Undelete files from external hard drive, external hard drive data recovery software in Windows 7/10/XP/8 due to accidentally deleted files by a mistake, shift delete files, permanently deleted files after empty recycle bin.
External hard disk drives are usually available as pre-assembled integrated products, but may be also assembled by combining an external enclosure (with USB or other interface) with a separately purchased drive. They are available in 2.5-inch and 3.5-inch sizes; 2.5-inch variants are typically called portable external drives, while 3.5-inch variants are referred to as desktop external drives.
“Portable” drives are packaged in smaller and lighter enclosures than the “desktop” drives; additionally, “portable” drives use power provided by the USB connection, while “desktop” drives require external power bricks.
File deletion is a way of removing a file from a computer’s file system.Examples of reasons for deleting files are:
Freeing the disk space, Removing duplicate or unnecessary data to avoid confusion, Making sensitive information unavailable to others.
The “deleted” files are not really deleted, but only marked as deleted—so they could be undeleted during some time, until the disk blocks they used are eventually taken up by other files. This is how data recovery programs work, by scanning for files that have been marked as deleted. As the space is freed up per byte, rather than per file, this can sometimes cause data to be recovered incompletely. Defragging a drive may prevent undeletion, as the blocks used by deleted file might be overwritten since they are marked as “empty”.
Undeletion is a feature for restoring computer files which have been removed from a file system by file deletion. Deleted data can be recovered on many file systems, but not all file systems provide an undeletion feature. Recovering data without an undeletion facility is usually called data recovery, rather than undeletion. Although undeletion can help prevent users from accidentally losing data, it can also pose a computer security risk, since users may not be aware that deleted files remain accessible.
