There are some techniques for recovery of wiped data. The latter also conceals the fact that you wiped the data. So if you want to protect your information from a casual snooper, you may safely choose either theĪlgorithm. All of these wiping algorithms make recovery of wiped data with any software-based data recover utility impossible. What algorithm is to choose, depends on your specific needs. This algorithm is military-level secure, but horribly slow. Provides high-grade data wiping by filling the file with a special digital pattern through 35 passes. This algorithm is very secure, but very slow. Provides high-grade data wiping by filling the file with a special digital pattern through 7 passes. The file is wiped using Department of Defense standard 5200.28-STD(7). Provides high-grade data wiping by filling the file with a special digital pattern through 3 passes This algorithm is very secure, but slow. The file is wiped using Department of Defense standard 5220.22-M(3). ![]() A slower but little bit more secure algorithm than theĪlgorithm and it also conceals to some degree the fact that the disk or file has been wiped. The file is filled with pseudo-random numbers through 1 pass. Also it does not conceal the fact that the disk or file has been wiped. ![]() The fastest but the least secure algorithm. ![]() The file is filled with zeroes through 1 pass.
