Make your Recoverable Datas UNRECOVERABLE

If you’ve been following my blog, you’d have known that deleted files can be easily recovered by using a simple file recovery software such as Recuva. When you delete a file, it is not gone forever, and any file removed from the Recycle Bin can be easily recovered! The Windows delete function does not clear the space where the deleted file has been located but only marks an entry in the directory (folder) as deleted. All data and information about the file still remains on the disk and can be restored! Old data will be available until another file overwrites it (uses the same space on the disk). The only way to prevent data from being recovered is to overwrite it.

I’ve seen tools that is able to wipe out hard drives entirely to prevent people from recovering any files and also tools that can delete a particular file and that file can’t be recovered anymore. For the first time I am seeing an innovative FREE tool which is able to scan your hard drive and only make the recoverable files UNRECOVERABLE. Meaning it won’t touch any of your existing files.


Disk Redactor is a WIPE utility that lets you securely erase any old ( deleted ) files and prevent them from being recovered. All your private sensitive insecurely erased information will be wiped from free unused space on your drives to ensure complete data destruction.
Delete Recoverable data

The functions that Disk Redactor performs are wiping all free unused space on your disks, and writing a big file with zeros to overwrite all old (deleted) files on your drive. After using Disk Redactor, all old data will be erased completely without any chances for its recovery.

Only takes 3 steps to prevent your confidential data from being recovered.
1. Run Disk Redactor
2. Use the Wipe Disk button to select the disk you wish to wipe (erase deleted files) and answer Yes to confirm.
3. Wait until the progress bar reaches 100%

It’s free, easy to use and useful. I’ve checked that Disk Redactor is portable. You can simply copy DiskRedactor.exe to your USB flash drive from the program’s folder which is located at C:\Program Files\CEZEO software\Disk Redactor by default.

Please take note that Disk Redactor does not delete an old filenames. You will be able to see the deleted filenames but content of the files will be wiped out and can’t be recovered.

      “content of the files will be wiped out and can’t be recovered.”
      “ensure complete data destruction.”

      Actually it can be recovered. Do a search for ‘encase’ and you will see the scope to the problem. Erasing files beyond all hope of recovery is not hard but its time consuming and this program won’t do it properly. Even PGP did not do it properly until recently (see PGP Bug fixes). By properly I mean government level whose MINIMUM standard (in the US) is 30 passes with 000, AAA, 111 etc and random data. This stops encase and alike recovering anything. If they are really serious about it never seeing the light of day again apparently they then grind up the hard drives to dust. This obviously stops all recovery methods including ‘electron microscopes’ yeah seriously they use them.

      This prog is better than nothing and it’s free but if you have got something to hide, hide it properly and if you haven’t why bother?

      Sorry for being off topic but i really need your help on this.hope u understand the desperation.

      well both me and my uncle’s pc have neto drogon 56 kbps dialup modem.the difference between them is that mine does not make any noise from with in the cpu box i repeat from with in the cpu box(when connecting) while my uncle’s does(speaker make noise which is all right becoz i can turn it off). i have tried everything to calm it down but changing any of the setings does not work. which plug should i be looking to pull from inside the cpu in order to make the connection process quiet?

      A quick response to fred’s post. A program called Eraser employs the Guttman 35 pass method to delete the entire content of files beyond recovery if you’re worried about files on your system. I doubt, very much, if the majority of average users have “government level” secrets aside from potentially embarrassing stuff they might not wish for other’s to view or find.

      And if you’re really wanting to hide stuff, try proven encryption programs which can secure your files or entire hard-drive beyond prying eyes.

