Hi crew,
Just a curiosity I have that someone may have an answer for.
I had created a 4tb raid0 volume [2 x 2tb seagate barracuda] on a intel c600 controller, then removed them from that m/b and connected them one at a time [disconnected all other drives] to an older m/b with a ICH5 controller, booted and checked that the controller was not in raid mode and booted seatools dos to erase sector 0 only.

Then reconnected them back to the c600 controller and was surprised to see that the controller still saw both hdd's as member disks in raid config. when I was expecting them to show as non-member disks.
What have I missed?

The raid info is not stored in the MBR

Yeah sorry, knew it was gpt that I had to kill, but forgot to mention that I also wiped many lba's at the start, then discovered that the gpt is also written to the end lba's.
Diskpart is my friend

The raid info is also not stored in the gpt data

Maybe I didn't ask the right question. Diskpart achieved what I wanted
