What type of "sensitive information"?

 

Formatting the partition removes all files.

 

We need more details on just what it is that you refer to...and why you want to remove it from the system.

The only 99.(99)% sure way of removing the information from existence is to burn the HDD 2-3 times over and spread the burntout flakes in the ocean lol. :lmao:

Seriously though, if you want to remove the information, format your HDD and then format it once again. :)

suzie1961:

 

There is a free program, called Eraser, that I use and which will shred any files or folders that you select, such that they are unrecoverable.  It is very useful for deleting files and folders.

 

If you want to make all files on your hard drive unrecoverable, then, as already suggested, a full format should do the trick, if repeated a time or two.

 

Of course, for complete security, a sledgehammer, repeatedly and forcefully "introduced" to the hard drive, will permanently render all files on the hard drive unrecoverable! :smash:

 

Have a great day.

I borrowed a laptop from someone, and i want to remove  my browsing history from a website that i use, and any information related to the particular site, because there are certain things i do not want to be seen by anyone. To cut a long story short, i previously done work as an escort and i used a particular site to advertise, and i do not want any of this information showing on the P C , or any of the browsing history etc,

 

Thanks

Clearing browser history is a simple issue.

 

For what you're proposing, as well as wiping the hard drive, I'd suggest using Piriform's CCleaner.  The regular cleaner option removes browser cache and history.  There is also a function that allows you to wipe free space, and it will do multiple overwrites to ensure that the data in free space is actually removed.  I've used the free space wiper of CCleaner to thoroughly purge all data that was not related to the OS on a couple of machines.  One of which was to clean a machine before it was donated after the death of someone who had, shall we say, eclectic tastes that his estate executors wanted to make sure remained their knowledge alone and, other than them, to go to the grave with him.  It works.

Depending on the browser you are using, these steps might be named differently:

1. Start your laptop
2. Open you browser (Mozilla Firefox, Edge, Internet Explorer, Chrome, etc.)
3. Find somewhere on the upper side of the screen 'History' and open it.
4. Find somewhere either 'Show full history' or 'Delete history'. If you don't find it, check in 'Settings/Options' instead. It will be there
5. When the screen about clearing your history opens up, mark everything and click on 'Delete/Clean'
6. Close your browser
7. Download CCleaner from here - it is a quick cleaning tool
8. Install CCleaner
9. Open CCleaner
10. Run CCleaner
11. After you've quickly run & cleaned the computer with CCleaner, uninstall CCleaner from the Start menu
12. Open your browser again
13. Delete your whole history again just to be sure
14. Close your browser
15. Restart your laptop
16. Congratulations, the laptop is now clean of any evidence and history, which can't be found by anybody else, but a professional, which means that the person from which you've borrowed the laptop won't be able to find anything, even if he tried to!
17. That's it!

P.S. Bear in mind that this will delete every bit of history and searches, and browsing you have done on the Internet. It will also delete all paswords as well, so make sure to keep this in mind!

If one uses any utility to erase free space, I highly recommend a full image of the OS partition and Data partition is made onto external media [in this case, backups kept by the computer-borrower]; and during the erase free space operations, I think, IMO, it is best to not heavily use explorer.exe or anything that will do lots of read/writes.  Reason for warning:  I saw a thread somewhere some time ago that indicated an erase free space operation went wrong and deleted data -- of course that could have been caused by any number of user-error, or utility error, or whatever.

...Taking the basic stepsdeleting data from or reformatting a computer hard drive, or doing a factory reset on a smart phone or tabletmight be enough to discourage identity thieves. But this approach is far from a guarantee, and it wont stop someone whos specifically after your files, accounts, or photos.

MIght want to research Darik's Boot and Nuke, AKA, DBAN....

Use with extreme caution, you zap the wrong drive in a system with multiple drives, your data is GONE!!!!!!!!!

 

You can specifiy 1 pass, 3 passes, etc...

 

While deleting partitions and quick formatting will perhaps discourage Uncle Joe from perusing your saved old incriminating anime photos, it does not truly get rid of the data until written over thoroughly.... at least once!
