Categories of Hard Drive Failure and its Recovery

Hard drive is defined as a computer hardware that holds and spins magnetically coated disks in order to read and write data on it. The data thus stored is persisted by system even when it is turned off. The hard drive is composed of several mechanical and electronic components. For this reason, this storage media gets gradual or steep break-down while it is working and performing. A hard drive failure is the most popular term used when a hard drive stops working. It primarily occurs when one or more physical components of hard drive fails and stops working as expected. As the general solution, you should replace such failed hard drive and use your recent data backup to restore the information. However, while the valid backup is unavailable, you need to consult a hard drive recovery technician that could assist you to recover lost data from a physically crashed drive.

Typically, hard drive failure can be categorized in two basic classes: Gradual Hard Drive Failure and Sudden Hard Drive Failure

Gradual Hard Drive Failure

Such failures occur due to surface wear, slow breakdown of hard disk components and bad sectors on surface. You can recognize a failing hard drive by any of these signs:

1. Operating system errors and crashes

2. S.M.A.R.T errors indicating that hard drive failure is imminent

3. Chkdsk errors

4. Data starts vanishing

5. Slow system performance

It is recommended to backup all the stored data if you observe any of the aforementioned symptoms.

Sudden Hard Drive Failure

Sudden hard drive failure characteristically represents the condition when you cannot access the data anymore. The hard drive appears almost dead. You might infer a sudden hard drive failure with any of the below symptoms:

a. Hard drive is not recognized by CMOS setup

b. Hard drive fails in POST check and operating system cannot see it

c. No or repetitive hard drive seek activity sound. The hard drive might emit clicking or ticking sounds.

Such failed hard drives need to be diagnosed using high-tech recovery techniques, performed through hard drive data recovery services. Since hard drive internals are sensitive to dust-like particles, Hard Drive Recovery is provided by opening them in safe Clean Room surroundings.

Windows File Loss Due to Missing Configuration and System Files

Upgrading to the latest or later version of an operating system is a common practice for Microsoft Windows users. Up-gradation is generally performed to take advantages of added features in the newer version. Though, you upgrade the operating system for good, but in some situations it might prove damaging for your system. Sometimes, after upgrading the operating system, your computer might not start and may make all of your mission critical and valuable files inaccessible. This behavior of Microsoft Windows computer results into file loss and require windows hard drive recovery to be resolved.


After upgrading the Windows operating system, when you attempt to start your computer, you might come across the below given error message:


“C:\Winnt\System32\autoexec.nt The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application”

When this error message occurs, you have to close all the applications that you are trying to open.


Grounds of the issue


You might encounter this problem due to missing or corrupt Config.nt, Autoexec.nt and Command.com files of Microsoft Windows operating system.

Hard Disk Error Management and Recovery

Sometimes you don't realize that it is normal for a hard disk to face errors during reading, as part of its regular operation. As hard disks are pushed to the limits of technology , with tracks and sectors spaced closer together, weaker signals used to prevent interference and faster spin rates produced by the spindle motor the chances of an error happening while reading the disk go up noticeably. In fact, the state of technology has advanced to the point where it is not practical to even try to avoid them.

Having actual errors appear to you while using the hard disk is intolerable, since you count on your disk reproducing the data you store on it reliably for a period of years. Hard disk manufacturers know how important this is and so incorporate special techniques that allow them to detect and correct hard disk errors. This allows them to make faster, higher-capacity drives that seems to the user to be error-free. The more the technology for storing data is pushed, the more sophisticated the error correction protocols must be to maintain the same level of reliability.

Making a drive that actually produced read errors infrequently enough that error detection and correction wasn't necessary, would mean greatly reducing performance and capacity. This is sort of like touch-typing there's a school of thought that says "if you aren't making any mistakes at all, you're going too slow". If correcting mistakes is easy, as it is with a word-processor, it's better to type 100 words per minute and correct an error or two, than type 75 words per minute error-free. As long as the errors are detectable and correctable, and they don't occur too often, it's better to plan for them, and then tolerate and deal with them, than to be too conservative in order to eliminate them.
