At some point most people learn the hard way the importance of backups. Chances are you already have something set up, perhaps using a cloud-based program such as Google Drive, Dropbox, or Microsoft's OneDrive. You might have everything routinely saved to a USB stick or to an external hard drive as well. You might even have all three in play.
However, while syncing files and folders across multiple devices makes it easy to save them, it unfortunately also makes it easy to delete them by accident. Trying to organize and rearrange folders is a great way to accidentally misplace an important file, only to realize what happened too late.
This is where file recovery software can come into their own, and while there are some expensive paid plans, we're going to list the best of the free file recovery software here. However, the caveat is that these are never going to be as powerful as the more expensive versions and are intended for situations which only require an easy recovery.
Even still, they still have their place and it's definitely a good idea to have something like any of these in place, just in case - so that the moment you realize you've make a mistake and misplaced something, you can recover it quickly and easily enough, preventing you from need the big paid-for guns in the first place.

1. MiniTool Power Data Recovery Free
Limit by file type
Fast
MiniTool Power Data Recovery Free is the only program in this round up which provides you with essential advice during the installation: do not install the software to the drive you want to recover data from, as you may overwrite files.
This version is free, but there are paid-for editions available as well, so you will realise that there are a few restrictions.
You can only recover 1GB of data, you don’t have the option of saving scan results to work with later, and a few other options are missing – but there's absolutely nothing that stops this from being a great free recovery utility, aside from the occasional ad here and there.
You can limit scans to specific files types, and MiniTool Power Data Recovery Free is capable of getting files back from partitions you are not even able to see, and there's support for removable drives including optical media.
Scans are pleasingly fast, and results are searchable to make it easier to find exactly what you're looking for. A superb piece of software that worth of your attention.

2. Disk Drill
Simple to use
Featuring a delightful simple interface, Disk Drill make file recovery very simple. There's no need to fiddle with complex options, and the program can be used to scan local as well as removable drives and memory cards. Performance a scan of your chosen drive and you're presented with a list of recoverable files, grouped by type, and you have the option of previewing image files in advance. It's a simple, effective tool with a high success rate.
What seems like a nice touch for anyone who is a little nervous about data recovery, is the inclusion of a quick tutorial the first time the program is run – but it is simplistic in the extreme and of little real value, and ultimately serves as an ad to upgrade to the Pro version.
Disk Drill is available for both macOS and Windows. Upgrading to Pro increases the number of computers the software can be used on, and opens up more options such as advanced scanning and wider file system support. For most people, however, the free version should cover all the usual eventualities.
3. EaseUS Data Recovery Wizard Free
Preview option
Keeping things nice and simple, EaseUS Data Recovery Wizard Free is the friendly, accessible face of recovering lost files. Fire up the program and you're presented with a screen asking which drive you would like to scan for recoverable data – you then just need to hit the Scan button. There are no options to configure, but if you know exactly where a file has gone missing from, you can specify a folder to scan to speed things up.
Results are presented in an Explorer-style view which is easy to navigate, but unfortunately there is no indication of the quality of files that have been found – although a preview option is available. You can then select the files you're interested in, and restore them.
It's worth noting that the free version of the program only lets you recover up to 2GB of data (500MB by default, but this can be increased from within the program) before you have to upgrade to the paid-for version. While this is not enough for a complete hard drive recovery, it should be enough to help you to get back your most important files when you need to.
4. Recuva
Easy wizard
Secure deletion option
Something of a stalwart of the data recovery genre, Recuva has managed to build up a dedicated following – and it's not hard to see why. The program can recover data not only from hard drives and memory cards, but also your iPod.
While some data recovery tools make this easy by having a simple interface, Recuva takes things further and guides you through the entire process with a wizard. You can perform a lengthy deep scan to track down all recoverable data, or you can limit the search if you're looking for something specific – and it's nice to have this flexibility.
As an added bonus, there is a secure deletion option which does the exact reverse of the main feature of the program – it deletes files you are sure you no longer need and renders them unrecoverable.
A downside to the program is the heavy promotion of the Pro version of the app, but if you can turn a blind eye to this, you have a powerful tool on your hands – and you can probably live without support for virtual hard drives anyway!
5. UnDeleteMyFiles Pro
Multiple tools
Disk snapshot
Despite the inclusion of the word 'pro' in the name, this program is still free; there is, in fact, no non-pro version.
