Yes mate I guess nothing is really that safe anymore because of the tech stuff you have quoted. I suppose one can just hope a clean / wipe does a reasonably good job at stopping the previous install from corrupting the next one as I mentioned I am not a fan of simple formatting.

Maybe I am wrong but it is something I do advise members in the forum who are not familiar with such stuff to do the same.

So I would like to know what anyone advises in that scenario??
If the intention is to reuse the drive yourself, a Clean All is perfectly OK - nothing else is required.

If the intention is to give the drive away or sell it, and it didn't have sensitive information : use Cipher or SDelete.

If it had sensitive information, physically destroy it.

Whilst its relatively easy to recover information from a drive that has been formatted, it's considerably more work for a drive that that has had a cleaning/wiping algorithm run over it. Just like Dariks Nuke and Boot, Eraser and others, both SDelete and Cipher write random data across the disk in a number of passes - the time and effort required to reverse all of that is considerable. The only people prepared to do that, need to have some compelling reason for it ie. security agencies. And they only do that when its worth their time and effort.

Thanks Colin that is just what I do myself not having anything worth while on my drives I just like to know the previous install has been fairly well wiped off so not leaving much if anything behind from the previous install.

I do in the forum when I have been on threads that have bad installs always ask how the drive was prepared before the member re installs the OS (any OS) and almost every time they have just formatted a practice that I mentioned I don't particularly like preferring to clean the drive, and in any case both methods are reasonably quick to do.

I am not sure if I should be doing that so what would you advise them to do before a clean install?

I know we don't like to direct users off this site but this article explains better than I can about secure file deletion.

How to: Delete Your Data Securely on Windows

See sections on SSD's.

Also note: I personally use and currently have installed:

Ccleaner + CCEnhancer
Bleachbit
SystemNinja
PrivaZer
Nirsoft CleanAfterMe
ShellBag Analyzer & Cleaner
JPG Cleaner
Blank & Secure
sDelete

However just going ahead and running a full cleanup with all settings checked could lead to problems which are hard to undo.

I don't have anything much to hide but there have been certain documents stored on my machine that if recovered could be used in identity fraud or to transfer money from my bank account.

I remember some years ago that I found evidence that my machine had been hacked and all my documents had been uploaded to who knows where in a zip file all without any sign of anything amiss!

EDIT: If you read that article it also mentions Bleachbit.

BleachBit can wipe the traces Internet Explorer leaves behind using the Internet Explorer preset (however BleachBit cannot wipe traces from any other browser).
Actually that's not correct. If you download winapp2.ini it will add other browsers cleanup.

Also if you trim winapp2.ini in CCEnhancer you can just copy and paste it into other cleaners but my preference for other cleaners is to do a full scan and inspect results removing anything that actually needs to be kept from the detections before running a cleanup.

winapp2.ini in Ccleaner is trimmed in the screenshot.

Thanks Callender that was a good read and I also went through the Ask Ars article too I found the comment at the end of it really quite witty

And finally, lest we forget, there are many more violent options if you don't intend to reuse the drive. Pulverization and pyrotechnics are both quite reliable.
Well the SSD info was really an eye opener for me and I suppose for me it raises the question as to whether I should be encrypting the drive I use - not that I have anything to hide apart from my stored passwords etc.

As for what we advise members to do and I speak of those who admit to being not very literate with a machines hard or software, I am no longer comfortable with what I have been putting out there. For myself I am happy to clean a drive instead of just a format only because I can and do have the resources and funds to replace any drive that I may wreck.

Having said that according to this Wear leveling - Wikipedia the wear leveling depends (if I am reading it right) on what type of flash memory is being used ie if it is a SSD or stick - static or dynamic wear leveling. Plus I have seen in adverts for SSD's the number of read/write cycles that are available and by that I think it means the rate of wear to the different blocks. Whether the companies quoting those cycles in the millions of (cycles) is or may be a point of appeal (sales prompt) to the buyer and in reality not quite correct let's say.

I guess in the long run for an average user like myself you would be pushed to actually wear a drive out say if it were 250GB or more and I can understand that heavy gamers or servers would be more likely to wear the drives to useless. But I stand to be corrected on anything I have typed up here.

Anyway I shall look at some of those softwares you have on board because I have recently been looking at testing some softwares from the Gizmo site before using them and making myself a diagnostic USB stick I can use on families machines - or my own

RE: Your problem with Ccleaner and CCEnhancer.

If you don't trim the winapp2.ini file before running CCleaner it will become very sluggish. It should still work though!

However if for some reason Ccleaner hangs - end process via task manager. Relaunch CCEnhancer and select option to trim winapp.ini the download latest definitions.

Once update is complete choose option to run Ccleaner but only select Analyze and check the results.

Items in the left pane with an asterisk (*) have been added by CcEnhancer.

I reckon you might need to disable any Ccleaner real time monitoring before updating. Can't say for sure because I don't use Ccleaner real time monitoring.

Ok mate I will give it another try I did see that stuff about the winapp2.ini file when I got the Enhancer download up but thought that as clicking on it didn't do anything it would do whatever with it by default. So that is my mistake I guess.

The CCleaner actually stopped dead in the water and the Analyse was "greyed out" so to speak when I installed the Enhancer hence my resorting to a system restore.

Well if you update the winapp2.ini file using CCEnhancer you really need to select the trim option first. Then it only loads cleaners that are needed for your specific machine. Otherwise it will load a huge list of everything thats included in the default winapp2.ini file.

You can directly download it and view it with your text editor from here:

Downloads - Winapp2.com

If you compare contents and file size with a trimmed winapp2.ini file you will see a huge difference. The lag in Cccleaner is because it's checking every entry in the file and it might take 10 minutes or more before the program starts responding. With a trimmed winapp2.ini file it should only take seconds to load the results.

It's much easier to use the trim function in CCEnhancer that using the batch file trim method. I've used both.

Other than that if you still get problems - I remember having a problem some time ago with Ccleaner hanging and the fix was to fully uninstall it then download and install a fresh copy. I think just applying updates straight over the top of the old version can eventually lead to problems.

Hmm Callender am in a right pickle here I have tried just about everything and still am getting the "greyed out" Analyse in CCleaner when installing Enhancer.

Now I am assuming I am doing something really quite wrong here and the ini file is not being shown in Windows / Program files / CCleaner / search for that ini file - no results.

Now I saw you are using some software called Swift Search and I went to download it and my Kaspersky is bouncing it as possible malware included so I am at a loss now.
