[SOLVED] HELP: Can't partition drives

I'm doing a fresh install of my machine. I was running fakeRAID before and now I want to switch software RAID. But everytime I try to run cfdisk /dev/sda I get an error saying "FATAL ERROR: Bad primary partition 2: Partition ends after end-of-disk. press any key exit cfdisk". How do I remove the old RAID or deactivate it. I turned it of in the BIOS.

cfdisk -z /dev/sda ..try this one the  " -z" means zero MBR ,and re-partition you're hdd or save it 'blanc' and do the 'arch-setup'

Re: [SOLVED] HELP: Can't partition drives

Thanks that worked but my installation is messed now with software raid. I have a pv named /dev/md127 inside my vg0 that I can't remove. I try to

pvremove /dev/md127 but I keep getting the error PV belongs to Volume Group vg0. How do I remove /dev/md127?

I also tried

mdadm --incremental /dev/md127

but I just get a message saying "cannot open /dev/md127: Device or resource busy"
