How To Recover Files From Damaged External Hard Drive – The convenience of external hard drives is undeniable. They allow us to carry terabytes of data with us wherever we go, can be easily shared between multiple devices, and are very easy to install. Because of their ubiquitous nature, we rely on them so much that we rarely think about how fragile external hard drives can be.
How many people know how to recover files from an external hard drive and how many panic not knowing what to do? If you know how to recover data from an external hard drive, you have a much better chance of preventing the worst and reversing a potentially catastrophic situation.
How To Recover Files From Damaged External Hard Drive
The purpose of this article is to explain common hard drive problems and the different ways to solve them using external hard drive recovery software.
Drive Is Not Accessible The Parameter Is Incorrect On External Hdd
Before you go online and download your first data recovery tool, you’re going to stop and let us explain some of the most common causes of hard drive failure to help you successfully solve the underlying problem.
Using the wrong hard drive recovery tool can make your problem worse and lose your ability to recover data. But before we get into the most common causes of hard drive failure, we first need to look at how hard drives work.
Inside each external hard drive are various sensitive components that record data in the form of magnetic patterns formed by groups of magnetized metal grains. These grains cover a circular disc that spins at 7,200 rpm, at least on consumer discs. Each platter has its own read head that hovers a few nanometers above the platter’s surface, writing a string of bit conversions to disk using an electric current fed through an electromagnet.
Attached to the bottom of the hard drive is a printed circuit board that houses the main controller chip and a host of other electronic components that control the operation of the headers. One of these electronic components is a small memory chip that stores firmware, which is a permanent piece of software that provides the necessary instructions for how the hard drive interacts with the rest of the computer’s hardware.
How To Repair A Dead Hard Disk Drive To Recover Data
Software data loss is most often due to poorly written software applications or unfortunate user error. Every day, important files are lost because someone decides to empty the recycle bin without making sure there is nothing important in it.
One thing that most cases of software loss have in common is recovery. There are many effective data recovery tools that can be used to recover external hard drives after software loss without expert knowledge. In the next section, we recommend the 11 best external hard drive recovery tools.
This often happens after a sudden voltage surge. Inside the hard disk there is a special diode that acts as a fuse. A voltage spike can cause these diodes to blow out, causing the hard drive to appear to be dead and all data lost. It is usually sufficient to replace the printed circuit board (PCB), which can be done under normal conditions without opening the hard drive cover.
A clicking sound often indicates a serious hard drive failure. These occur when the hard drive fails to return the rear/recording head to its original position. The head can get stuck in the platter, scratching it badly when the disc controller tries to move it. A scratched tablet usually means permanent data loss.
Solved] How To Fix Corrupted Hard Drive Without Formatting
The hard drive may beep when it tries to spin the platter but can’t. This can happen because of something known as stiction. Because the gap between the hard drive heads and the platters is so small, they can actually stick to each other. A hard drive recovery service center with a well-equipped, dust-free lab should solve this problem at a great price.
If your computer recognizes your hard drive, but you can’t access the files stored on it or load the operating system, it often means that the file system is corrupted. The damage can be very localized, perhaps affecting only the boot sector, or it can be widespread. The good news is that a data recovery tool like Disk Drill can easily recover data from an inaccessible hard drive and help you spot growing file corruption before it gets out of hand.
If your computer cannot detect a hard drive that you know is working properly, it may mean that the hard drive is incompatible with your motherboard. This shouldn’t happen with typical desktop hard drives attached to typical desktop computers, but it can happen with exotic server hardware or older hardware.
During the Windows XP era, there were many computer viruses designed to cause as much damage as possible by deleting data stored on hard drives. Fortunately, this type of malware, short for malware, is much less common today, but remains a serious threat. In recent years, ransomware has become one of the biggest causes of data loss, encrypting sensitive data and demanding large ransoms to decrypt it.
Best Data Recovery Apps For Mac
Programmers are still making many of the same mistakes as they were a few years ago. The same, of course, applies to computer users. So, quite often the files suddenly get corrupted and as a result become unreadable. In some cases, damaged files can be recovered with affordable and easy-to-use tools and techniques, but this is not always the case.
Even the newest and best hard drives are not immune to physical damage. While modern solid state drives are much more reliable than traditional spinning solid state drives because they have no moving parts, it still only takes one transistor to blow and turn a perfectly healthy hard drive into a useless brick. Since DIY repair of physically damaged hard drives rarely yields the desired results, it’s better to call a professional and hope for the best.
Let’s take a closer look at how to recover files from a hard drive that has experienced one of the common types of hard drive failure described in the previous section of this article. As long as you choose the right recovery method, there’s a good chance you’ll be able to recover your files.
Data recovery software is your best choice for recovering data from a logically damaged hard drive. In this article, we’ve listed 11 of our favorite hard drive recovery tools, and we encourage you to make your choice. For the purposes of this recovery guide, we’ll focus exclusively on the number one hard drive recovery tool we know: Disk Drill.
How To Use An External Hard Drive On Windows And Mac?
Disk Drill works on Windows and macOS, and the free version allows you to view an unlimited number of lost files. Because Disk Drill has a modern and intuitive user interface, it is suitable even for novice users whose understanding of data recovery is limited by the information provided in this article.
As you can see, data recovery with Disk Drill consists of three simple steps, so you have nothing to fear, especially when you consider that Disk Drill can view all deleted data for free.
Unfortunately, not all data loss situations can be solved at home with do-it-yourself data recovery software. In some cases, such as when you are dealing with a physically damaged hard drive, you will need to contact a data recovery service center like SalvageData and let professionals with advanced equipment and extensive experience perform the recovery for you.
Contrary to what many people believe, professional data recovery is not expensive. In fact, most legitimate companies only charge for data and offer recovery, so you don’t have to worry about spending hundreds of dollars and getting nothing at all.
Worst Reasons Of Hard Disk Failure And Data Recovery Solutions
Especially in the case of data loss caused by file system corruption, it is often possible to recover lost data using manual hard drive recovery. We’ve covered a lot of effective Mac SD card and hard drive fixes in the past, so we won’t list them all here. Instead, here are just three manual hard drive recovery fixes that are likely to produce the desired results:
All Windows computers come with a utility called CHKDSK whose purpose is to check the integrity of a volume’s file system and try to fix logical file system errors. Although CHKDSK does not have a graphical user interface, it is very easy to use:
Mac users can’t use CHKDSK to repair a damaged hard drive, but they can use something better: Disk Utility’s First Aid feature. As the name suggests, the purpose of the First Aid feature is to diagnose and fix an error that isn’t working properly. Since it has a nice user interface, it’s self-explanatory, but here’s what you need to do in a nutshell:
Even professionals make mistakes sometimes, and this also applies to software developers responsible for hard disk drivers. Damaged or corrupted drivers can make your hard drive unusable or
