DIY Data Recovery vs Professional Data Recovery Services
DIY Data Recovery
➕ There’s no shortage of DIY data recovery software applications that make it possible even for regular home users to recover lost data.
➕ In most situations, the recovery process should take less than hour from start to finish.
➖ Even the best data recovery software can’t recover data from physically damaged storage devices.
➕ Many reputable data recovery services don’t charge money unless they actually deliver at least some results.
➖ Professional data recovery services can be very expensive, with prices often reaching thousands of dollars.
➖ It will likely take at least several days for your recovered data to arrive from your data recovery center of choice.
So, Which Data Recovery Approach I Should Choose?
Use Data Recovery Software When Possible
Let Professionals Deal With Physical Damage
Data recovery software is the right choice in most situations, but not when it comes to physical damage. If the storage device you want to recover can’t even be connected to your computer or recognized properly, then you shouldn’t waste the one chance you might have at its recovery and send it to professionals straight away.

What Is Data Recovery?
Data recovery is the process of restoring access to data that is no longer accessible because it has been deleted, formatted, or otherwise lost.
Access to inaccessible data can be restored because files often remain physically present on the storage device long after they’ve been permanently deleted, making them impossible to open through a standard file manager.
During data recovery, inaccessible data is salvaged from the storage device and moved to a safe location. This process can be performed for as long as the data has not been overwritten or physically purged from the storage device (which does automatically happen with some modern SSDs).
Recommended Data Recovery Steps
Look in the Recycle Bin or Trash
Modern operating systems typically don’t resort to permanent deletion right away. Instead, they move deleted files to a temporary storage area (Recycle Bin on Windows and Trash on macOS), where they stay for some time, making it easy for you to retrieve them. To avoid wasting time and money, you should always start by checking the Recycle Bin or Trash before moving on to more complicated recovery methods.
Use your system backup tool
If you’ve activated your operating system’s built-in backup tool (File History on Windows and Time Machine on macOS), then you’re in luck because you can use it to retrieve your lost files without downloading third-party data recovery software or contacting data recovery professionals.
Download data recovery software
Regardless of which operating system you use, there are many data recovery software applications that you can download to recover lost data, including documents, audio and video files, emails, and more. Some data recovery software applications are geared toward professionals, but the most popular solutions tend to be aimed at regular home users with no previous data recovery experience.
Contact data recovery professionals
No luck using data recovery software to retrieve lost files? In that case, it’s time to contact data recovery professionals and ship your storage device to them. The best data recovery centers don’t charge their customers any money unless they successfully recover at least some lost data, and they offer a free evaluation so that you know what to expect before you commit.
Chances of Successful Data Recovery
As long as you begin the recovery process in a timely manner, your chances of recovering an accidentally deleted file are very high. To increase them even further, use the best data recovery solution available and avoid using the device on which the file if possible. To be extra safe, you can put the device in read-only mode (SD cards make this easy with their lock switch).
Recovery after file system formatting
Even though formatting may seem like the ultimate destructive operation, it’s actually not that difficult to recover the original content of the formatted storage device. The only exception is the so-called secure format option (called Full Format in Windows and Secure Erase in macOS), which overwrites the original data to make their recovery impossible.
The term logical damage encompasses all non-mechanical damage, including data corruption, system crashes, driver problems, and data loss caused by software bugs. Depending on how extensive logical damage is, you should be able to recover at least some lost data—if not all.
Loss of information about a partition
When you lose partition information, your operating system may become inaccessible, and your hard drive may appear to be completely empty. But when it comes to data recovery, the loss of partition information is actually no big deal because your data is still there on the storage device in its original form.
Various strains of malware can cause different forms of data loss. Some simply hide files from view, while others encrypt them using an unbreakable encryption algorithm. If you get lucky and experience a less serious malware infection, then you should be able to avoid data loss entirely. However, if your device becomes infected with state-of-the-art ransomware, you may not be able to recover any data at all.
