When your computer recognizes your hard drive, but you’re unable to access the files stored on it or boot into the operating system, it often means that the file system has been damaged. Solution: Hard Drive Data Recovery Service #4 Hard Drive Inaccessible A hard drive recovery service center with a well-equipped, dust-free lab should be able to solve this problem, for a hefty price. Because the gap between the hard drive heads and platters is so small, they can literally stick to each other. This can happen because of something that’s known as stiction. A scratched platter usually means an irreversible data loss.Ī hard drive may make beeping sounds when it’s trying to spin the platters, but it’s unable to do so. The head may be stuck on a platter, scratching it violently as the disk controller attempts to move it. They occur when a hard drive is unable to return the rear/write head to its home position. Solution: Hard Drive Data Recovery Service #3 Clicking or Beeping NoisesĬlicking sounds are often an indication of serious hard drive damage. Usually, it’s enough to replace the printed circuit board (PCB), which can be done in a normal environment without opening the hard drive enclosure. A voltage spike may cause these diodes to blow, making the hard drive seem as if it were dead and all data were lost. Inside the hard drive are special diodes that act as fuses. This often happens after a sudden voltage spike.

Solution: Use Hard Drive Data Recovery Software #2 Hard Drive Isn’t Spinning In the next chapter, we recommend our top 10 favorite tools for recovering external hard drives. There are many capable data recovery tools that you can use to recover external hard drives after a software data loss without any expert knowledge. The one thing that most cases of software data loss have in common is recoverability. Every day, important files are lost because someone decided to empty the Recycle Bin without first checking whether it doesn’t contain something important. Software data loss is most commonly caused by badly written software applications or unfortunate user errors.
Hard drive failures can be categorized into two broad categories: software failures and hardware failures. Diagnosing Common Types of Hard Drive Failure One of these electronic components is a small memory chip that stores the firmware, which is permanent software that provides the necessary instructions for how the hard drive communicates with the other computer hardware. Each platter has its own reading head, which hovers several nanometers above the platter’s surface, writing converting strings of bits onto the disk using electrical current fed through an electromagnet.Īttached to the bottom of the hard drive is a circuit board, which houses the main controller chip as well as many other electronic components that control the operation of the headers. These grains cover circular platters that spin at 7,200 rpm, at least on consumer drives. Inside every external hard drive is an assortment of sensitive components that record data as a magnetic pattern formed by groups of magnetized metal grains. But before we get to the most common causes of a hard drive failure, we first need to touch upon how hard drives work.

How many people know how to recover files from external hard drives and how many would simply panic, not knowing what to do? If you know how to recover data from external hard drives, you have much better chances to prevent the worst from happening and turn what could be a disastrous situation around.
Because of their ubiquitous nature, we have come to rely on them so much that we seldom consider just how fragile external hard drives are. They allow us to carry terabytes of data everywhere we go, they can be easily shared among many devices, and their installation could hardly be any simpler. The convenience of external hard drives is undeniable.
