I experienced this too when trying to install Ubuntu 10.04 i386 (released version).
My computer is an old eMachine, with the original disk. It has never been RAIDed. Heck, the machine doesn't have the appropriate controller and has never had a second drive. I had a difficult time figuring out what was going on from the symptom (no disks found for installation). I ended up adding tracing instructions to the shell script /lib/partman/init.d/30partd and staring at /var/log/user.log. Yuck. I found "dmraid -r -d" said DEBUG: not isw at -224961536 DEBUG: isw trying hard coded -2115 offset. DEBUG: not isw at -226043392 /dev/sda: pdc, "pdc_jjacgccf", stripe, ok, 234441472 sectors, data@ 0 I don't know what to make of this, but I did a "dmraid -r -E" based on this launchpad entry. Seems to work. I hate to think what a random user would have done in this case. I had no trouble installing Fedora 4 on this box years ago. -- 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
