I am curious. I have a ton of NVME disks that need to be wiped for re-use. They had McAfee EPE on them. This resulted in EFI formatted disks with the FAT32 EFI partition, an MS partition, and the rest was a McAfeeEpeReserved partition. I noted that using "blkdiscard" would not work, so I ran parted and removed all four partitions. After that I saw that blkdiscard worked. Is this the proper way to remove the old Windows stuff that was encrypted by McAfee? Is there anything else I missed that may bite me later?

did you try:
| Code: | dd if=/dev/urandom of=/dev/sdX
dd if=/dev/zero of=/dev/sdx |

That would murder a solid-state device. You need to use the erase-block size, usually 4MiB (dd if=/dev/zero of=/dev/nvme0n1 bs=4M) or each write will re-write the 4MiB block 4096 times.
I figured it out. I get the PSID on the sticker on the NVME drive itself, then use sedutil-cli to erase it. McAfee uses FIPS stuff to lock and encrypt the drive so you MUST use sedutil.
