Overwritten data recovery software

Overwritten data recovery software, recover overwritten data in Windows 7/10/XP/8/Vista usb hard drive disk laptop or desktop computer photos videos word excel ppt files. It supports EXFAT/FAT32/NTFS file systems.

Aidfile provide 2 ways to recover overwritten files,"Undelete"and "Full scan"; as we all know,overwriiten files can not be recovered 100%.We can say many files such as jpeg photos can be recovered.But no one can make all the lost files be recovered .So we suggest you download and instal the run this tool and make a scanning.

Also after some files overwritten after format or deleted hard drive partition file system, you can try "Unformat" and "Recover partition" .

 

After data has been physically overwritten on a hard disk drive, it is generally assumed that the previous data are no longer possible to recover. overwritten data could be recovered through the use of magnetic force microscope. a method of irreversibly scrubbing data, known as the Gutmann method and used by several disk-scrubbing software packages. Substantial criticism has followed, primarily dealing with the lack of any concrete examples of significant amounts of overwritten data being recovered. Although Gutmann's theory may be correct, there is no practical evidence that overwritten data can be recovered, while research has shown to support that overwritten data cannot be recovered. Solid-state drives (SSD) overwrite data differently from hard disk drives (HDD) which makes at least some of their data easier to recover. Most SSDs use flash memory to store data in pages and blocks, referenced by logical block addresses (LBA) which are managed by the flash translation layer (FTL). When the FTL modifies a sector it writes the new data to another location and updates the map so the new data appear at the target LBA. This leaves the pre-modification data in place, with possibly many generations, and recoverable by data recovery software.

 

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, 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 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. Files have been accidentally "deleted" from a storage medium by the users. Typically, the contents of deleted files are not removed immediately from the physical drive; instead, references to them in the directory structure are removed, and thereafter space the deleted data occupy is made available for later data overwriting. In the mind of end users, deleted files cannot be discoverable through a standard file manager, but the deleted data still technically exists on the physical drive. In the meantime, the original file contents remain, often in a number of disconnected fragments, and may be recoverable if not overwritten by other data files.data recovery is also used in the context of forensic applications or espionage, where data which have been encrypted or hidden, rather than damaged, are recovered. Sometimes data present in the computer gets encrypted or hidden due to reasons like virus attack which can only be recovered by some computer forensic experts.
