I have two used 40GB Maxtor IDE drives that are in good condition, both of which I removed from existing older single-drive machines, and replaced with larger capacity units. The Maxtors were single partition NTFS C:\ drives, and contain their original data. I want to wipe them for reuse without destroying them, and give them to a local charity. I read that DBAN works well for this sort of operation. If I understand correctly, all that is necessary is to install the drives in any machine with all other HDDs removed, boot from the DBAN floppy, and the drives will be securely wiped, but still be good to use (reformat?). There will be no effect on the machine's existing BIOS settings. Is that correct? Thanks.
