Programs to delete data is very much. Their effectiveness depends primarily on the algorithms used overwriting. Popular and very effective is the Gutmann (the description on: www.usenix.org/publications/library/proceedings/sec96/full_papers/gutmann/). Many of the tools used to delete data or the algorithms in accordance with the guidelines of the U.S. Department of Defense for the protection of classified information (for more on: http://en.wikipedia.org/wiki/NISPOM). 
In both these solutions use a free program Eraser (www.heidi.ie/node/6). It allows you to delete both individual files and directories and entire drives (after running the external media). It also supports portable memory (flash memory and CD / DVD RW). Since the system supports FAT32 and NTFS, so it can be used with all versions of Windows. Its advantage is that open source code (GPL). The program was evaluated members, thus ensuring that it is effective. This can not be said about the application of closed source, especially if they are not products of reputable companies.
For erasing discs can also be used as an independent program for creating bootable media for erasing discs, without activating the system, such as Darik’s Boot and Nuke (http://sourceforge.net/projects/dban/). Chicago erase data, New York erase data, Detroit erase data, Houston erase data, Los Angeles erase data, Philadelphia erase data, Phoenix erase data, San Francisco erase data, Washington DC erase data, San Jose erase data, Seattle erase data, Austin erase data, San Antonio erase data, Baltimore erase data, San Diego erase data
Erasure Linux
In the case of Linux for the effective removal of files you can use the shred command, accessible from the command line. The process of removing data at the standard parameters of the program (command: shred-u FileName.txt) is a 25-fold overwrites the space occupied by the file. Alternatively, you can use the package secure-delete. In addition to tools for removing files (SRM) can be found in the program to clean RAM (smem), cleaning of free space (sfill) and swap space (sswap).
In professional applications, eg for erasing discs in large companies and institutions, we use commercial software such as Ontrack Eraser. Its advantage is to generate a detailed report of the deletion. It allows you to assess the effectiveness of the process and can be attached to the hardware documentation. The program is available as a Windows application and a bootable Linux minidystrybucji.

Fortunately, effective erasing information from the flash memory is easier than for disks. Because they are based on the electronic record, and not magnetic. So there is no problem with memory-effect of the media and inaccurate work head. Therefore, even once to overwrite the data cells causes irreversible loss of the previous information. Please note that as with the effective disappearance of the disk media requires overwriting each cell in the medium. We provide shredding data service in all cities of Chicago data shredding, New York data shredding, Detroit data shredding, Houston data shredding, Los Angeles data shredding, Philadelphia data shredding, Phoenix data shredding, San Francisco data shredding, Washington DC data shredding, San Jose data shredding, Seattle data shredding, Austin data shredding, San Antonio data shredding, Baltimore data shredding, San Diego data shredding,
Flash Disks and flash memory cards too easily destroyed. Because this memory is a very complex, multi-layer circuit, the irreversible destruction of the media, even small enough to breach the structure. And how is the situation with CDs / DVDs? You can destroy the media, such as breaking it into several parts. If you want to delete multiple record on the media CD / DVD-RW, use the application to remove the data that supports this type of media.

To effectively get rid of private information, you must use software that physically removes the record from various sectors of the magnetic disk. The hardest thing to get rid of the data from your hard drive. To do this you must physically overwrite all the data bits on a medium random string. Unfortunately, A single operation is not sufficient to have 100 percent certainty. Due to the specificity of life once overwrite magnetic media can not guarantee that each cell effectively replaced all of the information. It may happen that the head inaccurate information and wrote the new cell, you can also read the old data.

Certainty gives only overwrite each cell 4-5 times. If you erase individual files is not a problem. But when you clear the entire disk, for example, before passing it to the new owner, this process can take up to 9-10 hours. To effectively erase the disk, the program to destroy the data you need to start from the USB flash drive or CD so that it can get to every disk sector. This is impossible when the pc runs locally installed operating system.
Effective destruction of data
* Hard Drives
repeated overwriting every sector with the Eraser or destruction of discs
* Flash Memory Cards and Flash Disks
overwrite the data once the program Eraser, or physical destruction of memory chips
* Motherboards Optical CD / DVD
destruction by breaking into three pieces
Delete using applications lasts a long time, so you can not use it when you need to quickly destroy the data from multiple drives. Such situations occur mainly in companies and government agencies for the exchange equipment. The most common method of destroying data from a disk is to treat the strong electromagnetic pulse that causes the destruction of not only the magnetic recording, but also the entire consumer electronics (see also “Expert”). Unfortunately, after such a hard surgery is suitable only for disposal.

Permanent delete data
As is clear from the analysis of second-hand hard drives bought on auction sites, most of which contain private data of the previous user. Their owners did not know that formatting the media does not delete any information. Although the vast majority of cases the contents of disks has been deleted, but users have done this by simply reformatting the media, which only clears the file allocation table. Physical record in the various sectors on the hard disk during this operation not in violation.

Recovery of data that still remain on the plates in the form of magnetic recording, there is no problem. You do not need even a specialist laboratory.
