Comment 1 for bug 606889

I consider this mystical solved, please mark the bug report as invalid.

What happened? I have 2 harddrives, one spare where I sometimes dd-copy my first harddrive to. I did this the first time after my ubuntu 10.04 install the day before yesterday. With two harddrives being identically, their UUIDs were so too and bootloader and kernel decided to use the wrong one (the first time where my data disappeared) and the right one (the time where my data reappeared). Which one the kernel chose was quite random and not visible during boot so I didn't realize it was working on the wrong drive. That's all.
