The convenience of external hard drives is undeniable. 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. 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.

best external hard drive recovery software

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.

Drawing on over 30 years of experience, including a significant tenure at IBM as a Backup and Recovery Expert, I’ve encountered nearly every form of hard drive failure imaginable. Through this article, I’ll share insights from firsthand testing of recovery tools, guiding you through common issues and effective solutions for external hard drive data recovery.

Before You Perform External Hard Drive Data Recovery

Before rushing to download and use any data recovery tool you come across, it’s important to step back and understand the common reasons behind external hard drive failures. Using an inappropriate tool can worsen your situation, leading to permanent data loss. It’s essential to start with a basic understanding of how hard drives operate and the typical causes of their failure.

At the first sign of trouble with your external hard drive, the most critical action to take is to stop using it immediately. Continuing to use the drive can result in data being overwritten, which is often irreversible and can significantly reduce the chances of a successful recovery.

Diagnosing Common Types of Hard Drive Failure

Hard drive failures can be categorized into two broad categories: software failures and hardware failures.

#1 Logical Issues

hard drive recovery Logical issues with external hard drives are primarily related to problems within the file system or corrupted data that prevent access to the stored information. These problems can arise from a variety of sources including abrupt disconnection of the drive during data transfer, power surges, or simply because of faulty file system operations.

Recovering from logical issues often requires specialized data recovery software capable of navigating the complexities of file systems to restore access to the data. Fortunately, these types of problems have a high recovery rate if addressed promptly, using the right tools before any new data is written to the drive, potentially overwriting the lost files.

#2 Hard Drive Isn’t Spinning

hard drive data recovery This often happens after a sudden voltage spike. Inside the hard drive are special diodes that act as fuses. A voltage spike may cause these diodes to blow, making the hard drive seem as if it were dead and all data were lost. 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.

#3 Clicking or Beeping Noises

Clicking or Beeping Noises Clicking sounds are often an indication of serious hard drive damage. They occur when a hard drive is unable to return the rear/write head to its home position. The head may be stuck on a platter, scratching it violently as the disk controller attempts to move it. A scratched platter usually means an irreversible data loss.

A hard drive may make beeping sounds when it’s trying to spin the platters, but it’s unable to do so. This can happen because of something that’s known as stiction. Because the gap between the hard drive heads and platters is so small, they can literally stick to each other. A hard drive recovery service center with a well-equipped, dust-free lab should be able to solve this problem, for a hefty price.

#4 Hard Drive Inaccessible

Hard Drive Inaccessible 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. The damage can be extremely localized, perhaps affecting only the boot sector, or it can be widespread. The good news is that data recovery tools such as Disk Drill can easily recover data from inaccessible hard drives and help you spot growing file corruption before it gets out of hand.

#5 Hard Drive Not Detected

Hard Drive Not Detected When your computer is unable to detect a hard drive which you know is otherwise in a good working order, it could mean that the hard drive is not compatible with your motherboard. This shouldn’t happen when dealing with regular desktop hard drives connected to regular desktop computers, but it can happen when dealing with exotic server equipment or older hardware.

#6 Malware Infection

Malware Infection During the Windows XP era, there were many computer viruses designed to inflict as much damage as possible by deleting the data stored on hard drives. Fortunately, this type of malware, short for malicious software, is much less common today, but malware still remains a huge threat. In recent years, ransomware has emerged as one of the biggest causes of data loss, encrypting important data and demanding a hefty ransom of its decryption.

#7 Data Corruption

Data Corruption Software programmers still make many of the same mistakes as they did several years ago. The same, of course, also applies to computer users. As such, it’s fairly common for files to suddenly become corrupted and, as a result, unreadable. In some cases, corrupted files can be repaired using readily available and easily applicable tools and techniques, but that’s not always the case.

#8 Physical Hard Drive Destruction

Physical Hard Drive Destruction Even the latest and greatest hard drives are not immune to physical damage. While modern SSDs are far more reliable than their traditional spinning counterparts because they don’t have any moving parts, it still takes just one blown transistor for a perfectly healthy hard drive to turn into a useless brick. Because DIY repairs of physically damaged hard drives rarely deliver the desired results, it’s best to contact professionals right away and hope for the best.

How to Recover Data from an External Hard Drive

Let’s take a closer look at how to recover files from a hard drive that has suffered one of the common types of hard drive failure described in the previous section of this article. As long as you select the right recovery method, there’s a good chance that you’ll be able to reunite with your files.

Option 1: Try a Hard Drive Data Recovery Software

Data recovery software is your best bet when it comes to recovering data from logically damaged hard drives. In this article, we list our top 11 favorite HDD recovery tools, and we encourage you to make your own choice. For the purposes of this recovery guide, we are going to focus only on the number one hard drive recovery tool we know: Disk Drill.

