Common Causes of Data Loss
(on Different Devices)

No storage device is immune to the risk of data loss, and the consequences of data loss can always be catastrophic. However, all storage devices are affected slightly differently because of how they are used. Let’s take a closer look at the differences between them:

Because they spend most of their lives inside a computer case, internal hard drives are fairly well protected against physical damage, but that doesn’t mean that the overall risk of data loss is greatly reduced. In fact, the essential nature of internal hard drives increases the likelihood of logical data loss and other causes of data loss in computer systems that are caused by non-mechanical issues.

Commonly used as backup devices, external hard drives are frequently carried from place to place, leading to a heightened risk of data loss caused by physical damage. That’s why it’s important to use a protective case when traveling with an external hard drive, especially if the drive has spinning platters.

Most Android devices can store data on internal storage or removable memory card. Your data recovery options vary depending on which of these two locations you need to recover lost data from. Generally, it’s easier to recover data from an Android memory card since you can simply connect it to any computer with a memory card reader and use popular data recovery software.

No iPhone (or any iOS device for that matter) is equipped with a slot for a memory card, which means that all data are stored on internal storage. Because of Apple’s walled garden approach, not all computer data recovery software can scan iOS devices and recover lost data from them, and there aren’t any data recovery apps in the App Store that would make it possible to recover deleted files without a computer.

All types of SD cards (micro, mini, standard) store data on a tiny flash memory chip, which is enclosed in a plastic body. It doesn’t take much for the plastic body to break and the chip inside to suffer critical damage. Users may also experience logical data loss after improperly ejecting an SD card and preventing all read/write operations from being finished properly.

Thanks to their compact size, USB flash drives are perfect for quickly transferring files between different devices, but they can also be used as affordable backup devices. Their portable nature makes them susceptible to physical damage, while their convenience and availability cause users to take them for granted and stop paying attention to data protection best practices.

RAID arrays are an excellent way to optimize your storage performance without breaking the bank, but they’re also susceptible to data loss due to various reasons. Sudden power surges, malware attacks, hard drive failures, and improper drive replacement are just some of the things that could lead to major data compromise. However there are tools that can save the day for you.

!

Regardless of which device you use, you may encounter the following types of data loss, and you need to know which method to recover lost files you should use.

Data loss reason	Description	Solution
🥺 Human error	All people make mistakes, and some mistakes lead to data loss. The good news is that such mistakes can usually be recovered from using special data recovery software or native recovery solutions, such as File History in Windows or Time Machine in macOS.	Data recovery software
✂️ Formatting	A lot can go wrong when you click the “Format” button without double- or triple-checking which storage device you’re about to format. While the instant loss of hundreds or even thousands of files can seem utterly devastating, their recovery usually isn’t any more difficult than the recovery of a single lost file.	Data recovery software
🔨 Physical damage	Out of all common types of data loss, physical damage is the most difficult to recover from. Why? Because it requires special tools and advanced skills—something most regular users don’t have.	Data recovery service
🦠 Malware	Experts estimate that thousands of new strains of malware are released every day. While some malware is relatively innocent and more annoying than dangerous, you may also encounter sophisticated ransomware capable of completely blocking access to important files or deleting them altogether.	Data recovery software
💽 Hardware failure	Storage devices have advanced leaps and bounds during the last decade alone, but they’re still far from perfect, especially when it comes to their reliability. A single faulty resistor can cause your entire hard drive to become unreadable and impossible to recover at home.	Data recovery service
⚙️ Software corruption	Modern software applications can do all kinds of wonderful things, but they are far from perfect. In fact, the more complex software applications become, the more bugs they can hide. In extreme cases, software bugs may even corrupt important files and make them inaccessible.	Data recovery software
😈 Theft	As far as data loss threats go, computer or device theft assumes a special status because you can’t really recover data from a device you no longer have. That’s why the prevention of data loss using local or cloud backups is so important.	Local or cloud backups

Is It Possible to Recover Data for Free?

Yes, depending on the data loss situation you encounter, you might be able to recover files for free using built-in recovery tools in Windows and macOS:

All modern desktop operating systems have a special folder for deleted files that gives users a chance to change their minds and easily perform data recovery without downloading anything from the internet. In Windows, this folder is called the Recycle Bin. In macOS, it's called Trash or sometimes Trash bin.

Because files can be permanently deleted without first ending up in the Recycle Bin or Trash, both Windows and macOS come with native file backup tools that can save the day when all hope seems to be lost. The native file backup tool in Windows is called File History, while macOS users can protect their files using Time Machine.

These days, users have the option to back up important files to the cloud using solutions such as Microsoft OneDrive or Apple iCloud. The biggest advantage of cloud backups is that any computer or device with an internet connection can be used to perform file recovery, including free raw data recovery.

Data Recovery Software

More serious cases of data loss, however, can typically be solved only with the help of specialized computer data recovery software tools. Such tools are available at a variety of different price points, and some are even completely free.

A great example of a free file recovery tool is PhotoRec, a free and open-source utility software for data recovery with a text-based user interface that uses data carving techniques to recover nearly 500 different file extensions.

