Yes.

That works, I guess (assuming that you completely fill up the drive).
However, I personally feel that it would be better to randomly
generate data (random is always better) and store it on the hard drive
until there is no longer any free space left, then delete the data.
Several cycles of this will make it virtually impossible to recover
any data from the unallocated space. I know of several scripts that
will do this, they're easy to find and even easier to make.
