How To Recover Your Data From A Damaged Hard Disk

?

Hard disk drive (often shortened as hard disk, hard drive, or HDD) is an essential hardware component of a computer. It is the main storage unit, where all the programs and data are permanently stored. It is usually large and fixed. Its function is to store a large amount of data. A large part of the operating system, as well as other critical system programs are also stored on the hard disk. A fault with the hard disk could be a major calamity, sometimes requiring Hard Disk Recovery, using data recovery services.

Hard disk working

The hard disk contains a spindle, holding a number of disks called platters. These platters are coated with a magnetic substance. These platters spin under an actuator arm. On the end of the arm, a Read Write (RW) head is attached, which moves over the platter according to the CPU pulse it obtains. Through a read and write mechanism, we can recover data from the hard drive.

Performance:

The performance of the hard disk is measured by the data rate and seek rate. Data rate is the rate of transfer of data, whereas seek rate refers to the time taken by the read-write head to reach the data location on the hard disk.

Data damage:

Broadly, data damages are classified into two types.

1. Non-predictable

2. Predictable

Non-predictable:

Non-predictable data loss is associated with abrupt and unpredictable damages such as

Sudden power surges

Accidental deletion

Accidental formatting

Virus attacks

Predictable:

Predictable data loss occurs due to mechanical wear and aging, which are unavoidable, and take place over time. Such factors have to be monitored regularly by the system administrator, using disk management tools to prevent data loss.

Data loss:

If you need to recover lost data after physical harm to the hard drive, data recovery services can be opted for. Actually, the data remains on your hard drive even though it appears to have been lost. Hence, recovery is possible, provided the right tools are used.