Storage devices fail for all kinds of reasons. A broken connector on a USB flash drive, for example, can be repaired by a skilled professional without much effort, while a shattered hard drive would be too big of a challenge even for an expert equipped with advanced tools.
Frequently Recovered Devices
PC (laptops & desktops)
Thanks to a wide selection of data recovery software for Windows and Linux, recovering lost data from laptops and desktop computers is an easily solvable challenge even for less experienced users.
Mac (MacBook, iMac, etc.)
Mac users are not immune to data loss. Fortunately, most leading data recovery software applications support macOS. Just know that the applications found in the App Store are often severely limited in terms of functionality due to the restrictions imposed by Apple on their developers. You can avoid these limitations by downloading macOS data recovery software directly from its developers.
Hard disk drive (HDD)
Traditional spinning hard drives have come a long way in terms of not just storage capacity but also reliability. Still, they’re far from perfect, which explains why so many of their users are interested in suitable data recovery solutions.
Solid-state drive (SSD)
Unlike spinning hard drives, SSDs have a finite lifespan, so data loss is something all users who don’t take certain precautions will experience. The problem is that data recovery from SSDs isn’t always possible due to performance-enhancing technologies such as TRIM.
Memory cards (SD, microSD, MMC, etc.)
Thanks to their compact size and increasingly impressive storage capacity, memory cards can be found in all kinds of devices, from digital cameras to smartphones. Unless physically damaged, they can be recovered using readily available data recovery software.
USB flash drives
It would be difficult to find a more convenient category of storage devices than USB flash drives. Because of their portability, USB flash drives are formatted much more frequently than regular hard drives, which increase the likelihood of data loss, but they can be recovered using the same techniques.
Android (smartphones & tablets)
The Android operating system gives users a lot of freedom to enjoy their devices to their full potential, and this freedom sometimes results in the loss of important data. Fortunately, its recovery is possible using both native Android apps and PC/Mac software.
iOS (iPhone, iPad, iPod)
Recovering data deleted on an iOS device can be tricky because of various restrictions imposed by Apple and the way iOS in general handles file deletion. Still, you might get lucky if you use the right data recovery software, and you can always attempt to recover data from a local or cloud backup.
Data recovery specificities of different OS
Found on many portable storage devices, from memory cards to USB flash drives, the FAT file system family has been around for a long time, which is one reason why its recovery rarely ever presents a problem.
This most advanced member of the FAT file system family may not be as widely supported as its older siblings, but at least it can be recovered just as easily using any software that supports it.
As the default file system of Windows computers, NTFS is commonly found on hard disk drives and solid-state drives. Despite its fragmentation issues, NTFS recovery is something most data recovery solutions handle without breaking a sweat.
Created as a resilient file system for servers, ReFS features built-in handling of hard disk drive failure and redundancy, among other things, making data recovery easier and more likely to end successfully.
Before the arrival of macOS High Sierra, HFS+ was the default file system on Apple computers. Deleted files can be recovered from storage devices that use HFS+ until they become overwritten with new data.
The adoption of solid-state drives prompted Apple to switch to a new file system, one that would take better advantage of their performance. To do that, APFS enables TRIM to immediately wipe deleted data, making its recovery extremely difficult.
Dating back to 1992, the ext2 file system is simple and efficient, making it great for embedded devices and various low-power computers. When recovering data from it, file names get lost because journaling isn’t supported.
Like their names suggest, ext3 and ext4 are more advanced versions of the ext2 file system, offering support for journaling. As such, it’s often possible to recover files with their original names from ext3 and ext4 storage devices.
This modern file system supports many advanced features, such as pooling, snapshots, and checksums, which make it more resilient and lead to improved data recovery chances.
Because ReiserFS actively reduces internal data fragmentation and stores all metadata in a single, combined B+ tree, complete recovery of lost files is not just possible but likely.
This family of journaling file systems was created by IBM in 1990, and it’s still used today by some Linux users. During data recovery, file names often become lost, but that’s the only major issue JFS/JFS2 presents.
You can expect good results when recovering data from XFS-formatted storage devices because this file system employs metadata journaling and delayed allocation, among other features.
