Hmmm .... it was completely irresponsible of me not to point out that the sgdisk "Zap" command above is dangerous - it removes everything (MBR, GPT, partitions) from a hard drive. Use it cautiously. Check and double check that the correct disk is being addressed. Read documentation on gdisk. K?

Thank you to the people who looked at this topic. What I found that finally worked was gdisk. sgdisk --zap-all /dev/sdX Run in Linux terminal as root. Where X represents a, b, c, etc or whatever the real designation is.

I have a Force LE drive which was used in a Legacy BIOS system running Ubuntu 1804. I would like to re-purpose it for use in a UEFI BIOS system. Secure Erase from the Corsair Tool Kit does not remove the Linux MBR. Neither gdisk or dd in Linux will remove the Linux MBR. Diskpart/clean in Windows 10 will not remove the Linux MBR. Both Windows 10 and Linux Mint 19.03 will install on the drive in the UEFI system but will not boot - disk read errors reported at boot. The drive continues to work in the Legacy BIOS system where it was originally installed if I reinstall Linux on it. Corsair Tool Kit, such as it has diagnostics, does not report any errors with the drive. How can I reset this drive to factory defaults so that I can re-purpose it? Thanks. Cheers.
