Common Problems with EaseUS Data Recovery Wizard

April 21, 2023

EaseUS Data Recovery Wizard is data recovery software for the macOS and Windows operating systems. It features an intuitive user interface and a “free” edition that claims to restore up to 2 gigabytes (GB) of data. 

Like most popular data recovery applications, EaseUS  may be able to restore lost files in limited circumstances — but running any software could also cause permanent data loss, depending on the scenario.

At, we do not endorse data recovery software. Generally, users have one chance to restore lost data; a failed recovery attempt can be disastrous. 

To that end, we offer free media evaluations and support our services with a no data, no charge guarantee — if we’re unable to successfully recover data, you don’t pay for the attempt.  

However, we also understand that in some situations, professional data recovery services are not a practical option. In this article, we’ll provide an overview of EaseUS Data Recovery Wizard’s capabilities, along with tips for diagnosing common errors. 

If you’ve lost data due to hard drive failure, solid-state drive (SSD) failure, accidental deletion, or for any other reason, we’re here to help. Call us at 1-800-237-4200 or submit a case online to get started. 

EaseUS Data Recovery Wizard: Capabilities and Limitations

Data recovery software can fix certain logical (non-hardware) issues, but no program can fix physical issues.

If your storage media is failing, you should never run software on the drive.
EaseUS and similar programs may be capable of recovering data in the following scenarios: 

  • Accidental file deletion.
  • Data corruption caused by an unexpected shutdown or software failure.
  • Accidental or unintentional formatting or repartitioning.
  • Data loss resulting from specific types of malware infection. 

Like other applications, EaseUS cannot recover deleted data from most solid-state drives (SSDs) due to the execution of the TRIM command. Read more about the difficulties of recovering deleted data from SSDs.

No data recovery application can recover data from physically damaged media. Running software can cause an actuator head crash, and if a head crash has already occurred, the heads can permanently damage the magnetic material that stores data.

To repeat: Never run software on a physically damaged device. Even if the free version of EaseUS implies that a recovery will be possible, running the software endangers your data. 

Before Using Data Recovery Software, Understand the Risks

The major downside of data recovery software is that physical issues often share symptoms with logical issues. As we explained in the previous section of this article, running software can exacerbate a physical issue, making the problem much worse.

Additionally, users often make mistakes when installing and operating the software. For example, if you accidentally delete a file, installing software to the same device may permanently overwrite the deleted data.

Once again, we strongly discourage the use of data recovery software unless you have no other option and you’re 100% confident in the process. 

Granted, we’re a professional data recovery provider — we have an obvious incentive to discourage people from using our competitors’ services. But ultimately, our goal is to maximize the chances of recovery in every scenario. 

The safest practice is to contact an experienced provider with appropriately outfitted data recovery laboratories — but whether or not you use, we want you to get your files back. If EaseUS or any other service helps you restore your data, that’s great news for you (and a net win for the data recovery industry as a whole). 

With that in mind, we recommend following these tips when using any data recovery application (including EaseUS Data Recovery Wizard): 

  • Don’t run software if you notice any signs of a physical malfunction. For hard drives, this includes unusual noises (“clicking” or “whirring” sounds), disappearing files or folders, or a failure to boot/recognize. Read more about the symptoms of hard drive failure. 
  • Never install data recovery software on the storage device that contains the missing data. Install the software to a separate computer, then hook up the target device as a secondary/external drive.
  • Read the software’s documentation. 
  • Trust your gut. If software offers “free” recovery, but your files somehow aren’t covered in the “free” version, you may want to look elsewhere.

We strongly recommend searching for a company or software provider that offers a guarantee. If you’re unable to recover your data, you shouldn’t pay — period. 

Common Issues with EaseUS Data Recovery Wizard

Compared with professional utilities, EaseUS Data Recovery is a user-friendly tool. However, like all data recovery applications, it can run into issues when operating. The most common problem occurs when EaseUS seems frozen or stuck when performing a scan.