While cost-effective, free file recovery tools seldom recover files as reliably and effortlessly as their paid counterparts, such as Disk Drill, which offers 500 MB of lost data recovery and comes with an assortment of useful disk tools to address a variety of problems related to data loss.

Of course, whether it’s possible to recover data for free depends primarily on the underlying cause of data loss. As we’ve explained in the previous section of this page, physically damaged storage devices can seldom be recovered for free at home even with the best paid file recovery software because their repair requires professional tools and clean facilities.

!

Likewise, it’s impossible to recover permanently deleted files that have already been overwritten even though some shady websites promise free online data recovery from USB drives and other storage devices regardless of whether they’ve been overwritten or not. In fact, online data recovery websites should be avoided at all cost since it’s very dangerous to let an unknown person remotely access your device.

Factors to Consider When Selecting Data Recovery Tool

There’s no shortage of tools to recover deleted files on the internet, but which of them are worth your time and money? To answer this question, you need to pay attention to the following factors when comparing multiple available tools:

Compatibility

You need to select a tool that’s compatible not only with the storage device from which you want to recover lost files but also with your operating system. After all, even the best Mac tool won’t help you much if you’re a Windows user and don’t have access to any computer running macOS.

File format support

If you need to recover, let’s say, lost images from your computer, then you should pick a tool that supports as many image file formats as possible. Better yet, pick a tool that supports all commonly used image, video, audio, and document file formats. That way, you can address all data loss scenarios you may possibly encounter with a single tool.

Performance

Naturally, the best tools to recover deleted files should be able to actually deliver the results they promise and reliably recover all deleted files. Unfortunately, developers often promise too much but deliver too little, so reading online reviews written by real users and professional reviewers alike should always be an integral part of your selection process.

Features

Some features can make it much easier to recover deleted files. For example, it’s extremely handy to be able to preview recoverable files while they’re still technically deleted. Why? Because you can then select only the files you really want to get back and leave everything else behind.

Customer support

You wouldn’t purchase a new car without knowing that there are professional mechanics ready to address any issue you could possibly encounter while owning it, and you shouldn’t purchase a data recovery tool that doesn’t come with at least one customer support channel because no software is perfect and completely free of bugs.

Pricing

Unless you have a bottomless bank account, you should always strive to get the best value for your money possible. If you need to recover deleted files on a regular basis, then you should definitely avoid subscription-based tools since they always end up costing you more money than tools with a lifetime license option.

!

Just keep in mind that all data loss scenarios are different, so your needs and preferences may not be the same as the ones we at 7 Data Recovery are guided by. That’s why you should always do your own research and use articles such as this one as guides—not rules.

To help you get started, we at 7 Data Recovery have selected the best tools for different operating systems and ranked them according to the above-described ranking factors:

What Do You Need to Start the Data Recovery Process?

Here’s everything you need to start the data recovery process:

The storage device from which you want to recover lost files (HDD, SSD, Flash Drive, SD, etc.).

A way of connecting the storage device to your computer (memory card reader, USB cable, etc.).

Data recovery software application to perform the actual lost data recovery (Disk Drill, Photorec, etc.).

!

Sounds simple, right? That’s because starting the data recovery process is anything but complicated. What’s somewhat more complicated is successfully recovering all lost files. For that to happen, you must avoid writing any data to the storage device from which you want to recover lost files until you have restored them to a safe location.

Why? Because lost files can be recovered only when they’re still physically present on the storage device. By writing new data to the same storage device, you risk overwriting the very same files you want to undelete, which is akin to scraping old paint off a wall and painting it a new color. Even if some traces of the old paint remain, they won’t be enough to recreate the original paint job.

To put it simply: you need to stop whatever you’re doing and begin the data recovery process as soon as possible to maximize your chance of successful recovery. The same holds true if you decide to leave everything up to professionals and ship your storage device to a data recovery service.

Data Recovery Services

The fact is that not all cases of data loss can be addressed at home using various DIY file recovery solutions. Why not? Because such solutions can be used only with working storage devices. If your storage device is broken, water-damaged, or otherwise faulty, you won’t be able to scan it and recover any files from it until you repair the damage, which is where professional data recovery services (also called data retrieval services and data recovery companies) come in.

Data recovery companies such as Data Recovery Center by CleverFiles employ trained professionals who understand the ins and outs of data recovery and have access to state-of-the-art equipment, making it possible for them to address even the most gruesome physical damage.

While the services of data recovery professionals don’t come cheap (which is why they’re often used by larger organizations and not individuals), they are not nearly as expensive as many people think they are. The best data recovery companies have a “no data, no charge” policy, so you don’t have to worry about spending hundreds of hours on computer data recovery services or phone data recovery services without actually recovering any files.

How to Find Best Data Recovery Services Near Me?

