Reliable overwriting of information. How?

Question

Information Security

Hello. A question has come up. It is necessary to erase the file with personal information so that dark personalities could not use it later for selfish purposes. Calm my paranoia, please tell me a program that will do this action according to the latest fashion.

Answer 1

If you need the advice of a paranoid, then the above methods will not help - even a hundredfold overwriting of information can be bypassed by mapping the magnetization of the disk “atom by atom”. It is very expensive, but you understand, the enemies will do anything.
By the way, it suddenly occurred to me that the SSD disk seems to be deprived of such, on the one hand, and, on the other hand, the bad blocks there go into the “read-only” mode, i.e. Some information will never be erased.
Yes, but at the forum of paranoids, in the end, everyone came to the following:
1. Sulfuric acid, injected directly onto the surface of a rotating disk, works ideally.
2. Even the above method will not save you if you are aggressively asked for information.

Answer 3

In FAR, Alt+Del deletes files.

During shredding, the file is overwritten with zeros (you can specify a different placeholder character, see TechInfo#29), truncated to zero length, renamed to a temporary name, and deleted.

Answer 4

If for Windows then:
Freeraser by Codissey
SDelete by SysInternals/Microsoft

Answer 5

The rm utility has the ability to permanently delete on FreeBSD:
man rm
rm -P Overwrite regular files before deleting them. Files are over-
written three times, first with the byte pattern 0xff, then 0x00,
and then 0xff again, before they are deleted. Files with multi-
ple links will not be overwritten nor deleted unless -f is specified
, a warning is generated instead.
Specifying this flag for a read only file will cause rm to generate
an error message and exit. The file will not be removed or
overwritten.
But it all depends on what's underneath

Answer 6

I once used wipe. It seems normal to rub 10 times, randomize names and so on.

Answer 7

Not exactly a program , but there is no doubt about reliability :)

Answer 8

The most reliable option, in my opinion, is to encrypt important files or the entire media. Then at least without your password/certificate of figs that will be able to recover. I used to use DeleteOnClick
to delete .

Answer 10

Unreal Commander, a free analogue of Total Commander, in addition to deleting, has a wipe function, other file managers can do this either out of the box or using plugins.
