Easeus Data Recovery Wizard 5.8.0 Serial Number Free
Kathryn Garivay
I used Recuva and EASEUS Data Recovery Wizard to see if there's any difference in the files they recover. Both software were able to recover files that I want however most of the files where no longer usable. For example, for images, when you view them it's just black, for .doc files, MS Word can no longer open open them. They appear to be corrupted. This happens on both Recuva and EASEUS.
What happened was that those files were fragmented, and once they were deleted, the cluster chain was removed, so when the programs "recovered" them, what they did was to look at the starting location (which is still present) and the size of the file (which is also still present) and simply copied that many clusters in a row from the start.
This works fine if the files are stored in a single, contiguous block (i.e., defragmented), but if they were fragmented, then their blocks are spread out around the disk and the program has absolutely no way to know where/which ones to use; that's why most of the corrupted recovered files will have at least one cluster's worth of correct data, but then contain whatever happened to be in the subsequent clusters that used to belong to other files.
If the files are plain-text, then you could search the drive for unused clusters (which is a nightmare with a giant, nearly empty disk) and manually stitch the file back together (I did this a few times many years ago). But with binary files, this is effectively impossible. In fact, even with plain-text files, it is difficult at best if the file had been getting edited and saved after changes numerous times because it then becomes difficult to identify the clusters that contain blocks of the last version of the file.
The above explanation is how some data-recovery programs work. It is generally more reliable because it looks at real files that existed more recently. However (not surprisingly perhaps), it can miss out on some files. That is why other programs like PhotoRec use a different approach. Instead of looking at a deleted file's information (filename, size, timestamp, starting cluster) in directory entry and then copying the clusters from the disk, they search the whole disk for lost files.
Most file types have a signature (usually at the start of the file, in the header) which contains a sequence of bytes that identify the file as a certain type. Because of this, programs that open a file can determine if the file is teh correct type and other programs can verify the type of a file.
What some data-recovery programs do is to search the disk and check each cluster to see if they contain the signature of various different file types. If a cluster contains a signature, then it copies that cluster (and more depending on various factors) to a file.
It doesn't help after losing files, but for future reference, the best way to increase the chances of a successful recovery is to keep the disk defragmented (have the system automatically defragment when it idles).
So, yes, fragmentation can be an issue when recovering data but is not by definition. For example, it depends highly on the file system you are recovering data from. It also depends on how the data was lost.
For example, assume a formatted volume and we'll compare FAT based FS vs. NTFS: Yes, in the FAT based FS (FAT32, exFAT) fragmented files are an issue because the file allocation tables were wiped during the format. On NTFS most MFT entries will survive and as long we have those fragmented file recovery is no issue at all as we have the complete runlists for the files.
Example 2: a RAW volume. This can be caused by major file system corruption but also by something as simple as a corrupted boot sector BIOS parameter block. If the latter on both FAT32, exFAT and NTFS volume you should be able to achieve a close to 100% perfect recovery, fragmented files or not. However the reason that popular tools like Recuva and Easeus often fail in these situations are that they're not that good in working out a valid virtual file system.
Then one remark about software that scans for file signatures, or 'carvers'. It is true that for many files it is not possible to detect a file end so you potentially end up with huge files. However there's plenty of files that you can detect file ends for + there a number of rules of thumb you could apply here too.
There are tools specifically designed to puzzle together fragmented files even with absence of any valid file system structures. However, they often work only for very specific file types, such as JPEG, or MP4 or XLS. The reason for this being they need specialized 'knowledge' about the actual file structure to reconstruct valid files.
Instruction
In order to increase the success rate of recovery, the program would list every possible detected file on your disk after a full scan. So you may see a huge number of files even larger than the disk capacity. It seems clueless to locate your desired files among them. No worry. We prepared the following tips for you to directly locate your files.
Overview of the Scan Result
After the scan completes, you will be presented with a detailed scan result, where you can take some time to filter the files you want to recover.
Files found through advanced scan. Those files are listed by device model and user info. For example. The camera folder will show you a list of photos that are shoot by different camera brands. The Artist folder will show you a list of the songs by different singers. And the PDF, PTT, Excel, Word folders will show you a list of different users created those documents.
2. Although the file lose its original name, but the file size would still be the same. Thus, we can try to locate the files in another way: Input the file extension in the search box and it will give you a result that associated with that file type. List the those found files by size and be focus on the missing file with the same size as the one you were not able to be opened from the previous folder.
Note:
1. Please NEVER try to recover data to the original location where contains lost data until you have all your data recovered.
2. Only Recover button in the lower right corner can help you save files to a specified location. Save Session exports scan result only for later use.
We also offer remote assistance service to help user filter a large amount of scan result more efficiently. If you need that, please contact us via Livechat or sup...@easeus.com, we will arrange a remote session as soon as we can.
Over the course of time, most Windows users will experience a data loss event. This can happen for a number of reasons, many of which are out of your control. You might find that some files are missing after an application or operating system upgrade. Perhaps you are sorting through your photos and inadvertently delete a bunch of pictures.
In the case of unexplained missing files or if you have emptied your Recycle Bin before discovering that you have lost some data, you need to use specialized data recovery software. Data recovery applications will scan your hard drive and attempt to restore files that have not yet been overwritten by the operating system.
EaseUS Data Recovery offers the user a simple way to recover from a variety of data loss scenarios. It is supported on all the newest versions of Windows & macOS and can be used to recover just about any type of deleted file. Retrieve lost files from an emptied Recycle Bin by employing the deep scanning capabilities of this application.
This powerful data recovery tool can help you restore data from formatted drives or lost partitions as well as from damaged storage media. The software provides a 3-step wizard to simplify the recovery process.
The first alternative we will look at is Disk Drill data recovery software by CleverFiles. This comprehensive and feature-rich recovery tool has a number of additional features designed to help you maintain the health of your hard drive and the security of your data.
Another free option for Windows users facing a data loss situation is Recuva. It can recover files from damaged disks and formatted drives as well as accidentally deleted files that are no longer in the Recycle Bin.

An overall competent file recovery tool, EaseUS Data Recovery Wizard Pro is easy to use but slow. It's also expensive for single users to consider and is more suited to small business users rather than large corporations or organizations and public bodies.
Its set of features certainly suggests that it'll get the job done. It can hunt through conventional hard disks and even damaged operating systems for photos, and it supports more file and device types than virtually every rival. It's even got a generous free version alongside powerful paid options.
A free version of Data Recovery Wizard is available, but this is not suitable unless you only need basic functionality. While the free product does restore files from hard drives, SSDs and external HDDs, you don't get NAS support, remote assistance or any of its photo and video repair functionality.
Previously EaseUS' free trial was just for 30-days and offered scanning but no actual recovery capabilities, which seemed pretty cruel. It appears the developers have listened to user feedback since then, as the free version now allows you to recover up to 2GB of data.
We had a hard time squaring this free allowance on our tests, as after attempting to recover a 100MB folder on a 512MB drive just three times, our allowance was reduced to around 200MB. It's possible the 2GB limit may apply to the size of the drive being scanned instead of the amount of data recovered.
