Yes, if you previously used the disks in raid mode and no longer wish you, then you need to remove the raid metadata from the disks by either destroying the raid set with the bios utility, or the -E switch to dmraid. Simply disabling the raid mode in the bios leaves the metadata on disk and the bios ignores it, but Ubuntu does not know that and will continue to try using it.
If this does not resolve your issue, please update this report. ** Changed in: dmraid (Ubuntu) Status: New => Incomplete -- Ubiquity can't find the sata hard disk (promise 376 chip) https://bugs.launchpad.net/bugs/543008 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
