Secure delete


Recommended Posts

That would be an excellent feature. Now that the eraser has been written, that seems like it would be a fairly simple addition. Maybe in version 1.28?

Hi

 

Can anyone explain how this tool works and what different options means.

Hehe, that's not quite what secure file deletion is but I bet the government uses secure file deletion :)

 

Those options select how you want to securely erase data from your hard drive so you can't dig them back up. Typically when you delete a file from your hard drive, instead of actually erasing the data, your computer just deletes the reference to it and marks it as free space. This gives the user the illusion the data is gone but in reality it's just sitting there still intact, just not visible.

 

The way secure file deletion works is by writing random data over the area where the deleted file is. Even then if someone tries hard enough they can dig up that information. That's why different methods write random data over the deleted file multiple times (indicated by the number of passes listed next to their name). The different types of secure file deletion you can choose from just determine how secure you want to be by saying what type of random data to write over the deleted file and how many times you want to do it.

Hi

 

Thanks for your answer.

 

- "Passes" is then number of overwrite times. OK

 

- "saying what type of random data", is also cryption used ? ref mil and NSA

 

Ongoing discussion within a swedish forum about how to translate it and also explain how it works. :)

I'm going to be picky, how about these suggestions for renaming:

 

Simple Overwrite (1 Pass, Fast)

DoD Short (3 Pass, Slow)

DoD 5220-22.M (7 Pass, Slower)

Gutmann Wipe (35 Pass, Slowest)

Custom...

 

Notice the last two I added don't exist yet, its a hope for the future... custom erasing would be nice. :)

 

If there was gutmann, custom erasing, and right-click erasing like eraser... well there wouldn't be any need for eraser.

Excellent idea! I totally concur. Maybe you should PM MrG with that suggestion; if you had a Custom option, MrG would really never have to tweak the erasing aspect ever again, even if a new number of overwrites becomes the standard.

There's no Gutmann?? We definitely need Gutmann wipe. Come on...

Sorry, but I still don't understerstand.

 

What is exactly a RESULT of checking f.ex. NSA (7 passes)? What have I to do when I want to delete files (or directory) by NSA procedure after checking it in CCleaner?

 

 

- when I choose file(s) or directory(ies) by clicking right mouse button and then I choose "Delete" from context menu IT MEANS that choosing files will be deleted by NSA procedure? IT MAENS that CCleaner have not be turned on to delete files by NSA Procedure, if I earlier checked option mentioned above?

 

 

Please, answer me.

Thank's in advance

All that CCleaner overwrites are files that it normally removes. In other words, if you have the overwrite feature turned on in CCleaner, and then click "Run Cleaner", every file listed is overwritten however many times you select.

 

It DOES NOT mean that deleting a file in Windows will overwrite it. Windows does not overwrite files, and CCleaner only overwrites files that it cleans, such as cookies and logs. If you want normal files overwritten by CCleaner, instead of simply deleting them with Windows, you can put those files in a folder and then add that folder to CCleaner's Custom Files and Folders list.

OK. I understand now. I think that will be good to add in options f.ex "Secure deletion files in CCleaner procedures" or something...

 

One idea I had recently was to have a button on the left side called "Secure Delete" and when you click it, there would be a blank box that you could drag files into to securely delete them. Something along those lines anyway.

Ok. Thanks for an answer.

 

I have one more question. I use CCleaner very often. And i'm very satisfied. But sometimes immidieately after CCleaner I use portable (for USB) pack of Norton System Works 2006 (inside is only Windoctor and DiscDoctor) too. And I wonder whay almost ALWAYS WinDoctor can find some problems (with shortcuts, with registry or something like this) left by CCleaner :(...

Use a dozen different registry cleaners, and you'll find a dozen different entries. When it comes to cleaning your registry, there are hundreds of entries that are useless due to uninstalling software, file extensions, etc. What one program finds, another might miss.

 

CCleaner, while powerful, isn't a very aggressive registry cleaner. This is because it is made with safety in mind. Instead of finding any issue that could possibly be necessary or unnessary and marking it as useless, CCleaner only removes items that you can be certain are unneeded.

 

That is why, if you were to run an app such as Norton Systemworks or RegSupreme Pro, you may find more issues. These scanners may be more powerful, but they are also potentially more destructive to your system, if they find and remove an entry that may end up being necessary.

 

MrG improves the Issues scanner with every version, so as more CCleaner updates come out, those other registry scanning apps will eventually not even be necessary.
