back up your data into an external hard disk or burn into DVDs NOW
