DBAN questions, is this an error?

by bthlp / August 21, 2013 3:30 PM PDT

Ok so I was wiping 2 drives on 2 different computers

Both 7 passes, I have another 3-4 hard drives I have to do

My question is what if I were to do 1 pass SEVEN times, will that be considered "7 passes"?! What if I were to do TWO 3 passes, would that equal 6 passes?

I don't see any error.

I've never used more than one pass.

Even a single pass is more than sufficient unless you have access to a billion dollar forensics lab.

Why so many?

1 pass is enough

I have always done 1 pass and it did the job. On top of that repeated passes on large HDs do take time. The military(DoD) spec is 5 passes, FYI. There maybe others suggesting more, but intense 1/0 writing can tax a HD so be careful, you may actually break the HD under intense usage.

Dban succeeded

If I remember right, I've always done DBAN on 1-HD installed in the system. Disconnect all others and if this is the actual 2nd HD, make solo as if only on port 1, etc.. Doing so, helps defeat the error popping-up but I urge trying this before trying anything else. Plus, the error probably is more of a procedural one than a h/w fault.
