Hashcat wrong Hash "Veracrypt loader damaged"

Hello,

i want to brute my own HDD.
When i get the hash with DD Hashcat says "no hash loaded"
so i looked into the hash file and it does not look normal, it looks like normal but it also says "veracrypt loader damaged, use rescue disk"

I tested it with a USB-Stick and same dd command, i get an valid hash.

I also send the HDD to a big company because i thought the HDD is damaged, but its not damaged.
So what could be the problem? is it just a format problem?

Hopefully someone can help me.

got the hash with sudo dd if=/dev/sdb of=disk bs=512 count=1

regards
