VSITR
The VSITR standard of the German Federal Office for Information Security (BSI) prescribes overwriting of contents to be deleted on hard drives 7 times. VSITR stands for guidelines for secrecy protection of classified information when using information technology.
The standard is no longer valid and was replaced by a new deletion standard in 2009. There are various software that erases according to the VS-ITR standard. For example VS-Clean (from BSI), HDShredder, Certus Software, Blancco Software or DBAN / EBAN (Open Source). VS-Clean is now out of date. Approved alternative software recommended by the BSI can be found in BSI-TL 03400 in section 5.4.