To select the best local data recovery services available near your location, consider the following selection criteria:

	Free evaluation: The last thing you want is to spend hundreds of dollars just to learn that your storage device is impossible to recover, so avoid data recovery services that don’t offer a free evaluation. Better yet, choose a data recovery service that charges its customers only for recovered data.
	Success rate: The reality is that not all data recovery jobs have a happy ending. Sometimes, the lost data are simply too corrupted to be recoverable, or there is some unlucky turn of events that causes the data recovery attempt to go south. The best data recovery services have a success rate of around 98 percent, so that’s the number you should look for.
	Shipping options: Unless you’re lucky enough to live close to one of the best data recovery companies in the country, you should look for services that let you ship your storage device to them via mail.
	Technology: Naturally, you want to select a data recovery service with best-in-class equipment, clean facilities, and expertly trained professionals capable of addressing even the most complicated cases of data loss. When in doubt, don’t be afraid to call the data recovery center and ask them for more information about their tools and processes.
	Customer reviews: Online reviews can tell you a lot about the performance and attitude of a data recovery service, so read them whenever you get a chance. Just know that fake positive reviews are just as common as exaggerated negative ones, so don’t blindly trust everything you read.

How Much Does Data Recovery Cost?

Calculating the cost of data recovery can be tricky because the final sum will greatly depend on the selected approach

DIY recovery ($0–$300)

The cost of hard drive data recovery with DIY software solutions starts at $0 for free applications developed by enthusiasts, and it ends at around $300 for more expensive versions of paid software solutions.

Professional recovery ($300–$2,000+)

If you decide to hire professionals to recover your data, expect to pay at least $300 for a simple data recovery job and as much as several thousand for a more complicated one. Because data recovery services prices can vary so greatly, you should always ask for a data recovery cost estimate before you initiate a work order. Needless to say that you can save money by choosing cheap data recovery services or affordable data recovery services, but you risk recovering only a small portion of your data.

!

Other factors that influence professional data recovery costs include the amount of data to be recovered, the type of storage device, the presence of encryption, or the desired turnaround time.

Generally, data recovery services are always way more expensive than data recovery software, so it’s worth attempting DIY recovery before contacting professionals. Better still, regularly back up all important data to a safe location so that you can recover it for free should the worst happen.

Frequently Asked Questions

Updated on Mar 2, 2023 by 7 Data Recovery Team

What is the best method of data recovery?

The best way to recover lost, deleted, or corrupted data is to install a top-tier data recovery program and have it scan and retrieve the files for you. Not only are these kinds of software streamlined for the average computer user, but they’re also designed to dig deep into your storage medium to even recover data that has been lost for a very long time.

While most data recovery programs require purchase or a subscription, a lot of them offer a free version that allows you to save a limited number of files.

What is RAID data recovery?

RAID is short for “Redundant Array of Independent Disks” and is a method of storage that involves making multiple copies of data across various drives as a way of preventing data loss. RAID data recovery pertains to the retrieval and restoration of information from a RAID setup.

It often involves the use of both manual and automated processes to recover data from other RAID drives and potentially other storage media. There are a few reasons that RAID arrays may require data recovery, including failing hard drives, overwritten information, data corruption, and formatting.

What is the purpose of data recovery?

Data recovery is the process of retrieving information from a storage medium that has been deleted, compromised, lost or rendered inaccessible. Data loss can strike anytime and for various reasons, including faulty power, premature formatting, device damage, virus attacks, etc.

That being said, data recovery methods are crucial for rescuing important information, whether it’s for personal or business use. Data recovery programs are a great way of getting back files through a DIY why method, while data recovery services are the way to go for more critical scenarios that apps can’t handle.

How successful is data recovery?

The success rate of data recovery depends on several factors, such as the data loss scenario, the overall state your storage device is in, how long it’s been since the files were lost, and whether or not the lost data has already been overwritten. But data recovery programs and services have improved quite a bit over the years, and so has the likelihood of retrieving your lost files.

Where to send the hard drive for data recovery?

Quality data recovery services often offer two different ways for you to send your drives for data recovery. If there’s a good one located within your area, you can simply drop by their location and hand them your hard drive for inspection.

Otherwise, you can mail your hard drive to the service’s provided address, and they’ll diagnose its state and provide you with a cost estimation for the data retrieval process. If you agree and the service is able to recover the data, they’ll store it for you on another drive and mail it back.

How long does data recovery take?

With the best paid and free data recovery solutions, the recovery of multiple gigabytes of data can take just a few minutes—it all depends on the size of your storage device, its speed, and the kinds and number of files you want to recover.

Data recovery services are, understandably, much slower. Even if you pay extra for expedited recovery, the whole process will most likely take at least a few days since you can’t really speed up shipment times too much.

How do data recovery services work?

Data recovery services specialize in the retrieval of lost, deleted or corrupted data from a variety of storage media. They deal with a host of different data loss scenarios, including formatting, accidental deletion, physical damage, failing drives, data corruption, and more.

Data recovery services may differ in how they do things, but the gist of it is that you either drop off your drive at their store or mail it to them. Then, they diagnose it and provide you with an estimate as to the cost of recovery. Finally, they recover your files and store them in a new storage medium that they send back your way.
