The findings above reflect three things. First, that manufacturing, shipping, and initial use of hard drives contribute to its failure during its first couple of years. Second, that usage increases the probability of a hard drive failure in the last couple of years of its existence. And third, that hard drives relatively last for at least three years. So what causes the failure? We have a few listed below.
Mechanical FailureIf the parts that make the hard drive functional are damaged, the failure is mechanical. This includes head crash or the breakdown of the different “discs” that makes data storage and retrieval possible. Mechanical failure is often detectable, especially in desktops since you’ll hear a strange sound like grinding, scraping, clanking, beeping, or clicking. If such problem goes undetected, data lost is often unrecoverable through ordinary means until taken to a cleanroom.
Hard drives contain a common part called the circuit board. The circuit board is responsible for making the components of the computer and the hard drive communicate in a synchronized manner. The circuit board is also where the read/write heads (RW) are located. Often, the cause of electronic failure in hard drives is overheating. Keeping your hard drive in a well-ventilated area is necessary. Also, don’t keep the hard drive exposed under any conductors like metals and even under the sun.
Logical failures come in two forms: corrupted information and media fatigue. First, corrupted information pertains to the information stored on the hard drive. This can happen if accidental formatting occurs within the drive, if important critical files or important keys are deleted, or if the files get infected by a virus or a malware.
Media fatigue relates to usage over time. Logically, as in all devices, the more we continue to “wear” them, the greater “tear” they experience. So physical deterioration also happens not only on the external properties of the hard drive, but also the internal “machines” or parts that make it work. This occurs most especially in the platters or discs that continuously spin when you store, retrieve, or edit information.In summary, there are several factors in play that affect the longevity of hard drives. That means proper care is still needed in order for you to not affect the longevity of your device. And because the internal parts are something that you don’t have control over, it is best to save your information on various devices or even on the cloud. If you lost date, you can send your device over to companies who offer data recovery services.
