I have found a utility that will avoid you having to use the workaround for HPA. This utility will allow you to remove the HPA from your hard drive permanently in most cases. You have to have the hard drive on a SATA port that is in AHCI mode, not in RAID mode when you run this bootdisk and utility. My RAID was one with redundancy, and my motherboard has an extra separate SATA controller to add two more ports, so what I did was move the drive with the HPA over to that extra port and put that in AHCI mode, then used the utility to remove the HPA. After that, I put the drive back, and let the RAID rebuild, without any loss of data. This would also work if you put the drive on a separate computer with an AHCI controller. I don't know what would happen if you changed your RAID controller to AHCI mode, but I suspect it would break the array permanently, so make a backup if you have to do this.
Here is the utility: http://www.hdat2.com/ This solved all my problems with Linux and unmodified Live CDs, too. Now it all just works. Anyone else with a Gigabyte board that has Xpress Recovery like mine should be careful never to turn that on again, or you'll have the HPA back. I have read that there are some Dell computers out there that also have code in their boot sector to make them re-create the HPA even if you delete it. If you have one of those, you will have to do more work to make this permanent. -- HPA ( Host Protected Area ) interferes with dmraid https://bugs.launchpad.net/bugs/219393 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