The look of UnDeleteMyFiles Pro may not be particularly appealing, but don’t let that put you off too much as there are multiple tools included here, not just data recovery. Recovery can be a little hit and miss as there is no indication of the quality (or recoverability) of files – you just have to hope that the file that are found are in a reasonable state.
When it comes to data recovery, there aren't really all that many options other than the ability to search for particular types of files to reduce the size of the list you have to sort through.
In terms of extras you also get a disk snapshot tool which basically backs up your drive so you can recover data at your leisure, a secure file deletion tool, and email recovery. Worth checking out, even if this is not necessarily the best of the bunch.
Also consider these free recovery options
There are also other free file recovery software options worth considering, though consolidation in the market means some old timers have been bought up by bigger companies and repackaged, while some haven't been updated for a while but should still work well at what they need to do. Here then are some additional releases to consider for file and folder recovery:
Stellar Free Data Recovery is another Techradar favorite, providing an all-in-one recovery solution for retrieving deleted files - and of course, all for free. Stellar's software can recover documents, photos, video, audio, and email data files, even if they have been deleted from your PC's recycle bin. It can also help recover files lost by a corrupted harddrive, missing or lost partitions, as well as after a virus attack.
Active@ File Recovery is another strong platform worth considering, not least because it can work with such a wide range of different file partitions, making it useful for a range of different Windows set ups and installations. As well as being able to cover all common file types, it also supports recovery across a large number of media, such as harddrive, external disks, USB drives, memory cards, and devices such as digital cameras.
Puran File Recovery is another old favorite, and while it hasn't been updated in a couple of years, it does provide support for Windows 10. The interface itself is quite simple, but it uses a powerful recovery engine to retrieve lost or deleted files. You can chose to opt for a quick, deep, or full scan in order to recovery your files. Once found, they can be saved with their file paths still intact, which means they should return from the original folder or location they disappeared from.
Undelete 360 is another program established freeware program that hasn't been updated in a few years, but still offers the potential to recovery files not just from your harddrive but from a range of external media. This can include USB drives, digital cameras, and even floppy drives - if you're still using one. Undelete 360 can recover files and folders from a wide range of situations, and again while the interface is simple, it's a powerful little piece of software.
Glary Undelete supports a wide range of file forms and storage systems, as well as recovery for external devices. When recovering a file, results can be filtered, making it easier to find and locate the missing or deleted file you're looking for. While the free version of the software hasn't been updated in a couple of years, the paid-for version is still going strong.
- Avoid losing files at all with the best free backup software
In computing, data recovery is a process of salvaging (retrieving) inaccessible, lost, corrupted, damaged or formatted data from secondary storage, removable media or files, when the data stored in them cannot be accessed in a normal way. The data is most often salvaged from storage media such as internal or external hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, magnetic tapes, CDs, DVDs, RAID subsystems, and other electronic devices. Recovery may be required due to physical damage to the storage devices or logical damage to the file system that prevents it from being mounted by the host operating system (OS).
The most common data recovery scenario involves an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive. This can be easily accomplished using a Live CD or DVD by booting directly from a ROM instead of the corrupted drive in question. Many Live CDs or DVDs provide a means to mount the system drive and backup drives or removable media, and to move the files from the system drive to the backup media with a file manager or optical disc authoring software. Such cases can often be mitigated by disk partitioning and consistently storing valuable data files (or copies of them) on a different partition from the replaceable OS system files.
Another scenario involves a drive-level failure, such as a compromised file system or drive partition, or a hard disk drive failure. In any of these cases, the data is not easily read from the media devices. Depending on the situation, solutions involve repairing the logical file system, partition table or master boot record, or updating the firmware or drive recovery techniques ranging from software-based recovery of corrupted data, hardware- and software-based recovery of damaged service areas (also known as the hard disk drive's 'firmware'), to hardware replacement on a physically damaged drive which allows for extraction of data to a new drive. If a drive recovery is necessary, the drive itself has typically failed permanently, and the focus is rather on a one-time recovery, salvaging whatever data can be read.
