If you are experiencing the following problems, your hard drive may be defective. These include Spindle motor malfunction, damaged recording surface, and excessive vibration during quick motions, and file system corruption. If you are experiencing any of these symptoms, it is time to visit a technician. It would help if you did not try to diagnose your hard drive yourself. Taking the time to repair the device will ensure a long-lasting backup. Visit this link to know the external hard drive price in UAE before buying.
Spindle motor malfunction:
There are several common reasons why an external hard drive gets damaged. Spindle motor malfunction is one of them. When the motor stops working, the platters cannot spin. The data on the disk cannot be accessed. Spindle motor malfunction can be fixed by swapping the platters with the new drive. However, the old one will not spin properly after the swapped disk. You need to repair the PCB, and the read/write assembly to fix this issue.
Damaged recording surface:
External hard drives may not be as durable as their internal counterparts despite their name. Hard drives are prone to failure due to various reasons, including physical shock, which can damage heads and platters. Faults associated with circuit boards account for 18% of drive failures, typically caused by moisture or static electricity. Stopped read/write head armatures are another potential cause of drive failure. Likewise, drives can be prone to mechanical failure, traction, or a combination of all three.
Excessive vibration on quick motions:
An external hard drive can suffer from excessive vibration when used in a rapid motion, such as when a person walks across it. Such vibration can damage an HDD if it occurs incorrectly and at an angle. A computer must be placed on a flat surface to avoid causing it to suffer from excessive vibration. External hard drives with power supplies can also produce a faint humming sound, which may be due to static friction.
File system corruption:
When an external hard drive is used for backup purposes, it can suffer from file system corruption. This problem can occur due to various reasons, including improper procedures or power surges. If you suspect your external hard drive is corrupted, try to backup your important files on a USB drive. One way to check whether a file is corrupted is to look at its size. If the file appears smaller or wider than its previous version, it’s most likely corrupted.
