Okay so what happened? Well, data loss is an error condition in information systems in which information is destroyed by failures or neglect in storage, transmission, or processing. Information systems implement backup and disaster recovery equipment and processes to prevent data loss or restore lost data which sometimes don't work.
Data loss could be caused by:
- Intentional Action
Intentional deletion of a file or program
- Unintentional Action
Accidental deletion of a file or program
Misplacement of CDs or Memory sticks
Inability to read unknown file format
° Power failure, resulting in data in volatile memory not being saved to permanent memory.
° Hardware failure, such as a head crash in a hard disk.
° A software crash or freeze, resulting in data not being saved.
° Software bugs or poor usability, such as not confirming a file delete command.
° Business failure (vendor bankruptcy), where data is stored with a software vendor
° Data corruption, such as file system corruption or database corruption.
° Natural disaster, earthquake, flood, tornado, etc.
° Theft, hacking, sabotage, etc.
° A malicious act, such as a worm, virus, hacker or theft of physical media.
According to research hardware failure and human error are the two most common causes of data loss, accounting for roughly three quarters of all incidents. Another cause of data loss is a natural disaster.
That's where a data recovery service comes in; Data recovery service is the process of salvaging and handling the data through the data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. You can recover lost data from storage media such as internal or external hard disk drives, solid-state drives (SSD), USB flash drive, storage tapes, CDs, DVDs, RAID, and other electronics. A data recovery service may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system (OS).There are labs and engineers that have seen all issues and have engineered solutions to fit with our client's requirements to recover lost data, including but not limited to; dropped or smashed hard disks, snapped or broken USB devices, firmware corruption, and logical issues with file systems resulting in non booting computer systems, virus damages and malware.
There are four phases to recover lost data. Each phase stands for different level and range of data recovery capabilities, each phase requires different repair tools and data recovery tools to work with and each phase must be treated properly to make sure the maximum data are finally to be recovered. Even when phase 1 is not required, it is always recommended to perform phase 2.
Phase 1: Repair the hard drive
Phase 2: Image the drive to a new drive or a disk image file.
Phase 3: Logical recovery of files, partition, MBR, and MFT.
Phase 4: Repair the damaged files that were retrieved.
