External USB drives are getting bigger, faster and more affordable every day. They are therefore Data Recovery almost ideal for use as a mass storage device for music, videos, photos or as backup storage for files and systems.
While USB drives are generally very reliable for storing files, they pose particular risks compared to internal drives and non-removable Data Recovery media. The most obvious risks are physical risks, such as a disc being dropped, mishandled, or exposed to harsh environments (extreme heat or cold, humidity, or direct sunlight) for an extended period of time.
Logical errors caused by improper removal of a computer or sudden power failure are also a common risk for removable hard drives and flash drives. All major operating systems include an “eject” command, which prepares your drive to be physically removed from the computer or device. This ensures that no write operation is in progress when the disk is removed.
If a disk is grossly disconnected while the operating system is accessing it, the disk’s file system may be damaged, rendering the disk (and the files on it) inaccessible. When trying to mount the disk, the computer will not be able to recognize the file system or may consider it as unallocated space (and therefore ask to format the disk). The screenshot below shows a damaged disk in Windows Disk Management.
Judging from the information provided by these disk utilities, it may appear that the data on the disk has been completely erased or lost. However, in most cases this is not the case. Some or all of your data may still be on the disk, although it is invisible to the operating system.
R-Studio is a data recovery utility that allows you to “see” that data in a way that the operating system cannot. R-Studio can identify and analyze damaged disk contents without relying on an intact file system. This allows you to recover your important Twitter data even if the disc is damaged beyond readability. This article will show you how to do it, step by step.
This step-by-step data recovery tutorial assumes that your disk is in good physical condition and is damaged due to a logical error (eg improper disconnection or accidental reformatting). If there seems to be a hardware problem with the drive or if the drive has suffered some sort of physical trauma, it is best to seek the services of a professional data recovery specialist. In addition to checking that the cables are securely connected, any “do it yourself” data recovery attempt can actually worsen your chances of recovering data if your drive has a serious physical malfunction. Signs that a drive is physically failing include
