Rubbing reliable information. What?

If you need advice paranoid, the above methods do not help — even hundredfold mashing of information can be circumvented by making a map of the magnetization of disk "poutana". It will cost a lot, but you know, enemies will do anything.
\r
By the way, suddenly thought that SSD like such a deprived, on the one hand, and, on the other, the bed-blocks, there is transferred to the mode "read-only", i.e. some information will be impossible to erase — ever.
\r
Yes, but the forum is paranoid in the end, all came to the following:
1. Perfectly valid sulfuric acid, is injected directly into the surface of the rotating disk.
2. Even the above method will not help if the information you have will be aggressive to inquire.

In FAR Alt+Del is executed destruction of files.
\r

In the process of destroying, the file is overwritten with zeroes (you can specify a different fill character, see TechInfo#29), truncated to zero length, is renamed to a temporary name and then deleted.

If Windows, then:
\r
\rFreeraser from Codissey
\r
\rSDelete from SysInternals/Microsoft

Utility rm has the ability to delete "firmly" on FreeBSD:
\r
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 speci-
fied, a warning is generated instead.
\r
Specifying this flag for a read only file will cause rm to gener-
ate an error message and exit. The file will not be removed or
overwritten.
\r
But all depends on what bottom

When I used the wipe. Like normal rubbing 10 times, randomized names and so on.

Not exactly a program, but the reliability cannot be doubted :)
