Symptoms of Hard Drive Failure and Data Loss
by K madhav

Knowing the symptoms of the hard drive failure is significant because drive failure is the most common cause of data and information loss on computer systems. If you can recognize the symptoms in advance, you can get prepared for predictable computer system crash and backup your data before it is too late. In all such cases of system crash and hard drive failure, you can retrieve your critical data with the help of hard drive recovery solutions.

The most important thing that you should do to safeguard your data is to create regular backup. In case of system failure, you can easily restore all your lost data from an up-to-date backup. The next important thing is to identify the failure symptoms to be ready to handle data loss. Following are some common signs of disk failure that may help you in recognizing the type of data loss:

o Frozen Computer: While working on your computer, it gets stuck and you can not do anything on it. To overcome this problem, you need to perform hard reboot (using the reset button) of your system. It could be due to virus infection or missing system files. It is a type of logical hard drive failure.
o Missing Files or Partitions: When you bootup your computer and try to access data from it, you may find that some of your critical files and/or hard drive partitions are missing. The problem might be because of factors like accidental deletion or file system corruption.
o System Can Not Detect Hard Drive: If your system is unable to detect the hard drive then the problem could be due to disk controller failure or other similar reasons. It comes under the category of physical data loss.
o Hard Drive Noise: If your system hard drive is making strange scrapping and clicking sounds then the problem could be due to head crash or damage to the actuator arm. This problem occurs due to physical hard drive damage.

Though, data loss is a very critical situation but data recovery is possible even if your hard drive is completely dead. The hard drive recovery solution depends upon the cause of failure. If you are experiencing logical data loss then it can be fixed using hard disk recovery tools. However, in case of physical damage, recovery service is required.
