I am trying to setup a new computer with a software raid0. I am running 32 bit Ubuntu 12.04. I have my OS installed on a PATA Hard Drive, and 4 SATA 2TB Hitachi Drives to be raided. The Motherboard is an ASUS M2N-L, which uses nForce 570 SLI / NVIDIA MCP55 (rev a3) for it's on-board SATA controller. Im aware software raid may not be the best, but I have several other machines with this setup that work excellent for my purposes.
I was able to successfully build and start the raid via the Ubuntu GUI Disk Utility, but it gave me an error, that the partition was offset would run very slow and suggested I should re-partiton. I did re-partition, but that simply resulted in more errors... cannot find device, or offset problems, eventually I came back around to the partitioning step and I was able to mount the drive despite the error message, but it was indeed slow. And continuously failed to capture DV Video. ( The other raids like this in my office capture 8 streams at a time )
I have since swapped all 4 SATA cables, swapped the ports used and swapped the Motherboard itself ( I have 2 of this ASUS M2N-L ). I have also swapped 1 of 4 2Tb Hard Drives. ( I have 6, will eventually have 8 in two 4 drive Raid0's in this box ) I have the BIOS updated to most recent. I have tried manually using mdadm to asseble and create a raid array, but they always fail to format a filesystem. The GUI sometimes will let me try and mount, but it always came back with errors like, look in "dmesg | tail". Bad superblock ... I looked this up and I tried to "repair" from an alternate superblock, but that also failed.
Additionally through out this process I've been checking back to the Disk Utility GUI and found that occasionally 1 of the 4 drives will disappear, or one of them will loose SMART DATA status. If I restart, all drives and all SMART DATA return. ( Boot shows all drives, all with SMART )
In my mind all the observations point to a driver conflict with Ubuntu, but I didn't find anyone else complaining of issues with my combination of hardware? ASUS has "Linux Drivers" but none for any Debian based liunx, I tried converting rpms and installing, but that either didn't work or had no effect ( is it the same driver already included with Ubuntu? )
Any ideas whats to blame or how to fix it? I'll be happy to post any specific data, just ask, Im not sure whats relevant at this point... thanks in advance. -Mark
1st Edit: OK, attempting to re-create original error message that created a working raid, but was too slow. In order to do that, Im trying to delete the partitions on each drive and I get this error:

I'll try and re-create that original error again... but as you can see I've seen many a error on this venture! Thanks again!
2nd Edit: I can't seem to get back to all empty hard drives in order to reproduce the original error! 1 of the 4 drives refuses to delete...

I also tried wiping the drive with dd

Seems odd that a 2TB drive is full after writing 1.2 GBs? Since I can't seem to erase this drive I can't re-create my original error message... but something tells me that all these errors point to the same reason why I got an error in the first place.. if they point to anything at all.
