recoveries

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. 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).Logical failures occur when the hard drive devices are functional but the user or automated-OS cannot retrieve or access date stored in it. It can occur due to corrupt engineering chip, lost partitions, deleted data, firmware failure, failed formatting/re-installation.Data recovery can be a very simple or technical challenge. This is why there are specific software companies specialized in this field.
