I never realized that one overwrite and the file would be completely destroyed. For sensitive date, i have always done at least three overwrites.

Whilst i appreciate HDD’s have evolved over the years, what exactly is it that makes one overwrite so effective now?

The rm command built into OS X has a -P option that does a 35-pass truncating renaming secure delete. srm has a few more options, including a nice -s option to make it go 35 times faster.

There is no reason to do more than one overwriting pass on a file. Any more than that is absolutely pointless. Way back when, when hard disks were 6 ft wide and held a few hundred KB, when Guttman’s paper was written, things were different.
