The title of this should probably read 'hard drive goes missing after reboot'.
On some advice I got from linuxquestions.org, I tried the Knoppix livecd. It successfully found and mounted the partitions that were made within Ubuntu. Some test files I created on it from within ubuntu were accessable and everything. Ubuntu still can't see /dev/sda1 after a reboot. It seems to be some but with detecting the partitions table. - Peter -- Hard drive goes missing after install https://launchpad.net/bugs/53385 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
