Helpful tip -- the command line format command on Windows 7 and above allows you to write zeroes to the new drive.

FORMAT <drive letter:> /fs:ntfs /p:1

/P:count Zero every sector on the volume. After that, the volume
will be overwritten "count" times using a different
random number each time. If "count" is zero, no additional
overwrites are made after zeroing every sector.

It doesn't sound like it will always be zeros, but rather a random number each time for the /P parameter.

Thanks for the tip! Might come in handy when I need to shrink down some Windows virtual hard drives. I've been using sdelete from Sysinternals to zero the free space to compact the virtual hard drives. This will save me from a package install. :)

It says the /p option is the "count", or the number of times to write, not the actual value to write. So /p:0 would have it write to the drive 0 times, or basically do nothing.

That options sounds to me like it zeroes the volume first, then writes the random values. So "/p:0" would just zero the volume. No?

Ah, yes, that sounds right, after I read it again.

That's how I've read it. Anyone actually tried it to see?
