opinions about BCwipe and other wiping software

dd (or a variant thereof)

dd if=/dev/zero of=/dev/hda bs=1M

Where hda (or hdb or hdc or …) is the drive you want to zero and bs is the block size. You can do this with pretty much any nix Live CD.

DBAN is another easy solution.

If you care for time I believe you should turn to hardware erasers.

Of course we talk about completely different money, but wiping a lot of media with a hardware wiper certainly provides a nice ROI 😉

To the OP just want to confirm that you would like to re-use the drives correct?

Yes, I want to reuse these HDDs. I am referring to the HDD installed on my computer. One can´st be using DBAN nor BCWIPE Total, once a week, each time you delete a file…

By the way What happens with disabling restore points(system recover), recommended when one is deleting and wiping files, BUT when you are deleting these files into a truecrypt container, which as you know, truecrypt needs restore points. Which software use in these cases. sdelete seems not to have problems with that issue but, are there other ones?

we use mediawiper made by a company called white canyon and it works very well. it is not free though but maybe you can download a trial version.

NIST have tested some of the tools and found that some tools miss overwriting areas.

Unfortunately, they are closed at the moment because of some pricks who think it is more important to levy their sociopathic political agenda than to have a working society.

Uh-oh. 😯

NIST Closed, NIST and Affiliated Web Sites Not Available

Due to a lapse in government funding, the National Institute of Standards and Technology (NIST) is closed and most NIST and affiliated web sites are unavailable until further notice. We sincerely regret the inconvenience.

A snapshot of the site (Feb 2013) is available through the Wayback Machine (should be these the referenced documents)

They will, all get back-pay, when returned. Some are already collecting unemployment funds. There is no mechanism to pay back unemployment, once they get their back-pay. Sounds like a vacation with a bonus, doesn't it?

The reason there is a market of vendors and websites of hash databases and test results is because NIST failure in the last decade to work.

Kanguru makes a 14 drive bay duplicator/wiper for around US$5.5K.
