The solution you found indicates that a BIOS fakeraid was setup on those disks, you may have done it accidentally when playing with BIOS settings.
Unfortunately the useful information was erased when you did dmraid -E. In Ubuntu 9.10 fakeraid became a default option during setup, you could actually disable dmraid upon boot of the install CD (with the nodmraid option) which would have disabled it completely. Dmraid has no effect on normal untouched disks, if it did have an effect we would see a lot more bug reports! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760940 Title: dmraid mounts inexistent arrays -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
