Ever heard that sinking feeling when you realize you’ve accidentally deleted or wiped important files from your external hard drive?
Don’t panic! While it may seem like they’re gone forever, the good news is that recovering data from external hard drives is often possible, even after formatting or logical damage. Thanks to how modern operating systems handle file deletion, the files are often still physically present, just waiting to be rescued. This is where data recovery software comes in.
This article will guide you through the detailed process of external hard drive recovery, showing you the tools and steps to bring your lost files back.
Wait, Are You Suggesting My External Hard Drive Can Be Recovered?
Yes, recovering files lost due to deletion, formatting, or even corruption on an external hard drive is often possible. This is because, as we discussed earlier, operating systems don’t actually erase data when you delete it.
The key is to stop using the external hard drive as soon as you suspect you have lost data. You need to prevent the operating system from overwriting the deleted items with new information. Unplug the external drive and don’t use it again until you are ready to perform the data recovery.
When you delete a file on a Windows system, logical access to the data is removed but the data remains physically on the disk. The space occupied by the deleted item is marked as available for future use by the operating system. Eventually, that space will be reused as new data is saved to the disk.
Until the original data is overwritten, data recovery software can ‘revive’ it. At the file system level, such software scans the directory entries of deleted files and pieces lost files together. Additionally, it recognizes file signatures, which are unique patterns within file headers, to identify remnant data fragments and reconstruct them into usable files.
Here’s an interesting statistic for you:
Our internal statistics and feedback from our users, as well as statistics from services like Google Ads, all point to one thing: users are most interested in recovering deleted data, data from formatted devices, and data from logically corrupted devices. Thankfully, data recovery software is particularly effective in all of these scenarios. So, without further ado, let’s jump into the recovery guide.

Still curious about Disk Drill? We’ve prepared even more comprehensive review of its functionality and scanning results, along with an analysis of its safety.
If Disk Drill didn’t work out for you, consider exploring alternative programs. We’ve compiled a short list of other external hard disk data recovery software worth examining:
- R-Studio: Excellent for advanced users, offering a comprehensive toolkit for data recovery professionals. However, the Trial version’s restrictive 256 KB file size limit and overall complexity might deter beginners.
- PhotoRec/TestDisk: These open-source gems work in tandem. TestDisk specializes in repairing external hard drive partitions, while PhotoRec recovers deleted data from formatted/corrupted drives. While completely free, the downside is that recovered data lacks original names and folder structure, as it’s retrieved purely from file signatures.
- Recuva: This popular Windows data recovery option might not blow you away with its results, often falling short in both file system and signature-based scans. However, it’s completely free and user-friendly, making it a decent last resort.
Be Aware of Losing Data From Your External Hard Disk
There are many reasons that your external hard drive can experience data loss. Some of the most common are:
- 🛑 Human error – This is by far the most common reason for data loss. It can occur through accidentally deleting files or formatting disks. Perhaps you are unfamiliar with the Windows cmd command and accidentally ran a script that deleted a bunch of files. You might realize it a split second after executing the command, but the damage is done.
- 😔 Faulty upgrades – Occasionally a faulty system or application upgrade can impact your system. If an external hard drive was attached to your machine during the upgrade, it could have been negatively impacted and you may have lost some data from it.
- ⚡ Power surges – A power spike can cause damage to your drive and result in a broken storage device that requires data recovery software in order to recover its data. The drive can appear dead after being subjected to an extreme power surge.
- 🔥 Extreme conditions – Leaving an external hard drive in a hot car or other location where it will be exposed to high temperatures can cause damage to the disk. Similar results will occur if you expose the device to high humidity or moisture.
IMPORTANT POINT: These are just some of the causes of data loss that may confront you. A critical point to remember is to immediately stop using the external storage device as soon as you suspect data loss has occurred. Failure to follow this guidance can lead to the deleted data being overwritten before you have a chance to recover it. Put the drive to the side and fire up your data recovery software.
Protect the Important Files on Your External Hard Disk
Here are some tips to help protect valuable data on external hard drives.
- Have more than one copy of data that is very valuable or that cannot be created. This may involve backing up your external drive to the cloud or making a full copy to another device of similar or greater capacity.
- Label external drives to minimize the potential that you will accidentally format the wrong device.
- Employ data protection tools such as Recovery Vault and Guaranteed Recovery offered by Disk Drill.
- Keep your external hard drives out of direct sunlight and do not subject them to extremes of temperature or moisture.
Getting into the habit of backing up your external hard disk is the best defense against data loss. There are multiple options available for creating backups. Here are some suggestions for reliable methods with which to back up your valuable data.
- Windows Backup: Windows users can use the Windows Backup facility built into the operating system.
- Time Machine: Mac users can take advantage of Time Machine which comes installed on macOS systems.
- Cloud Backup: Many cloud backup offerings are available that can be used with any or multiple operating systems. Some popular choices are iDrive, Carbonite Safe, and CrashPlan.
Look around for a plan that fits your budget and storage needs. You can also consider trying some 3rd-party backup solutions. However, you do it, start backing up your data today!
Other External Hard Drive Issues Worth Mentioning
Not all hard drive problems result in catastrophic data loss. However, some issues that may only be annoying at first can subsequently get worse and lead to bigger problems. Here are some signs that your external hard drive is experiencing some issues that may demand your attention. Ignoring them is not recommended!
- 🔊 Scratching or clicking sounds coming from the drive are never a good thing and are often a signal that the physical components are wearing out.
- 🐢 Slow response time when accessing the drive is another indicator that the drive is having problems.
- ⏹️ System and application crashes when using the external drive may be caused by a failing or damaged hard disk.
- 🧱 Unexplained errors when you are reading or writing to the disk can be caused by physical damage or disk corruption. We will look a little deeper into the issue of disk corruption in the next section.
If your external hard drive starts exhibiting any of these signs of looming problems, your best course of action is to contact a data recovery specialist. If you prefer DIY route, create a byte-level backup of the device that can be used for potential data recovery. This type of backup only reads your device one more time and saves the drive from the physical activity required for a recovery procedure. Disk Drill provides this capability for free and the backup can be used to recover files that had been deleted from the external drive.
