Many people have a misconception that external hard drives are different from computer hard drives. Tianwei Data Recovery Center often hears customers say that external hard drives are of poor quality and not as good as the hard drives inside computers. In reality, this is a misunderstanding. For mechanical hard drives, whether they are external, desktop, or laptop drives, the manufacturing process is the same, and their lifespan is almost identical. Generally, the issue is that people tend to be less careful when using external hard drives. For example, carrying them with the data cable directly in a bag can cause the USB port to break easily when subjected to external force. Additionally, since external hard drives are portable, they are more prone to bumps, knocks, or drops during transportation, which can easily lead to damage. Many people also have the habit of not safely ejecting the drive—they simply unplug it after use, often while data is still open. This abrupt disconnection can cause the read/write heads to not return to their proper position or result in firmware loss, leading to data loss or hard drive damage, which is quite common.

    In comparison, desktop or laptop computers are less likely to be moved, bumped, or dropped. They are also typically shut down properly, with very few instances of directly cutting off power. As a result, the probability of damage to internal computer hard drives is lower than that of external hard drives, leading to the mistaken belief that external hard drives are of inferior quality.
