In computing, data recovery is a process of retrieving deleted, 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 usual way. [1] 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).[2]

The most common data recovery scenarios involve 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 accomplished using a Live CD, or DVD by booting directly from a ROM or a USB drive 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, to 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 the 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 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 ddrescue 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;[12] 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.
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 is used to recover/restore the data files.

If the file system has been seriously damaged beyond repairing, iBoysoft data recovery software can also perform RAW drive recovery easily to recover files including documents, videos, images, etc. from a RAW USB drive, RAW SD card, and RAW external hard drive.
iBoysoft file recovery software perfectly supports recovering data accidentally deleted by selecting "Delete" and permanently deleted files by pressing "Shift+Delete" shortcuts. You can perform USB data recovery, hard drive data recovery, SD card recovery, and file recovery from other Windows-friendly storage devices.
Recycle Bin will temporarily hold deleted files for recovery until you empty it. Deleted files will be automatically removed from Recycle Bin in 30 days. With iBoysoft Data Recovery software, it is easy to recover deleted data from Recycle Bin.
When an HDD or external disk get damaged, corrupted, or inaccessible due to power failure, wrong ejection, system crash, software malfunction, or problematic file system. This professional-grade free data recovery tool can restore files from the seemingly dead disks.
The consequence of a formatted partition is that the partition becomes empty and all files are lost. This hard drive recovery software is always your reliable solution to retrieve files from a formatted drive by reconstructing the previous file system.
This free data recovery software provides an ultimately effective partition recovery to search for lost partitions that get hidden or deleted accidentally or intentionally. It can recover lost files, pictures, video files, audio files, and any other files from the entire missing partition.
Using this free data recovery software to get your important files back from any disk-based storage media including computer's internal hard disk, external hard drives, solid state drives (SSD), USB flash drives, SD cards, CF cards, memory cards, digital camera, etc.
iBoysoft Data Recovery is a tool available for Windows and Mac that you can use to scan your computer for deleted files and extract them to the disk. It's wrapped in an intuitive interface and has simple options, making it accessible to all types of users, even those without prior experience in data recovery software.
Brilliant! Took about 20 minutes to collect all my files (it was a large drive), and had them all transferred in couple of seconds and on the trial version! would recommend this data recovery software.
Of course, you can. Many of our users recovered their data accidentally deleted many years ago as long as it has not been overwritten. The data recovery tool for PC can scan your Windows computer or detected device thoroughly to dig out the old files and retrieve them.
Most file recovery software for Windows cost about US$70 to have unlimited data recovery. iBoysoft Data Recovery offers data recovery software free download and trial version to test before you spend any money.
When OS deletes a file, it removes the logical access but leaves the actual data on the disk. Data recovery software application works by reconstructing the logical access to the file before the storage space of the deleted file has been overwritten. 2ff7e9595c
