What is Logical and Physical Hard Drive Failure?


The Hard disk drive of your system, be it the PC or laptop whether running on Windows or Mac platforms is the main storage device that stores all the data/files during the long course of its usage. Most HDD failures are not the result of any user activity instead it may crash or fail due to manufacturer defect or aging. Basically, there are two types of hard drive failures i.e. logical failure and physical failure. Let’s learn what is different between logical failure and physical failure of the hard disk drive in detail in this post.

Logical vs Physical hard drive failure

Logical Failure

When the system’s BIOS can detect your hard drive but for some reasons can’t access your data stored on it is referred as a logical failure. Sometimes, Windows may say that no drive is present at all or it may not mount the partition. Usually, logical failure occurs as a result of a bad platter or data corruption.

In a logical failure, the HDD mechanical components and electronic components are all functioning correctly. So you can easily recover failed logical drive without the need to open the hard disk drive. While there are many data recovery tools available in the market; it is important to select the effective and trustworthy software to retrieve your data. Remo Recover tool is available in demo version for free which you can try and preview the recovered data before buying the paid version.

Physical Failure

In a physical failure, the hard drive cannot be recognized because of internal hardware failure or electronic malfunction. When the HDD is physically damaged, you can even hear repetitious grinding or clicking noises. If you hear any unusual sounds from your hard drive, turn off your computer and don’t attempt to use it again until you sent to a recovery center.

The noises you hear could be the result of the head crash which causes complete and permanent data loss. The only way to retrieve data from a physically failed drive is to replace the corrupted hard drive components or just move the data platters to a donor disk where they can be retrieved to a stable destination disk.
