Undeletion Features Does Not Work need Hard Drive Recovery

If you have intentionally or unintentionally removed your critical files from your computer system, you can restore them using Undeletion feature of your file system. Deleted files and data could be recovered on many file systems, but not all the file systems offer this feature. Salvaging lost data and information without using Undeletion feature is known as data recovery. The Undeletion feature protects your files from accidental data loss.

Support

Undeletion feature is included in a number of file systems but it is not supported by all operating systems. This feature is supported by DOS (Disk Operating System) but isn’t supported by most of the modern UNIX file systems. Ext2 file system of Linux operating system has an add-on tool known as e2undel that allows users to undelete the lost files.

GUI (Graphical User Interface) environments generally take a diverse approach for Undeletion by bringing in a “holding area” for the files and directories to be deleted. The deleted files and folders are moved to this area and all the files in this area are periodically removed. This approach is known as Trash Bin in Mac OS, Deleted File in Novell Netware and Recycle Bin in Windows. This approach isn’t subject to the issue that other files and folders being written to file system would disrupt the deleted ones. Permanent deletion would occur on predictable schedule or with manual interference only.

Limitations

Although, Undeletion is an important feature to minimize the risks of permanent data loss, but it has following limitations:

In such situations, to recover your lost data, you need to opt for data recovery software. These software are powerful tools that systematically scan the whole hard drive and extract optimum data from it. They are fairly easy to use and enable you to have ‘Do It Yourself’ hard drive recovery.

Stellar Information Systems Limited is the leading provider of most advanced and power packed data recovery software. These software are available for Windows, Mac OS, Linux, UNIX and Novell Netware operating systems. The software are usable with all file systems, which are compatible with these operating systems.