In a third scenario, files have been accidentally 'deleted' from a storage medium by the users. Typically, the contents of deleted files are not removed immediately from the physical drive; instead, references to them in the directory structure are removed, and thereafter space the deleted data occupy is made available for later data overwriting. In the mind of end users, deleted files cannot be discoverable through a standard file manager, but the deleted data still technically exists on the physical drive. In the meantime, the original file contents remain, often in a number of disconnected fragments, and may be recoverable if not overwritten by other data files.
The term 'data recovery' is also used in the context of forensic applications or espionage, where data which have been encrypted or hidden, rather than damaged, are recovered. Sometimes data present in the computer gets encrypted or hidden due to reasons like virus attack which can only be recovered by some computer forensic experts.

Physical damage[edit]
Game gear emulator apk. A wide variety of failures can cause physical damage to storage media, which may result from human errors and natural disasters. CD-ROMs can have their metallic substrate or dye layer scratched off; hard disks can suffer from a multitude of mechanical failures, such as head crashes, PCB failure and failed motors; tapes can simply break.
Physical damage to a hard drive, even in cases where a head crash has occurred, does not necessarily mean there will be permanent loss of data. The techniques employed by many professional data recovery companies can typically salvage most, if not all, of the data that had been lost when the failure occurred.
Of course there are exceptions to this, such as cases where severe damage to the hard drive platters may have occurred. However, if the hard drive can be repaired and a full image or clone created, then the logical file structure can be rebuilt in most instances.
Most physical damage cannot be repaired by end users. For example, opening a hard disk drive in a normal environment can allow airborne dust to settle on the platter and become caught between the platter and the read/write head. During normal operation, read/write heads float 3 to 6 nanometers above the platter surface, and the average dust particles found in a normal environment are typically around 30,000 nanometers in diameter.[1] When these dust particles get caught between the read/write heads and the platter, they can cause new head crashes that further damage the platter and thus compromise the recovery process. Furthermore, end users generally do not have the hardware or technical expertise required to make these repairs. Consequently, data recovery companies are often employed to salvage important data with the more reputable ones using class 100 dust- and static-free cleanrooms.[2]

Recovery techniques[edit]
Recovering data from physically damaged hardware can involve multiple techniques.[3] Some damage can be repaired by replacing parts in the hard disk. This alone may make the disk usable, but there may still be logical damage. A specialized disk-imaging procedure is used to recover every readable bit from the surface. Once this image is acquired and saved on a reliable medium, the image can be safely analyzed for logical damage and will possibly allow much of the original file system to be reconstructed.

Hardware repair[edit]
Media that has suffered a catastrophic electronic failure requires data recovery in order to salvage its contents.
A common misconception is that a damaged printed circuit board (PCB) may be simply replaced during recovery procedures by an identical PCB from a healthy drive. While this may work in rare circumstances on hard disk drives manufactured before 2003, it will not work on newer drives. Electronics boards of modern drives usually contain drive-specific adaptation data (generally a map of bad sectors and tuning parameters) and other information required to properly access data on the drive. Replacement boards often need this information to effectively recover all of the data. The replacement board may need to be reprogrammed. Some manufacturers (Seagate, for example) store this information on a serial EEPROM chip, which can be removed and transferred to the replacement board.[4][5]
Each hard disk drive has what is called a system area or service area; this portion of the drive, which is not directly accessible to the end user, usually contains drive's firmware and adaptive data that helps the drive operate within normal parameters.[6] One function of the system area is to log defective sectors within the drive; essentially telling the drive where it can and cannot write data.
The sector lists are also stored on various chips attached to the PCB, and they are unique to each hard disk drive. If the data on the PCB do not match what is stored on the platter, then the drive will not calibrate properly.[7] In most cases the drive heads will click because they are unable to find the data matching what is stored on the PCB.
Logical damage[edit]
Result of a failed data recovery from a hard disk drive.
The term 'logical damage' refers to situations in which the error is not a problem in the hardware and requires software-level solutions.
Corrupt partitions and file systems, media errors[edit]
In some cases, data on a hard disk drive can be unreadable due to damage to the partition table or file system, or to (intermittent) media errors. In the majority of these cases, at least a portion of the original data can be recovered by repairing the damaged partition table or file system using specialized data recovery software such as Testdisk; software like dd rescue can image media despite intermittent errors, and image raw data when there is partition table or file system damage. This type of data recovery can be performed by people without expertise in drive hardware as it requires no special physical equipment or access to platters.