      I agree with Rezdog that the majority of users do not have ‘government level’ secrets on their HD’s or I least I don’t. But I do have my bank details on it. I couple of months ago I read about a charity which was collecting old hardware and shiping it to the third world to be used there instead of ending up as land fill. A good idea I thought. Unfortunately the charity was unwittingly giving them to a bunch of criminals who were recovering the HD’s and stealing bank/credit card/paypal details etc.
      Apparently they were very successful at it (in about 1/10 cases they actually got some money). I don’t know what they were using but I am sure they can download commersal forensic software just as well as the next man.
      Hence my ‘Heads up’ about doing it properly. I only took ‘government level’ as a gold standard on the basis that they have almost unlimited resources and more experience/knollege/incentive than any one I can think of. So if they use it its probably as good as I am going to get. I am sure that the Gutmann method is good and probably good enough but its not gold standard as most of the 35 passes don’t do anything as
      they are for old obsolete MFM/RLL encoded disks and Gutmann said so himself (sorry I do not have the reference to hand). I am not saying don’t use it but don’t be dazzled by its 35 passes.

      I hope this prevents a few hard drives coming back to haunt their original owners. I will try to find an app that satisfies my gold standard and post a link.

      The obvious real and good freeware for this kind of product is Eraser. It has a very good trackrecord, and has being ranked top in almost all tests I’m familar with (something most shareware products cannot say)

      Everyone knows that. Why settle for all the other crap?

      This three pass wipe probably prevents most data recovery and no additional programs are required.

      Cipher.exe Command-line Utility

      The Cipher.exe command-line utility may be used to overwrite deallocated file clusters on the NTFS disk to reduce the risk of discovery of plaintext shreds left over from file conversion. Cipher.exe /W makes three disk write passes on all unused clusters on the disk. The first pass writes 0. The second pass writes 0xF. The third pass writes pseudorandom data.

      CIPHER /W:directory
      /W
      Removes data from available unused disk space on the entire volume. If this
      option is chosen, all other options are ignored. The directory specified can be
      anywhere in a local volume. If it is a mount point, or points to a directory in
      another volume, the data on that volume will be removed.
      Note Cipher.exe wipes all deallocated files from the specified disk even if a specific folder is named. It may not be possible to wipe files smaller than 4K in size as they may exist in the Master File Table (MFT) and not in separate clusters on the disk.

      To run Cipher.exe

      Log on as an administrator of the local machine.

      Close all applications.

      Open a command prompt by selecting Start, then Run, and entering CMD as the command.

      Type “Cipher /W:” (without the quotes), where is any directory on the drive you want to clean. For instance, “Cipher /W:c:\ ” will cause the deallocated space on the C: drive to be overwritten.

      Cipher.exe will begin running, and will display a message when it’s completed.

      Important Cipher.exe /W may take a very long time to run, especially on large volumes. It is not possible to stop it once it has started. Running the chkdsk.exe command on the volume after completion is a best practice. Also, it is not recommended that the cipher.exe /W be run multiple times; the intent of the process is a one time cleanup of the disk. Note NTFS drives can be mounted as directories. For instance, a drive could be mounted as C:\folder1\D_Drive. This usage enables drives of this type to be cleaned.

      The new cipher tool is also available for Windows 2000 by downloading from the Microsoft Web site: http://support.microsoft.com/default.aspx?scid=kb;EN-US;298009&sd=tech

      file shredder has an option to shred free disk space using different algorithms. its free and is also googleable. check that out. i am using it now to make my hard disk files unrecoverable before giving it back to a friend.

    • somalia

      sonata also works well . sonata free shredder is also anothe rfree ware that seems to have a powerful shredder. try that out and let me know people

      COMMENT: writing a big file with zeros to overwrite old data or “ZERO FILL” as its called is a good way to erase data from those that don’t know how to recover things. in other words it doesn’t do anything to help protect you from theft of data should someone that wants your data actually get their hands on your drive. the only way to safely erase data is to use a program that supports different wipe standards like DOD, gutman, etc.

      what i suggest for if you really have something to hide is use Active@Kill Disk. it has single pass up to over 30 pass zero fill and random data, and custom mode where you tell it how many passes you want. remember that high security takes time so don’t expect it to be done in a few minutes.

      the best way to make a harddisk unrecoverable is physical destruction..

      second is degaussing

      third is the gutman 35 passes.

      you want proof. use your wipe a** softwares then bring your hard drive to NSA nad you’d be surprise.
