The NSA standard was (and still is) 7 writeovers of random data.  Unfortunately,
nowadays, even after 7 writeovers, data can still be extracted.  I believe a
private data recovery service proved that it would take in the range of 15
writeovers of non-random data to leave no trace of previous things on the drive.
