The easiest and most reliable is to use dd. Livecd-tools is also reliable

Is there a utility to zero unused blocks on a disk?

I saw zerofree, but I’m not sure it would work on Ext4 or even work on this
version of CentOS.

Personally, I just do 'dd if=/dev/zero of=/path/to/zero.img bs=1M; rm -f
/path/to/zero.img'. It's inelegant, for sure, but it works (note to run
it as a normal user or else be careful of how your system reacts to
running out of disk space for a moment).

Wes didn't say the
hdparm supports ATA secure erase. This is SSD safe, unlike other options.
It's faster than writing zeros to both HDD and SSD.

DBAN is obsolete. NIST 800-88 for some time now says to use secure erase or
enhanced security erase or crypto erase if supported.
Other options do not erase data in remapped sectors.

dban doesn't? What F/OSS does "secure erase"? And does it do what dban's