Sometimes data can be recovered using relatively simple methods and tools;[8] more serious cases can require expert intervention, particularly if parts of files are irrecoverable. Data carving is the recovery of parts of damaged files using knowledge of their structure.
Overwritten data[edit]
After data has been physically overwritten on a hard disk drive, it is generally assumed that the previous data are no longer possible to recover. In 1996, Peter Gutmann, a computer scientist, presented a paper that suggested overwritten data could be recovered through the use of magnetic force microscopy.[9] In 2001, he presented another paper on a similar topic.[10] To guard against this type of data recovery, Gutmann and Colin Plumb designed a method of irreversibly scrubbing data, known as the Gutmann method and used by several disk-scrubbing software packages.
Substantial criticism has followed, primarily dealing with the lack of any concrete examples of significant amounts of overwritten data being recovered.[11] Although Gutmann's theory may be correct, there is no practical evidence that overwritten data can be recovered, while research has shown to support that overwritten data cannot be recovered.[specify][12][13][14]
Solid-state drives (SSD) overwrite data differently from hard disk drives (HDD) which makes at least some of their data easier to recover. Most SSDs use flash memory to store data in pages and blocks, referenced by logical block addresses (LBA) which are managed by the flash translation layer (FTL). When the FTL modifies a sector it writes the new data to another location and updates the map so the new data appear at the target LBA. This leaves the pre-modification data in place, with possibly many generations, and recoverable by data recovery software.
Lost, deleted, and formatted data[edit]
Sometimes, data present in the physical drives (Internal/External Hard disk, Pen Drive, etc.) gets lost, deleted and formatted due to circumstances like virus attack, accidental deletion or accidental use of SHIFT+DELETE. In these cases, data recovery software are used to recover/restore the data files.
Logical bad sector[edit]
In the list of logical failures of hard disks, logical bad sector is the most common in which data files cannot be retrieved from a particular sector of the media drives. To resolve this, software is used to correct the logical sectors of the media drive. If this is not enough, the hardware containing the logical bad sectors must be replaced.
Remote data recovery[edit]
Recovery experts do not always need to have physical access to the damaged hardware. When the lost data can be recovered by software techniques, they can often perform the recovery using remote access software over the Internet, LAN or other connection to the physical location of the damaged media. The process is essentially no different from what the end user could perform by themselves.[15]
Remote recovery requires a stable connection with an adequate bandwidth. However, it is not applicable where access to the hardware is required, as in cases of physical damage.
Four phases of data recovery[edit]
Usually, there are four phases when it comes to successful data recovery, though that can vary depending on the type of data corruption and recovery required.[16] Virtual dj 7.0 5 full download.
- Phase 1
- Repair the hard disk drive
- The hard drive is repaired in order to get it running in some form, or at least in a state suitable for reading the data from it. For example, if heads are bad they need to be changed; if the PCB is faulty then it needs to be fixed or replaced; if the spindle motor is bad the platters and heads should be moved to a new drive.
- Phase 2
- Image the drive to a new drive or a disk image file
- When a hard disk drive fails, the importance of getting the data off the drive is the top priority. The longer a faulty drive is used, the more likely further data loss is to occur. Creating an image of the drive will ensure that there is a secondary copy of the data on another device, on which it is safe to perform testing and recovery procedures without harming the source.
- Phase 3
- Logical recovery of files, partition, MBR and filesystem structures
- After the drive has been cloned to a new drive, it is suitable to attempt the retrieval of lost data. If the drive has failed logically, there are a number of reasons for that. Using the clone it may be possible to repair the partition table or master boot record (MBR) in order to read the file system's data structure and retrieve stored data.
- Phase 4
- Repair damaged files that were retrieved
- Data damage can be caused when, for example, a file is written to a sector on the drive that has been damaged. This is the most common cause in a failing drive, meaning that data needs to be reconstructed to become readable. Corrupted documents can be recovered by several software methods or by manually reconstructing the document using a hex editor.
Restore disk[edit]
The Windows operating system can be reinstalled on a computer that is already licensed for it. The reinstallation can be done by downloading the operating system or by using a 'restore disk' provided by the computer manufacturer. Eric Lundgren was fined and sentenced to U.S. federal prison in April 2018 for producing 28,000 restore disks and intending to distribute them for about 25 cents each as a convenience to computer repair shops.[17]
