Wiping Win2000 partiton

Hello,

I am running W2K and want to clean a partition of all the remains of
all deleted files.

I wiped it using BCWipe, with 7 writeovers, and with the Disk Scrubber
v2.1.

Both applications work from within the W2K GUI.

Then I downloaded a demo version of an application that recovers
files, and it found most all of the files, even though the partition
had been wiped by two different applications.

Question: Does Win2000 allow wiping? Or does one need to boot from a
DOS disk, and then wipe?

The drives and partitions are NTFS.

Thanks in advance.