The software also may present the following error messages: 

  • “Scanning bad sectors, the software is trying to jump over them.”
  • “The disk information is being refreshed.”
  • “EaseUS Data Recovery Wizard has encountered a memory problem and needs to close.”
  • “Deep scan completed the problem is intelligently building trees.”

Below, we’ll address each of these issues individually. You can also view EaseUS’s description of these issues on the company’s official help page.

1. EaseUS seems frozen or stuck. 

EaseUS recommends checking whether the software is running as expected by opening Task Manager (for Windows installations) and determining whether the numbers of “CPU”, “Memory”, and “Disk (Input & Output)” change. 

“If you can recover files and the numbers changes [sic], there is nothing wrong with the software, and all you need to do is waiting patiently, [sic]” the company writes.

If the numbers aren’t changing, EaseUS recommends force-quitting the software through Task Manager. 

In this scenario, we would not recommend running the software a second time. Once again, data corruption can be caused by unexpected software shutdowns; if you’re force-quitting your data recovery software, there may be something seriously wrong with your device. If the data is important, contact a qualified data recovery provider. 

2. EaseUS error message reads: “Scanning bad sectors, the software is trying to jump over them.”

Bad sectors can occur for a variety of reasons. A large quantity of bad sectors often indicates a failing storage device — and once again, you should never run software on a failing hard drive or SSD.

Bad sectors may also occur when software shuts down unexpectedly, and data recovery software can resolve this issue in certain situations. However, “jumping” over bad sectors effectively loses the data contained within those sectors. 

If data recovery software spends a great deal of time “jumping over” bad sectors, the recovered files are likely to have some degree of corruption. That’s particularly true for photos, videos, and other multimedia files.

When EaseUS presents this issue, you can either force-stop the software or wait for the process to complete. It’s important to note that if your device is beginning to fail, scanning over every sector on the device is likely to make the problem worse.

3. EaseUS error message reads: “The disk information is being refreshed.”

This error can occur if your storage device is improperly connected to your computer. If your device is connected as a secondary drive, double-check the connections or switch to another cable.

But the message can also indicate a serious physical issue. As EaseUS notes, “If there are disk errors, indeed, you need to send the drive for manual repair before using the EaseUS software to recover the files.” 

In other words, you’ll need to treat the issue with help from a professional data recovery laboratory.

4. EaseUS error message reads: “EaseUS Data Recovery Wizard has encountered a memory problem and needs to close.”

This typically indicates that the software is mismatched with the operating system. EaseUS Data Recovery Wizard is designed for 64-bit operating systems; you can change a few settings to prevent the software from scanning file systems or RAW data.

If you’re running 64-bit windows, EaseUS notes that “all you can do is to recover data during the scanning or decrease the files to be scanned” by taking the actions above. To do that, you’ll need to open the EaseUS Data Recovery Wizard installation directory and rename two files:

  • EU[file system]SearchDLL.dll – Allows the software to scan the file system.
  • EURAWSearchDLL.dll – Allows the software to scan the file system.

Renaming these files will limit the amount of data scanned by the software, but may limit the results of the data recovery attempt. 

5. EaseUS error message reads: “Deep scan completed the problem is intelligently building trees.”

EaseUS builds “trees” to present the user with a list of potentially recoverable files. The “deep scan” is an analysis of the hard drive’s sectors, but if data is lost or corrupt, building the trees may be impossible (or extremely time-consuming). 

The company recommends checking whether the software has stalled (see Problem #1 above). If it has stalled, they recommend force-quitting the software, reconnecting the storage device, then opening Task Manager and clicking “End Task” for “EUImg.exe.” 

As you might expect, we recommend force-quitting the software and contacting data recovery professionals — failure to “intelligently build trees” may indicate an issue with the positioning of the actuator heads (for hard drives) or firmware (for hard drives, SSDs, and other devices).
