Reformatting the drive and zeroing are two entirely different things. When you zero it, it should be replacing the data with other data making it impossible to recover. When you reformat, nothing is being over written, it is just being marked that it CAN be over written with files at a later point.

i know the difference between the two, but your average person (probably average OCNer too) wouldn't know the difference. that's what the post was directed towards.

Well, the original post and the argument thus ensuing was about the validity of a one pass zero fill, so the you presented actually didn't back the claim of an ineffective one pass.

The research I have done makes it seem that a one pass zero fill is virtually impossible to retrieve data from. Plus I don't really have anything too sensitive on here, so I think the one pass will work fine for me.

Of course you can recover everything from a quick format. That has absolutely no relevance to the question at hand.

my apologies. i'm used to people saying wipe but meaning format. i recant my original statement and will save it for a future argument.

One pass is fine for this use.

No recovery companies claim to be able to recover data that has been over written, even with a single pass.

More importantly, no one buys hard drives off craigslist with the intent on spending thousands of dollars per drive in an attempt to recover data. If cheap recovery software can't recover it, virtually no one is going to both looking deeper, unless they are trying to put you in jail, are being paid a fortune to keep you out of jail, or think you are selling national secrets.

Single 0 pass is fine.

Very few people have electron-microscopes + associated data for reconstruction + lots of free time + box of care.
