Comment 17 for bug 68490

I've had the exact same problem. STR will corrupt the super block off of the bootable linux partition, and the other drives just wind up corrupted. So /dev/sd[boot] winds up having to be reformatted (because everything is in /lost+found), but everything is okay after the journal recovers. Other not in use partitions (such as Windows partitions) are unaffected, except for the fact that my boot loader can't load until I reinstall Ubuntu.
