SDelete and CopyWipe: Software to Permanently Delete Files

When it comes to deleting files, the simple truth of the matter is that even if you press Shift + Del, or click “Empty Recycle Bin”, that data is not actually deleted; the file space is merely “deallocated” and someone could easily bring those files back to life – it is only when said data is overwritten that you can say it has actually been deleted. Following the Recuva 1.21, the data recovery tool that will bring your deleted files back from deletion, and RightDelete, the tool that will safely delete files, I would like to present you with some other applications that you can use to ensure no one will be able to bring back your deleted files.

The software programs I wish to draw your attention to are SDelete and CopyWipe. The Microsoft developed SDelete works by overwriting the free space on your hard disk , and does so in a simple command line manner (did I mention that it is free?). Copy Wipe can be used to permanently delete all the data content included on the hard disk (or just a partition), or it can be used to move data from one partition to another (or from one HDD to another).

“SDelete is a command line utility that takes a number of options. In any given use, it allows you to delete one or more files and/or directories, or to cleanse the free space on a logical disk. SDelete accepts wild card characters as part of the directory or file specifier,” explains Software Engineer with Microsoft, Mark Russinovich.

“CopyWipe can ease and expedite the transition to a new hard drive by copying the entire contents of one drive to another. CopyWipe can also help prevent confidential or private data from being recovered, by securely wiping the contents of a drive. A number of options are provided for wiping, most of which exceed governmental standards (such as DoD 5220.22-M, NAVSO P-5239-26, etc.); this allows the user to choose an optimal balance between security and duration of the wiping operation,” explains TeraByte Software.

Now if you would like to migrate data from one system to another, you might want to try Easeus Disk Copy 2.3.
