Many external factors can lead to file or data loss (such as: accidentally delete, format some hard disk or partition, virus infection, forcibly remove external storage devices, power failure, system crash, software breakdown...). But their root causes are primarily: MBR (Master Boot Record), BS (Boot Sector), DPT (Disk Partition Table) or MFT (Master File Table) is lost or damaged/corrupted. At this point, the only and ultimate solution that can restore any non-overwritten hard disk data is to use WinHex such kind of hex editor to manually correct them. But that requires you to be proficient in assembly language and the working principle of hard disk. So, what most of us need are some automation tools such like GetDataBack.

As a highly flexible and very comprehensive, complete solution for data recovering and undeleting, the R-Studio from Canada that claims to be the savior of data on a damaged hard disk, to a certain extent, has become the preferred one among similar data recovery software.
