Hard Drive Failure Categories and Recovery - Computers - Software

In computing terminology, hard drive is a computer hardware that holds and spins magnetically coated or optical disks in order to read or write information 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.

Stellar Information Systems Limited is the leading organization providing safe and advanced Hard Drive Data Recovery services. Facilitated by Class 100 Clean Rooms, the disk recovery services is available for all SATA, IDE, EIDE, PATA and SCSI hard drives. Stellar offers risk-free services for all Desktop, Laptop, RAID, SAN, NAS and Server hard drives.
