Cant wipe /create/ etc

[BrutalRage]

Hiya,
I am new to FreeNAS.
Just got a new machine for storage.
Bought 6 new sas drives.

All the 6 drives show up nice in FreeNAS.
Running FreeNAS-9.10.1-U2
Intel(R) Xeon(R) CPU E5630 @ 2.53GHz
32729MB
It is a PowerEdge C2100

So I'll show you what I do and what errors I get
First I try all 6 disk into a volume I get:
out: Unable to GPT format the disk "da0"

So il try to wipe the disks:
out: Failed to wipe da0: dd: /dev/da0: Invalid argument 1+0 records in 0+0 records out 0 bytes transferred in 0.007177 secs (0 bytes/sec)

Next il try to do it differnt:
gpart destroy /dev/da0
gpart: Device not configured

Then I checked importing volume.
It cant but it tells me that the disk are in ntfs.

Than googled some more and tryed some more commands:
Welcome to FreeNAS

Code:

[root@freenas] ~# sysctl kern.geom.debugflags=0x10
kern.geom.debugflags: 0 -> 16
[root@freenas] ~# dd if=/dev/zero of=/dev/ada4 bs=512 count=1 && dd if=/dev/zero of=/dev/ada5 bs=512 count=1
dd: /dev/ada4: Operation not supported
[root@freenas] ~# dd if=/dev/zero of=/dev/ada0
dd: /dev/ada0: Operation not supported

Please assist.
All the drives are empy so no harm can come to them.

Just checked the bios
in bios it says
Ide configuration
Confiure SATA#1 as [raid] is this correct?

No, don't have them as RAID; Use AHCI.

As far as the drives are concerned, they should be connected to the HBA (LSI 9211-8i). What Make/Model drives are you using (just to be sure).

Changed to AHCI.
Do I have to visual check the make/model?

Nah, lets skip that for now..
