Is the 35-times overwriting of the data safe? Can any human recover the data?
I did not want to include data overwriting up to 35 times in " SafeDelete
", but some users insisted on this feature. Since it was not a big hassle for me, I just integrated it.
Whether 1-35 times usually does not matter!
As a person you tend to consider things that are repeated more often than safer. Similarly, deleting is just a psychological effect that we humans often need.
But in this case, it is exaggerated security and a waste of time .
It's like having a glass of water. If you have completely emptied this time, then it's just empty. You can always try to drink from it and see if something is inside, but it still remains empty.
Attention SSD and network multiple duplicate files!
Rather, the question arises whether the data may not be stored elsewhere. This would be true if in the background a software, such as a backup program is in operation, which permanently stores the data on another computer and possibly even logs all changes.
* SSD does not always allow secure deletion by controlling file storage!
Reliable deletion and overwriting of data is not always possible in the conventional way.
* Files in the buffer / RAM! A restart of the PC is also recommended the duplicates can also be located in the intermediate memory!
PS:
Some data is so sensitive that you can not use it if you miss a single bit in the wrong place. This is the case with 7-Zip archives. That is also the reason why 7-Zip should only be used as a backup program.
Except the data is not that important, but who secures even unsafe data.
With Zip, the loss is not so big, you may lose ~ 32,000 bytes in the loss of 1-bit. Which is not without, but at least less, with 7-Zip it can sometimes be here with highest compression over 100 MB and more. I do not want to say you should not use 7-Zip, but you should think about it.
In 7-Zip there are also other options to increase the security of the data, but then it is not so effective in compression. Safety has its price :-).
Info:
7-Zip is still a very good program that has very high compression and is in many ways very useful.
Does not have much to do now with safe deleting but with the security of the data.
So, sure deleting is not art.
Deleting by multiple overwriting no longer brings security. Whether with random data or with zeros does not matter either.
