Q:

Unable to remove Volume Group due to Incorrect metadata area header checksum

I have three HDDs that I pulled from an old server.  Couldn't remember what was on it or how it was configured until I stuck it into my new server to use for RAID5.  I dd'ed all three hard drives and tried to mdadm --create a new RAID array and got the following error:
mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/sdb /dev/sdc /dev/sdd
mdadm: super1.x cannot open /dev/sdc: Device or resource busy
mdadm: /dev/sdc is not suitable for this array.
mdadm: create aborted

Looking into the problem I found out that /dev/sdc2 still contains a logical volume.
# lsblk /dev/sdc
NAME                    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sdc                       8:32   0 931.5G  0 disk 
|-sdc1                    8:33   0   102M  0 part 
`-sdc2                    8:34   0 931.4G  0 part

# lsblk /dev/sdd

`-sdd2   8:50   0 929.5G  0 part 
# lsblk /dev/sdb
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sdb      8:16   0 931.5G  0 disk 
|-sdb1   8:17   0     2G  0 part 
`-sdb2   8:18   0 929.5G  0 part 

I tried lvremove pvremove and vgremove but all return with the same error: Incorrect metadata area header checksum on /dev/sdc2 at offset 4096
I am unfamiliar with LVM and tried to look online on what to do.  Did a recovery but did not work not to my surprise since the vg file archive I used was generated on my new server.
My guess is that because I dd'ed the HDDs I somehow messed up the header metadata.  What can I do to wipe all this so that I can create my RAID5?  Any help would be much appreciated.
Thanks in advance!
EDIT
To clarify what I mean by dd'ed:
dd if=/dev/zero | pv | dd of=/dev/sdx
EDIT 2
Just to clarify what helped and give credit to both answers.  Both answers below with regards to dd work.  In my case, since the RAID was built on a different box, and I orphaned one of the drives, my new box was complaining about the volume group and such.  When I used dd initially to wipe the data I must not have touch the headers for the RAID/LVM.

A:

As long as you don't care what's on the drive at /dev/sdc, try this:
dd if=/dev/zero of=/dev/sdc bs=1m count=10

That will zero out the first 10 MB of the disk, including any LVM or RAID headers. Then reboot; the system should see that the disk is no longer a part of any LVM group.
