I'm attempting to format an NVME drive to use in my server. It was a main boot drive on a former PC running Windows, and for some reason it now seems it ooes not want to clear the 'SYSTEM' partition from the drive. When the drive is cleared, it looks fine and gives me the option to format, but no matter what I am formatting to it will all of a sudden show the SYSTEM partition and the 'UDEV' icon (as pictured), I assume saying it failed to format. And my only option then is to clear the drive once again (No option to clear partition)

 

I have attempted using UD Preclear, as well as fdisk in Terminal, all to no avail.

 

Any recommendations?

Try blkdiscard /dev/nvme1n1 ( double check the device name have change or not before command fire )

Thanks Vr, I did give that a go as well but no luck. It turned out for some reason the solution would up being that adding it to a pool and then formatting both drives together in the pool worked, where as trying to format the drive on its own in UD wouldnt. Interesting circumstance but problem solved non the less.