Option 2: Hard Drive Data Recovery Service

Unfortunately, not all data loss situations can be addressed at home with DIY data recovery software. In some cases, such as when dealing with physically damaged hard drives, it’s necessary to contact a data recovery service center like SalvageData and let professionals with state-of-the-art equipment and plenty of experience take care of the recovery for you.

Most data recovery centers have a similar workflow:

  1. You initiate a work order.
  2. Pack and ship your media.
  3. Receive an expert estimate.
  4. Approve the price quote.
  5. Wait until your data is recovered and securely delivered to you on a DVD, a flash drive, or an external hard drive.

Contrary to what many people believe, professional data recovery doesn’t cost an arm and a leg. In fact, most legitimate companies charge only for recovered data and offer, so you don’t need to worry about spending hundreds of dollars and achieving nothing at all.

Option 3: Try Manual HDD Recovery Fixes

Especially when dealing with data loss caused by file system corruption, it’s often possible to recover lost data using manual HDD recovery fixes. We’ve described many effective fixes in the past in relation to SD card and Mac hard drive recovery, so we won’t list them all here. Instead, here are just three manual HDD recovery fixes that are most likely to deliver the desired results:

Fix 1: CHKDSK Command

All Windows computers come with a utility called CHKDSK, whose purpose is to verify the file system integrity of a volume and attempt to fix logical file system errors. Even though CHKDSK doesn’t have a graphical user interface, using it is surprisingly simple:

  1. Type “cmd” in the search box on the taskbar and select Run as administrator.
  2. Enter the following command and press Enter: chkdsk X: /f (make sure to replace X with the letter assigned to the HDD you want to fix)chkdsk command to recover data from an external drive
  3. Wait for CHKDSK to finish.

Fix 2: First Aid in Disk Utility

Mac users can’t use CHKDSK to fix corrupted hard drives, but they can use something even better: the First Aid feature in Disk Utility. As its name suggests, the purpose of the First Aid feature is to diagnose and fix storage devices that are not working correctly. Since it has a nice user interface, it’s fairly self-explanatory, but here’s what you need to do in a nutshell:

  1. Go to Finder > Application > Utilities and launch Disk Utility.
  2. Select the hard drive you want to repair from the list on the left and click the First Aid button.First Aid in Disk Utility
  3. Confirm that you want First Aid to check the partition for errors.

Fix 3: Driver Reinstallation

Even pros sometimes make a mistake and that also applies to the software developers responsible for hard drive drivers. A faulty or corrupted driver can make your HDD unusable or inaccessible, but reinstalling it takes just a few minutes:

  1. Type “device manager” in the search on the taskbar and select the Device Manager option.
  2. Go through the available categories and look for your external HDD. You will most likely find it under Portable Devices.
  3. Right-click the SD card and select Uninstall device.Driver Reinstallation
  4. Restart your computer.
  5. Wait for the right driver to be automatically reinstalled.

Tips for Increasing Your Hard Drive Data Recovery Success Rate

The hard drive data recovery software applications listed in this article can deliver great results, saving the day when dealing with many different kinds of hard drive failure. As effective as they are, you can increase your hard drive recovery success rate even more by following the few simple tips below:

  • Don’t delay the recovery process: The sooner you install hard drive data recovery software on your computer and use it to scan the storage device on which the lost files were located, the more likely you are to get your files back.
  • Use the best software available: Not all hard disk recovery applications perform the same. Some support only a few file formats, while others can recover just about any file and sometimes even repair files that have been corrupted. That’s why you need to do your research and use the best software available.
  • Minimize the risk of overwriting: Permanently deleted files can be recovered only while they’re still physically present on the hard drive. Once they become overwritten, their recovery stops being possible. As such, you should do as much as you can to minimize the risk of overwriting, like unplugging the hard drive in question until you’re ready to begin the recovery process.

These three simple tips can be the difference between partial data recovery and complete data recovery. Of course, the best way to ensure 100% successful recovery is to back up all important files on a regular basis and keep the backups someplace safe. That way, you’ll be able to recover even after experiencing a total hard drive failure.


Yes, it’s possible to recover an external hard drive. Even if you’ve formatted the hard drive or if it is damaged or corrupted, there is a high possibility of successfully restoring all of the missing files.

It depends on the severity of the issue and your external hard drive condition. If it is not physically or logically damaged, you should be able to recover the files by yourself with the help of specialized data recovery software. Otherwise, you’ll need to send your hard drive to an in-lab professional service center, which will cost you between $300 – $3000.

If you want to recover files from an external hard drive but it is not showing up on your computer, you can use a third-party data recovery tool to complete the recovery. Follow these steps to recover an undetected external hard drive:

  1. Download and install Disk Drill.
  2. Launch the application.
  3. Connect the external hard drive to your computer.
  4. Choose your external hard drive from the list.
  5. Click the Search for lost data button to scan the drive.
  6. Click Review found items to view the files.
  7. Choose the files that you wish to restore and click Recover.
